How to calculate
Counts the days from today, or any date you choose, to the next April 15, 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 197 days until April 15 on Thursday, April 15, 2027.
Method: Find the first April 15 on or after the start date, then count the days from the start date to it.
- April 15 comes every year, so the count is never more than 365 days.
- The start date itself is not counted: from the day before April 15, the count is 1; on April 15 itself, it is 0.
- Start dates from January 1, 1900 to December 31, 2400 work for the count to April 15, the range the date field accepts.
- Today is the date on your own device, so the count to April 15 changes at midnight where you are. Dates are whole calendar days, so a daylight-saving change never adds or loses a day.
