How to calculate
Counts the days from today, or any date you choose, to the next March 12, with its day of the week.
Example with the default inputs (Count from September 30, 2026) on the example date Wednesday, September 30, 2026: From September 30, 2026, there are 163 days until March 12 on Friday, March 12, 2027.
Method: Find the first March 12 on or after the start date, then count the days from the start date to it.
- March 12 comes every year, so the count is never more than 365 days.
- The start date itself is not counted: from the day before March 12, the count is 1; on March 12 itself, it is 0.
- Start dates from January 1, 1900 to December 31, 2400 work for the count to March 12, the range the date field accepts.
- Today is the date on your own device, so the count to March 12 changes at midnight where you are. Dates are whole calendar days, so a daylight-saving change never adds or loses a day.
