Pollinator and biodiversity content for food, garden and beauty brands.
Differs by country — the second Sunday in May in the US, Canada, Australia and Germany, but March in the UK and Ireland, and other dates elsewhere.
Gift guides; offer an opt-out from the email series, because many people find the day painful.
The whole of May in the US; the UK marks an awareness week in May.
Employee stories and real quiet-hours policies land better than a stock quote card.
The last Monday in May (United States).
A major US sale weekend that is also a solemn remembrance day — keep the two apart.
Dates marked "Movable" shift every year — always confirm the exact day against a current calendar before you schedule anything. 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 May social media holidays are actually worth posting about?
Mother's Day, Mental Health Awareness Month and Memorial Day are the May 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 May our advice is to skip Star Wars Day unless the day is genuinely your subject. Two posts you would have made anyway beat ten borrowed from a list.
Which May dates move each year?
Mother's Day is the second Sunday in May in the US, Canada, Australia and Germany but March in the UK and Ireland, Memorial Day is the last Monday in May in the US, and Mental Health Awareness runs the whole month there. 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 May content?
Four to six weeks covers most May dates: long enough to brief creative, get approvals and build the supporting email. Give the Mother's Day email an opt-out and build it a month ahead. Anything involving paid media or stock needs longer.
Where are the other months?
Every month has its own page. The previous one is April and the next is June. 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.
