How to calculate
Counts the days from today, or any date you choose, to the next March 17, 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 168 days until March 17 on Wednesday, March 17, 2027.
Method: Find the first March 17 on or after the start date, then count the days from the start date to it.
- March 17 comes every year, so the count is never more than 365 days.
- The start date itself is not counted: from the day before March 17, the count is 1; on March 17 itself, it is 0.
- Start dates from January 1, 1900 to December 31, 2400 work for the count to March 17, the range the date field accepts.
- Today is the date on your own device, so the count to March 17 changes at midnight where you are. Dates are whole calendar days, so a daylight-saving change never adds or loses a day.
