What United Nations Day is
Marks the day in 1945 when the UN Charter came into force, having been ratified by the five permanent Security Council members and a majority of the other signatories.
It is a public holiday in a handful of countries and a working observance almost everywhere else.
When it falls, and why the date moves
The countdown at the top of this page is live, and the date beneath it is the next occurrence. This is a fixed date: it falls on the same day of the month every year, so only the weekday changes.
It is grouped here under Observance, alongside the other observances that share its calendar.
What is coming up next
Once this date passes, the countdown moves straight on to the next occurrence — you do not need a different page for next year. See the full list of upcoming events, or use the countdown timer for a date of your own.
