About this date
About May 31
May 31 is the 151st day of the year in the Gregorian calendar (152nd in a leap year), situated in late spring in the Northern Hemisphere. It falls in the second quarter, a period linked to spring festivals, academic finals, and early summer planning.
The name May comes from the Latin Maius, traditionally linked to Maia, the Roman goddess of growth, reflecting spring abundance in the Northern Hemisphere.
For planning today, May 31 is a fixed annual date: it occurs on the same calendar date every year and is always 1 day after May 30 and 1 day before June 1. That makes the countdown predictable for seasonal events and deadlines.

How the countdown works
1. Next occurrence
We create May 31 at 00:00 in your local timezone for this year. If that moment has already passed, we roll to May 31 next year.
2. Local time only
All calculations use your device clock and local timezone, so the countdown hits zero exactly when May 31 starts where you are.
3. Days → seconds
Remaining milliseconds are converted to days, hours, minutes, and seconds. Values never go negative and update every second.
4. Leap years
Leap years are handled automatically by the calendar — the interval from May 31 to next May 31 is 365 or 366 days as appropriate.
5. Already passed?
If today is after May 31, the timer counts toward next year’s May 31 and shows how many days ago the last one occurred.
6. Responsive & scoped
The timer is scoped to this component, accessible, and works on mobile without external libraries.
