How to calculate
Counts the days from today, or any date you choose, to the next August 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 319 days until August 15 on Sunday, August 15, 2027.
Method: Find the first August 15 on or after the start date, then count the days from the start date to it.
- August 15 comes every year, so the count is never more than 365 days.
- The start date itself is not counted: from the day before August 15, the count is 1; on August 15 itself, it is 0.
- Start dates from January 1, 1900 to December 31, 2400 work for the count to August 15, the range the date field accepts.
- Today is the date on your own device, so the count to August 15 changes at midnight where you are. Dates are whole calendar days, so a daylight-saving change never adds or loses a day.
