What is Memorial Day?

Memorial Day is the last Monday in May, honouring Americans who died in military service. Note that the rule is the last Monday, not the fourth: in a May with five Mondays those are different days, which is a common source of wrong dates in hand-written calendars. It began as Decoration Day after the Civil War and moved to a fixed Monday under the Uniform Monday Holiday Act in 1971. The long weekend is treated as the start of the American summer.

The next one falls on Monday, 31 May 2027, and this page counts down to the midnight that starts it in whatever time zone your browser reports. For a date of your own, the deadline countdown takes any target and tracks progress against it.

Frequently asked questions

How is this countdown calculated?

The target is midnight at the start of Monday, 31 May 2027, read in your device's own time zone rather than in a fixed one. Two people opening this page in London and Tokyo see different amounts of time left, because their local midnights are nine hours apart. Nothing is sent anywhere: the clock in your browser does the arithmetic.

What happens once the date has passed?

The page rolls to the next occurrence on its own. Every date here is worked out from a rule rather than looked up in a table, so once Memorial Day is behind you the countdown restarts against the following one without anybody updating the site. If you leave the tab open overnight, it rolls over while you watch.

Why does it read zero on the day itself?

The countdown aims at the beginning of the day rather than at any particular hour of it, so it hits zero at midnight and stays there until the day is over. That is the answer most people want from a question like "how many days until Memorial Day", where the honest reply on the day is none.
