March is the busiest month of the first quarter and the one with the most moving parts.
International Women's Day falls on Monday 8 March, Eid al-Fitr closes Ramadan on around 9 March, Holi lights up on 22 and 23 March, and Easter Sunday lands on 28 March 2027, with Good Friday on the 26th.
Add the spring and autumn equinox on the 20th and Earth Hour on the 27th, and it's the densest content month before summer.
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 March 2027.

Social media post ideas for March 2027
International Women's Day on 8 March is the most scrutinised date of the quarter and the one where brands most often get caught out. In most of the world it is a day of mobilisation rather than a shopping occasion: "special discount for women" campaigns and pink-product launches draw criticism almost immediately, and the gap between a company's IWD post and its actual pay data is now routinely checked in public.
Three major religious and cultural moments land in the same month, and each rewards a different tone.
- Eid al-Fitr on around 9 March closes Ramadan and is a celebration of family, food and gifting the commercial peak of the Ramadan period, with buying concentrated in the preceding week.
- Holi on 22 and 23 March is the most visually generous festival of the year and enormously shareable, though it deserves cultural care rather than being used as a colour-splash aesthetic.
- And Easter, with Good Friday on 26 March and Easter Sunday on the 28th, is a public holiday across most of Europe and Latin America: expect a long weekend, lower B2B engagement from the 25th, and a peak for food, travel and family content.
March is also the strongest environmental window of the year, and the dates chain naturally: World Water Day on the 22nd, Global Recycling Day on the 18th, International Day of Forests on the 21st, Earth Hour on the 27th and International Day of Zero Waste on the 30th. For brands with a sustainability story, that's a five-beat sequence rather than five separate posts.
For light, high-reach content the month is excellent: Pi Day on 14 March, Mario Day on the 10th (MAR10), St Patrick's Day on the 17th, International Day of Happiness on the 20th — which coincides with the equinox and works in both hemispheres — and World Piano Day on the 29th, the 88th day of the year, one for each key.
Giveaway dates and campaign ideas for March
March gives you four very different giveaway moments, so it pays to pick rather than run them all.
An Eid giveaway in the week before 9 March reaches a highly engaged audience at its annual peak.
A Holi-themed colour or photo giveaway around 22–23 March produces some of the best user-generated visuals of the year. An Easter egg-hunt mechanic hiding a code or an image across your feed and stories in the week to 28 March is one of the highest-retention formats available, because it requires people to come back.
And a light, fast giveaway on International Day of Happiness on 20 March works equally well in both hemispheres, since it lands on the equinox. With Simpliers you can run Instagram giveaways in seconds, transparently and verifiably.
