Ecommerce Peak Season Sales Calendar 2026

We know first-hand just how demanding the final few months of the year can be for ecommerce brands. From October through January, order volumes can rise rapidly, putting pressure on stock, staff and your fulfilment operation.

With 150,000 orders passing through our fulfilment operation every month during peak, we know that being prepared isn’t just about getting through Black Friday. It’s about knowing what’s coming, when it’s coming and having the right plans in place to handle it.

To help you stay ahead, we’ve put together our 2026 Ecommerce Peak Season Sales Calendar, highlighting the key dates and opportunities you need to know about from October through to the New Year.

Here are the key eCommerce dates to have on your radar for 2026:

7–8 October: Amazon Prime Big Deal Days (provisional date based on previous Amazon schedules)

Amazon has already held its main Prime Day from 23–26 June this year, but shoppers can typically expect a second major savings event later in the year.

Amazon has not yet officially confirmed the 2026 dates, but its second Prime focused event has historically taken place in October. If you sell through Amazon or compete with Amazon led promotions, it is worth preparing your stock and fulfilment operation ahead of the announcement.

31 October: Halloween

Halloween may not be one of the biggest shopping events of the year, but online sales continue to play an important role in the occasion.

It can be a particularly valuable opportunity for businesses selling sweets, costumes, decorations, gifts and seasonal products.

Make sure your Halloween stock is in place early and consider creating themed promotions, bundles or limited time offers to capture seasonal demand.

8 November: Diwali

Diwali, the festival of lights, is a major shopping season across India and among South Asian communities worldwide.

Shoppers purchase gifts, sweets, festive décor and clothing to celebrate the occasion. For ecommerce businesses, it can be an opportunity to launch culturally relevant promotions, limited edition products and gift bundles.

If you sell internationally, consider whether Diwali should form part of your seasonal marketing calendar and make sure you have enough stock and fulfilment capacity to meet any increase in demand.

11 November: Singles’ Day

The biggest shopping day in the world.

Singles’ Day originated in China in the 1990s as an unofficial celebration for single people. It has since grown into one of the world’s biggest shopping events, with millions of consumers heading online for deals.

For ecommerce businesses, particularly those selling internationally, Singles’ Day can present an opportunity to reach customers in overseas markets and benefit from increased demand for international brands.

If you sell cross border, consider whether Singles’ Day should form part of your international marketing and fulfilment strategy.

27 November: Black Friday

One of the biggest sales days of the year.

Black Friday marks the beginning of the major Christmas shopping period and can bring a significant increase in orders over a short period.

By this point, your stock, warehouse capacity, staffing levels, technology and delivery arrangements should all be ready for increased demand.

Don’t leave your peak preparation until November. Forecast demand, check your inventory and speak to your fulfilment and delivery partners well in advance.

28 November: Small Business Saturday US

Small Business Saturday takes place in the US on the day after Black Friday.

American Express launched the awareness day in 2010 with the aim of encouraging consumers to support small and local businesses.

For ecommerce brands selling into the US, it is another opportunity to showcase your products, promote your brand story and encourage customers to shop small during the busy Christmas shopping period.

30 November: Cyber Monday

Cyber Monday follows Black Friday and gives ecommerce businesses another opportunity to capture customers looking for deals.

Some businesses use Cyber Monday to continue their Black Friday promotions, while others use it to introduce new offers or help shift remaining promotional stock.

Make sure your fulfilment operation is prepared for continued order volumes rather than assuming demand will drop immediately after Black Friday.

5 December: Small Business Saturday UK

Small Business Saturday UK takes place on the first Saturday of December, with the 2026 event falling on 5 December.

It is an opportunity for smaller retailers and independent brands to put their businesses in the spotlight and encourage customers to shop small.

Use the occasion to share your brand story, showcase your products and highlight what makes your business different. It can also be a useful opportunity to build engagement ahead of the final weeks of Christmas shopping.

14 December: Green Monday

Green Monday typically falls on the second Monday of December.

It is often associated with shoppers looking to take advantage of deals while still having enough time for their purchases to arrive before Christmas.

For ecommerce businesses, this is an important date to communicate Christmas delivery cut offs clearly and make sure customers understand when they need to place their orders.

Consider using Green Monday as an opportunity to promote last minute deals while making your delivery options and deadlines clear.

14 December: Free Shipping Day

Usually occurs in mid-December, with the exact date varying each year. This year, it falls on Green Monday, giving ecommerce businesses a great opportunity to combine free delivery offers with last-minute Christmas promotions.

Free Shipping Day is another useful date to consider in your December marketing calendar. Originally created to encourage shoppers to complete their Christmas purchases without paying delivery charges, the event has become associated with free delivery promotions and last-minute online shopping.

If free delivery works for your margins, consider running a limited time offer to encourage customers to complete their Christmas shopping.

19 December: Super Saturday

Also known as Panic Saturday, Super Saturday is the final Saturday before Christmas and one of the biggest last minute shopping days of the year.

Some shoppers will be making their final purchases, while others may be waiting for last minute discounts.

If you offer fast delivery, make it clear across your website, email campaigns and social media. Most importantly, clearly communicate your final Christmas order dates so customers know when they need to buy.

21 December: Last Monday Before Christmas

The final Monday before Christmas is another opportunity to capture last minute shoppers.

At this stage, delivery speed becomes increasingly important. Ecommerce businesses offering next day or express delivery may still be able to capture orders from customers who have left their Christmas shopping until the last minute.

Make your delivery options and deadlines impossible to miss and highlight your fastest shipping options across your website and marketing channels.

25 December: Christmas Day

Christmas Day may be one of the quieter shopping days of the year, but that doesn’t mean customers stop browsing. Many shoppers use the day to relax, scroll through their phones and look ahead to upcoming Boxing Day and January sales.

It’s a good opportunity to build anticipation for your next promotions. Consider teasing upcoming offers, showcasing sale products or reminding customers when your Boxing Day sale will begin.

Key tip: Make sure your website is mobile friendly and easy to navigate. After Christmas dinner, many customers will be browsing from the sofa, so make it simple for them to discover your products and find out what’s coming next.

26 December: Boxing Day

Once Christmas Day is over, the focus quickly turns to the Boxing Day sales.

For retailers, Boxing Day is an opportunity to attract customers spending Christmas money, shopping for items they didn’t receive as gifts, or looking for post-Christmas bargains.

It is also an important opportunity to clear excess seasonal stock before the new year.

Make sure your warehouse and fulfilment operation is prepared for another potential spike in orders, particularly if your Boxing Day promotions launch at midnight.

January: Returnary

The January sales may continue, but so do the returns. Make sure your fulfilment operation is prepared to handle increased returns alongside ongoing orders.

It’s also a great time to target customers focused on their New Year’s resolutions.

Consider promotions on products linked to fitness, travel, home improvement, organisation and other popular New Year goals.

Peak season waits for no one. Is your fulfilment operation ready?

The biggest ecommerce opportunities of the year can also put the greatest pressure on your operation.
