Observances also vary by country: several of these are national or regional, and some are marked on different dates elsewhere. Treat this as a planning prompt, not authoritative scheduling data.

Frequently asked questions
Which March social media holidays are actually worth posting about?
International Women's Day, Ramadan and St Patrick's Day are the March dates with real audience attention behind them, and they are worth planning properly. Most of the rest are invented awareness days: a marketer registered them, and posting about one mainly signals that the account had nothing of its own to say. For March our advice is to skip World Water Day unless the day is genuinely your subject. Two posts you would have made anyway beat ten borrowed from a list.
Which March dates move each year?
Ramadan moves about eleven days earlier each year, so it has recently begun in February or March, and the equinox falls on 20 or 21 March in the northern hemisphere. This page describes the rule that fixes each one rather than printing a date, because a calendar that confidently prints the wrong day for a moveable holiday is worse than no calendar at all. Confirm the exact day against a current calendar before you schedule anything.
How far ahead should I plan March content?
Four to six weeks covers most March dates: long enough to brief creative, get approvals and build the supporting email. If part of your audience observes Ramadan, plan posting times around it rather than only writing the greeting post. Anything involving paid media or stock needs longer.
Where are the other months?
Every month has its own page. The previous one is February and the next is April. The full twelve-month calendar lists all sixty dates in one place with search and month filters, and there is a separate 2027 planning page if you are building a whole year at once.
