About April 21
April 21 is the 111th day of the year in the Gregorian calendar (112th in a leap year), situated in mid-spring in the Northern Hemisphere. It falls in the second quarter of the year, often associated with spring renewal, tax deadlines, and Easter-season planning.
The name April comes from the Latin aperire, meaning “to open,” referring to the opening of buds and blossoms in spring. In the early Roman calendar April was the second month.
For planning today, April 21 is a fixed annual date: it occurs on the same calendar date every year and is always 1 day after April 20 and 1 day before April 22. That makes the countdown predictable and useful for quarterly deadlines, spring events, and academic calendars.

How the countdown works
We create April 21 at 00:00 in your local timezone for this year. If that moment has already passed, we roll to April 21 next year.
All calculations use your device clock and local timezone, so the countdown hits zero exactly when April 21 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 April 21 to next April 21 is 365 or 366 days as appropriate.
If today is after April 21, the timer counts toward next year’s April 21 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.
