Ecommerce Marketing Calendar: Key UK and US Dates for Brands

Key Takeaways

• Black Friday 2027 is Friday 26 November and Cyber Monday is Monday 29 November, but most of the big moments need planning months earlier.
• UK and US dates differ: Mother's Day falls on 7 March in the UK and 9 May in the US, and Small Business Saturday is 4 December in the UK and 27 November in the US.
• 2027 brings unusual clashes: Super Bowl LXI lands on Valentine's Day, and the London Marathon runs over two days, 24 and 25 April, for 100,000 runners.
• Amazon moved Prime Day to 23 to 26 June in 2026, so keep Prime Day 2027 flexible until Amazon confirms the dates.
• Choose the dates that fit your sector, from Veganuary and International Tea Day to National Dog Day and World Afro Day, rather than marketing around every awareness day.
• Apart from welcome discounts, the Black Friday code normally generates the most revenue for Why Matters clients, and our PR campaigns take six weeks on average to land first coverage.

Quick Answer

An ecommerce marketing calendar lists the dates that shape customer demand, so you can plan campaigns early. For UK and US stores in 2027, the biggest moments are Valentine's Day (14 February), Mother's Day (7 March in the UK and 9 May in the US), Father's Day (20 June), Prime Day (dates to be confirmed), back to school, Halloween, Black Friday (26 November), Cyber Monday (29 November) and Christmas. Add the sector days that suit your products, and start work at least six weeks before each one.

A coffee brand that first thinks about National Coffee Day on 28 September has missed most of the opportunity. This 2027 calendar brings together the major UK and US retail dates, sector days and awareness days that suit Shopify brands, so you can work backwards to landing pages, press, email and stock in good time.

How to Use This Ecommerce Marketing Calendar

Do not market around every date, or your emails become "Happy International Something Day, here is 10% off". Choose occasions with a genuine link to your products, customers and expertise: a coffee brand might build around both coffee days, Father's Day and Christmas, while a sustainable cleaning brand cares more about Earth Day and Plastic Free July.

Each date is tagged UK, US or both, with the sectors it suits: beauty (including skincare and haircare), health (including supplements and vitamins), drinks (coffee, tea, beverages and snacks), pet, baby, home (household and cleaning) and eco. Many "national days" are informal, and dates marked to confirm had not been announced at the time of writing. Then give every event a start date, using the lead times in the FAQs below.

2027 at a Glance

Two headline moments per month, then the months that matter most for each sector.

UK vs US: The Dates That Differ

If your store sells into both countries, for example through Shopify Markets, these are the moments that need separate planning:

January 2027

January means new routines and tighter budgets, which suits health, habit, subscription and practical reset products. Pitch January stories to the press from mid November 2026.

Veganuary: All of January

UK and US | Awareness month | Health, beauty, eco, drinks

Veganuary began in the UK in 2014, and the charity estimates around 30 million people worldwide took part in 2026, with at least 1,187 new products and menu items launched for the campaign (Veganuary). Email an "easy swaps" guide, share one swap a week on social and build a vegan starter bundle, but only call products vegan if you can prove it, and remember that vegan and cruelty free are different claims.

• Friday 1 January, UK and US: New Year's Day. All sectors; frame products as small, realistic routines without miracle claims.
• All month, UK: Dry January and the January sales. Drinks and health; promote alcohol free options without criticising drinkers, and keep reference prices genuine.
• All month, US: National Hot Tea Month. Drinks; an informal hook for brewing guides and subscriptions.
• Monday 18 January, UK: Blue Monday. Health and beauty; treat it as a marketing idea, not science. It is also Martin Luther King Jr. Day in the US, so avoid sales messaging there.

February 2027

Gifting returns, and February 2027 is crowded, with Lunar New Year, the expected start of Ramadan, Valentine's Day and the Super Bowl landing within about eight days. Start Valentine's press outreach in late December.

Valentine's Day: Sunday 14 February

UK and US | Big sales day | Beauty, drinks, pet

US shoppers were expected to spend a record $29.1 billion on Valentine's Day in 2026, an average of $199.78 each (NRF), and gifting now reaches friends, family and pets as well as partners. Segment gift ideas by recipient, build bundles with a clear delivery cut off, and avoid copy that excludes people who are single or grieving. Super Bowl LXI is on the same day at SoFi Stadium (SoFi Stadium), so US inboxes will be unusually busy, and NFL branding is protected, so never imply an official link.

• Saturday 6 February, UK and US: Lunar New Year. Drinks and beauty; work with people who know the culture.
• Around Monday 8 February: Ramadan expected to begin. Drinks; suhoor and iftar content for relevant audiences, and dates can shift by a day.
• Tuesday 9 February: Pancake Day and Mardi Gras. Health foods and snacks; recipes built around your products.
• Monday 15 February, US: Presidents' Day sales. All sectors; an established US promotional weekend.
• Late February, UK: Fairtrade Fortnight (to confirm). Coffee, tea and snacks; explain your sourcing.

March 2027

An early Mothering Sunday and an early Easter make March busy, so UK Mother's Day press work should start in late January and Easter outreach by mid February.

Mother's Day (UK): Sunday 7 March

UK | Big sales day | Beauty, drinks, baby

Mothering Sunday falls on the fourth Sunday of Lent, so it is unusually early in 2027, and "Mother's Day is early this year" is a genuinely useful subject line. Build gift edits by interest, such as tea lover or skincare fan, show dispatch deadlines clearly, and let subscribers opt out of Mother's Day emails without unsubscribing, because the day can be painful for some customers.

• All month, US: National Nutrition Month. Health; educational content with compliant claims.
• Monday 8 March: International Women's Day. Beauty and health; only if it connects with what you do.
• Around Wednesday 10 March: Eid (expected). Drinks and beauty; culturally informed gifting.
• Wednesday 17 March: St Patrick's Day. Drinks and snacks.
• Thursday 18 March: Global Recycling Day, and Monday 22 March: World Water Day. Eco and home; explain how to recycle your packaging.
• Friday 19 March: World Sleep Day. Health and herbal drinks; avoid treatment claims.
• Friday 26 to Monday 29 March: Easter weekend. Drinks, snacks and baby; show delivery deadlines early.

April 2027

April turns to wellbeing, pets, running and sustainability. Start Earth Day press outreach in early March.

Earth Day: Thursday 22 April

UK and US | Awareness day | Eco, home, beauty

Earth Day has been held on 22 April since 1970, and its scale makes it a magnet for vague environmental marketing. Instead of "we love the planet", email an update on what you have actually changed, such as packaging removed or refill uptake, and only use words like green or sustainable if you can prove them; our sustainable Shopify store guide covers the groundwork.

TCS London Marathon: Saturday 24 and Sunday 25 April

UK | Sporting event | Health

For one year only, the London Marathon runs over two days in 2027, with 100,000 participants after 1.33 million people entered the ballot (London Marathon Events). Sports nutrition and recovery brands should publish training content months ahead, and the Boston Marathon on Monday 19 April does the same job in the US, without implying an official link to either event.

• Wednesday 7 April: World Health Day. Health; credible education rather than a hard sell.
• Sunday 11 April, US: National Pet Day. Pet; customer pet stories and care content.
• Wednesday 21 April, UK: National Tea Day. Drinks; an informal date for sampling and brewing guides.
• All month: Stress Awareness Month, plus National Pet Month in the UK (both to be confirm). Health, drinks and pet.

May 2027

Long weekends, US gifting and wellbeing campaigns shape May, and US Mother's Day press work should start in late March.

Mother's Day (US): Sunday 9 May

US | Big sales day | Beauty, drinks, baby

US Mother's Day falls on the second Sunday in May, and the NRF expected record spending of $38 billion in 2026, or $284.25 per person (NRF). UK brands selling into the US need a separate campaign with US delivery deadlines, UK customers should not still see Mother's Day messages two months after Mothering Sunday, and the same opt out applies.

• Monday 3 May, UK: Early May bank holiday, and Monday 31 May: UK Spring bank holiday and US Memorial Day. All sectors; long weekend bundles, with respectful Memorial Day copy.
• All month, US: Mental Health and Skin Cancer Awareness Months, with UK awareness weeks (to be confirmed). Health and SPF beauty; responsible content with no treatment claims.
• Thursday 20 May: World Bee Day. Eco and health; only if pollinators link to your ingredients.
• Friday 21 May: International Tea Day. Drinks; a UN day for origin stories, producers and tea subscriptions.
• UK Coeliac Awareness campaign (to be confirmed). Health foods; be precise about gluten free claims.

June 2027

Summer, Father's Day and environmental days shape June, and Father's Day press work should start in early May.

Father's Day: Sunday 20 June

UK and US | Big sales day | Beauty, drinks, health

Father's Day falls on the third Sunday in June in both countries, so one campaign can serve both markets in 2027. Try "gifts for dads who don't need more socks", build a gift finder around interests such as coffee, grooming or fitness, offer prepaid subscriptions for consumables so the gift keeps arriving, and give subscribers the option to opt out.

• All month: Pride Month. All sectors; real support, not just a rainbow logo.
• Wednesday 2 June: Global Running Day. Health; training and recovery content.
• Saturday 5 June: World Environment Day, and Tuesday 8 June: World Oceans Day. Eco and home; report changes you can prove.
• Men's Health Week (to confirm). Health and grooming; no unsupported claims.
• Wednesday 16 June: World Refill Day (to confirm). Eco, home, beauty and drinks; show refill savings.
• Saturday 19 June, US: Juneteenth, observed Friday 18 June. No sales messaging.

July 2027

Summer shopping, holidays and heavy discounting make July busy, but do not assume Prime Day will stay in July.

Amazon Prime Day: Dates to Be Confirmed

UK and US | Big sales event | All sectors

Amazon moved Prime Day to 23 to 26 June in 2026, when Adobe measured $26.4 billion of US online spending across the retailers it tracks, up 9.3% (Adobe). Shoppers become more price conscious everywhere, so keep a flexible plan and compete with exclusives, bundles, loyalty and service, never implying an official Prime Day link.

• Sunday 4 July, US: Independence Day, observed Monday 5 July. Drinks and snacks; pet brands should share fireworks advice days before.
• All month: Plastic Free July. Eco, home, beauty and drinks; show what your company has changed first.
• Wednesday 7 July: World Chocolate Day, and Sunday 18 July, US: National Ice Cream Day. Snacks; informal days for recipes and limited editions.
• Saturday 24 July: International Self Care Day. Beauty and health; evidence based wellbeing content.

August 2027

Back to school starts earlier than most calendars assume, especially in the US, so plan US campaigns from early summer and UK campaigns from late July.

Back to School: July to September

UK and US | Big retail period | Baby, drinks, health

Focus on the problem rather than the event: lunchboxes, morning routines, snacks and family wellbeing. Share checklists for parents, build multipacks or subscriptions for repeat purchase products, and take extra care with any advertising that involves children.

• Sunday 1 to Saturday 7 August: World Breastfeeding Week. Baby; supportive content only, remembering that infant formula advertising is tightly restricted in the UK.
• Sunday 8 August: International Cat Day, and Thursday 26 August: National Dog Day. Pet; customer pets and care advice.
• Monday 30 August: Summer bank holiday in England, Wales and Northern Ireland. All sectors; Scotland's was Monday 2 August.

September 2027

Routines return, making September strong for replenishment, health, coffee and household brands. Coffee brands should pitch National Coffee Day stories by mid August.

National Coffee Day (US): Wednesday 29 September

US | Informal day | Drinks

National Coffee Day is a widely used US marketing occasion rather than an official holiday, and International Coffee Day follows on 1 October. Introduce a new roast, discovery bundle or brewing guide, and offer a subscription trial rather than discounting every bag, since coffee suits Shopify subscriptions.

• All month, UK: Organic September and Second Hand September (to confirm). Health, beauty and eco; explain certifications properly.
• All month, US: Baby Safety Month. Baby; safe use content without fear.
• Wednesday 15 September, UK: World Afro Day. Beauty; textured hair education.
• Monday 20 September: World Cleanup Day. Eco and home; a UN day, fixed on 20 September by a 2023 resolution (United Nations).
• UK Zero Waste Week, Recycle Week and National Fitness Day (to confirm). Eco, home and health.

October 2027

Autumn habits and early gifting build through October, and Halloween stock and creative should be ready before the month begins.

International Coffee Day: Friday 1 October

UK and US | Awareness day | Drinks

The International Coffee Organization set 1 October as International Coffee Day, first marked on a shared date in 2015, so use it for a broader story about producers, origins and the supply chain rather than repeating your National Coffee Day offer.

• Sunday 31 October: Halloween. Snacks, beauty and pet; themed bundles, makeup tutorials and a reminder that chocolate is dangerous for dogs.
• Sunday 31 October, UK: Clocks go back. Vitamins; the NHS suggests people consider vitamin D in autumn and winter, which is a content hook, not a product claim.
• All month: Breast Cancer Awareness Month. Beauty and health; be transparent about any donation.
• Sunday 10 October: World Mental Health Day, and 9 to 15 October, UK: Baby Loss Awareness Week. No promotional activity.
• Monday 18 October: World Menopause Day. Health; credible information only.
• Friday 29 October: Diwali (expected), plus Prime Big Deal Days (to confirm). Gifting, drinks and beauty.

November 2027

November is ecommerce's promotional peak, and the strongest brands settle their Black Friday plan months earlier.

Black Friday: Friday 26 November

UK and US | Big sales day | All sectors

Black Friday falls the day after US Thanksgiving. Shopify merchants sold $14.6 billion over Black Friday Cyber Monday 2025, with the UK their second biggest selling country (Shopify). Use clear offers, bundles and subscriber exclusives, keep savings claims and countdowns genuine, and see our Black Friday guide for the full plan; eco brands can choose Green Friday or Buy Nothing Day instead, as long as the rest of their marketing matches.

• All month: Movember and World Vegan Month. Grooming, health and vegan beauty.
• Friday 5 November, UK: Bonfire Night. Pet; fireworks advice before the evening.
• Thursday 11 November: Remembrance Day and Veterans Day. Pause ordinary sales messaging.
• Sunday 14 November: World Diabetes Day. Health; no medical claims.
• Thursday 25 November, US: Thanksgiving, then Small Business Saturday on 27 November. Drinks for entertaining, and why buying direct matters.
• Monday 29 November: Cyber Monday, and Tuesday 30 November: Giving Tuesday. All sectors; follow the discounts with genuine giving.

December 2027

December moves from gifting to delivery anxiety, then to Boxing Day and New Year, so pitch Christmas press stories from October or earlier.

Christmas Day: Saturday 25 December

UK and US | Big retail season | All sectors

Christmas is a two month season, so move from gift discovery to delivery countdowns and last minute options. Show last order dates, gift cards and returns information prominently, and never promise Christmas delivery you cannot meet; Royal Mail had not published its 2027 posting dates at the time of writing. The US federal holiday is observed on Friday 24 December, and the UK substitute bank holidays fall on Monday 27 and Tuesday 28 December.

• Saturday 4 December, UK: Small Business Saturday (to confirm). All sectors.
• Monday 13 December, US: Green Monday. A shopping day, not an eco day.
• Friday 24 December: Hanukkah begins at sunset (expected). Gifting; plan it separately from Christmas.
• Sunday 26 December: Boxing Day sales in the UK, and Kwanzaa begins in the US. All sectors.
• Friday 31 December: New Year's Eve. Drinks and health; lead into Veganuary and Dry January.

UK Paydays and the Rest of 2026

Many UK employers pay on the last working day of the month, although there is no universal payday. In 2027 that means 29 January, 26 February, 31 March, 30 April, 28 May, 30 June, 30 July, 31 August, 30 September, 29 October, 30 November and 31 December, though December pay often arrives earlier, so test payday against your own data. If you are reading this before 2027, Black Friday is Friday 27 November 2026, Cyber Monday is Monday 30 November, Giving Tuesday is Tuesday 1 December, UK Small Business Saturday is Saturday 5 December, Green Monday is Monday 14 December and Christmas Day is Friday 25 December.

Rules to Check Before You Promote

An awareness day never widens what you are allowed to claim. Since 5 January 2026, UK paid online ads for identifiable less healthy food and drink have been banned, although businesses with fewer than 250 employees placing their own ads are out of scope and brand ads are exempt (ASA). Supplement and health food brands must stick to authorised nutrition and health claims in the UK and meet US rules when selling there, infant formula advertising is tightly restricted in the UK, environmental claims need evidence, and every sale needs genuine reference prices and deadlines.

Why Matters Perspective

The dates are the easy part; the advantage comes from choosing well and starting early. Across our last eight client PR campaigns in 2025, first press coverage took six weeks on average, which is why every date in our clients' calendars carries a start date as well as an event date. And apart from welcome discounts, the Black Friday code is normally the one that generates the most revenue for our clients, helped by genuine urgency and email, so the email list you build through the year is what makes the big dates pay.

Why Matters is a Shopify Select partner with Verified Skills across development and marketing. Our pricing is published, retainer clients are billed one month in arrears and never tied into long contracts, and every development project carries a 3 month guarantee. See our Shopify packages or email us to plan your 2027 calendar.

Frequently Asked Questions

What is an ecommerce marketing calendar?

An ecommerce marketing calendar is a year planner of retail, cultural, seasonal and sector dates that affect demand, so you can plan email, social, PR, ads, website content and stock well before each moment.

What are the biggest ecommerce dates in the UK and US?

Black Friday, Cyber Monday and Christmas lead the year, followed by Valentine's Day, Mother's Day, Father's Day, Prime Day, back to school and Halloween, while sector dates such as National Coffee Day can matter as much to specialist brands.

When is Black Friday 2027?

Black Friday 2027 is Friday 26 November, the day after US Thanksgiving, and Cyber Monday follows on Monday 29 November.

When is Mother's Day 2027 in the UK and US?

UK Mothering Sunday is Sunday 7 March 2027 and US Mother's Day is Sunday 9 May 2027, so stores selling to both countries need two separate campaigns.

How far ahead should I plan seasonal campaigns?

Allow days to two weeks for a quick social post, two to six weeks for email and onsite campaigns, four to eight weeks for new bundles or creative, around six weeks for PR, and several months for Black Friday and Christmas.

Are national days like National Coffee Day official?

Often not. International Coffee Day on 1 October is set by the International Coffee Organization, while US National Coffee Day on 29 September is an informal industry occasion rather than a federal holiday.

What advertising rules should food, drink and supplement brands check?

In the UK, paid online ads for identifiable less healthy food and drink have been banned since 5 January 2026, although businesses with fewer than 250 employees placing their own ads are out of scope. Health and supplement brands must stick to authorised claims, and US campaigns must also meet US rules.

Final Thoughts

An ecommerce marketing calendar should make you more selective, not noisier. Pick the moments where your product, customers, sector and expertise have something useful to say: coffee brands around both coffee days, subscriptions, Father's Day and Christmas; beauty brands around Mother's Day, SPF season, World Afro Day and Christmas; eco brands around Earth Day, World Environment Day and Plastic Free July. Then plan early enough to make each campaign worth noticing.
