How to calculate
Counts the days from today, or any date you choose, to the next September 14, 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 349 days until September 14 on Tuesday, September 14, 2027.
Method: Find the first September 14 on or after the start date, then count the days from the start date to it.
- September 14 comes every year, so the count is never more than 365 days.
- The start date itself is not counted: from the day before September 14, the count is 1; on September 14 itself, it is 0.
- Start dates from January 1, 1900 to December 31, 2400 work for the count to September 14, the range the date field accepts.
- Today is the date on your own device, so the count to September 14 changes at midnight where you are. Dates are whole calendar days, so a daylight-saving change never adds or loses a day.
