Short answer: Singles' Day (双十一), held every 11 November, is the world's biggest online shopping festival — bigger than Black Friday and Cyber Monday combined. What started as an "anti-Valentine's Day" for single people became a shopping phenomenon after Alibaba turned it into a sales event in 2009. It's now the single most important date on the Chinese retail calendar.
If you've seen it called Singles' Day, Double 11, 11.11, or Double Eleven — they're all the same event.
Where Singles' Day came from
The date 11/11 was chosen because the four "1"s look like "bare sticks" (光棍), Chinese slang for single people. It began as a light-hearted university celebration of being single. In 2009, Alibaba adopted it as a one-day online sale — and it exploded. It has since spread across every major Chinese e-commerce and social platform.
How big is it, really?
- Alibaba alone has recorded tens of billions of US dollars in sales in a single day
- It routinely moves more GMV than the entire US Black Friday–Cyber Monday weekend
- The event has stretched from one day into a weeks-long presale-and-promotion season running through early-to-mid November
How Singles' Day actually works
It's not just "everything on sale for a day." The modern 11.11 is a coordinated campaign season:
- Presales and deposits. Shoppers pay deposits weeks early to lock in deals.
- Livestream shopping. Top hosts sell staggering volumes in single livestreams — a channel that barely exists in the West.
- Platform-wide games and coupons. Gamified discounts, red envelopes, and cross-store vouchers drive engagement for weeks.
- Content build-up on social. Brands seed Xiaohongshu (RedNote) and Douyin for months so they're top-of-mind before the sale.
Why it matters even if you're not in China
Here's the part most Western businesses miss. Singles' Day isn't only a mainland-China event — the Chinese-speaking diaspora shops it too. Chinese communities in Australia, the US, the UK and Singapore buy heavily during 11.11, both cross-border and from local businesses that show up for it.
For an overseas business serving Chinese-speaking customers, ignoring Singles' Day is like a Western retailer ignoring Black Friday. Even a modest, well-timed promotion — announced on the right platform, in the right language — signals you understand your customer. It pairs naturally with a Lunar New Year push as the two biggest moments in the Chinese consumer year.
How brands prepare (the short version)
- Start content and awareness weeks ahead, not on the day
- Build a presence where decisions happen — Xiaohongshu, WeChat, Douyin
- Have a genuine offer; Chinese consumers compare hard and spot fake discounts
- Plan fulfilment for a spike
