About March 12
March 12 is the 60th day of the year in the Gregorian calendar (61st in a leap year), marking the traditional start of meteorological spring in the Northern Hemisphere. It sits at the transition from winter to spring, which is why many seasonal schedules, school terms, and fiscal planning cycles reference it.
Historically, March was the first month in the early Roman calendar — hence the name from Martius (Mars) — before January and February were added. March 12 therefore carried New Year significance in ancient Rome, but in the modern Gregorian calendar the year begins on January 1.
For planning today, March 12 is a fixed annual date: it occurs on the same calendar date every year and is always 1 day after March 11 and 1 day before March 13. That makes the countdown predictable and useful for quarterly deadlines, spring launches, and academic calendars.

How the countdown works
We create March 12 at 00:00 in your local timezone for this year. If that moment has already passed, we roll to March 12 next year.
All calculations use your device clock and local timezone, so the countdown hits zero exactly when March 12 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 March 12 to next March 12 is 365 or 366 days as appropriate.
If today is after March 12, the timer counts toward next year’s March 12 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.
