January is the month of fresh starts and of resolutions that quietly fall apart.
It opens with New Year's Day, runs through Veganuary and Dry January, hits Quitters Day on 8 January and Blue Monday on 18 January, and closes with the International Day of Education and International Holocaust Remembrance Day. It's a quiet month for retail but an unusually good one for building an audience.
To help you plan your brand's campaigns, Instagram giveaways and social media content, we've put together the complete calendar of special days in January 2027.

Social media post ideas for January 2027
January rewards patience. Purchase intent is at its lowest point of the year after the December peak, but attention is unusually cheap and audiences are actively looking for new habits, new tools and new things to follow. This is the month to grow a following rather than to sell to one.
The strongest hook of the month is the resolution arc, and it has two dates built into it. Quitters Day falls on 8 January the second Friday, statistically when most New Year's resolutions collapse — and Blue Monday lands on 18 January.
Blue Monday has no scientific basis (it started as a travel-company PR campaign), and audiences increasingly know that, so the brands that win the day are the ones that acknowledge it with a wink or turn it into something genuinely supportive rather than selling "cheer yourself up" discounts. Paired with Mental Wellness Month, it's the best mental-health conversation window of the first quarter.
Veganuary and Dry January are the two biggest month-long campaigns, and they matter far beyond food and drink brands: both generate enormous "how's it going" content and both have a natural mid-month slump around the 15th that's perfect for a check-in post.
For pure reach, January is unusually generous with light content: International Hugging Day on the 21st, Global Belly Laugh Day on the 24th, International LEGO Day on the 28th and World Croissant Day on the 30th all perform well in short-form video. World Beatles Day on the 16th and Wikipedia Day on the 15th are strong for brands with a cultural or tech angle.
One note on dates that move: Epiphany on 6 January is a public holiday in much of Europe and Latin America, and Orthodox Christmas on 7 January is observed by churches following the Julian calendar so if your audience spans those regions, the first week of January is quieter than your analytics baseline suggests.
And look ahead: Lunar New Year 2027 falls on 6 February, so campaigns for it need to be built in the last week of January.
Giveaway dates and campaign ideas for January
January is the cheapest month of the year to grow a community, which makes it the best month for a giveaway that asks for a follow rather than a purchase.
You could run a "resolution kit" giveaway in the first week, while motivation is still high; time a pick-me-up giveaway to Blue Monday on 18 January, which reliably outperforms the rest of the month for engagement; run a Veganuary or Dry January prize mid-month, when participants are looking for encouragement; and close with a light, high-participation giveaway around International LEGO Day on the 28th or World Croissant Day on the 30th.
With Simpliers you can run Instagram giveaways in seconds, transparently and verifiably.
