About May 18
May 18 is the 138th day of the year in the Gregorian calendar (139th 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 18 is a fixed annual date: it occurs on the same calendar date every year and is always 1 day after May 17 and 1 day before May 19. That makes the countdown predictable for seasonal events and deadlines.

How the countdown works
We create May 18 at 00:00 in your local timezone for this year. If that moment has already passed, we roll to May 18 next year.
All calculations use your device clock and local timezone, so the countdown hits zero exactly when May 18 starts where you are.
Remaining milliseconds are converted to days, hours, minutes, and seconds. Values never go negative and update every second.
Leap years are handled automatically by the calendar — the interval from May 18 to next May 18 is 365 or 366 days as appropriate.
If today is after May 18, the timer counts toward next year’s May 18 and shows how many days ago the last one occurred.
The timer is scoped to this component, accessible, and works on mobile without external libraries.
