How to calculate

Counts the days from today, or any date you choose, to the next July 21, 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 294 days until July 21 on Wednesday, July 21, 2027.

Method: Find the first July 21 on or after the start date, then count the days from the start date to it.

  • July 21 comes every year, so the count is never more than 365 days.
  • The start date itself is not counted: from the day before July 21, the count is 1; on July 21 itself, it is 0.
  • Start dates from January 1, 1900 to December 31, 2400 work for the count to July 21, the range the date field accepts.
  • Today is the date on your own device, so the count to July 21 changes at midnight where you are. Dates are whole calendar days, so a daylight-saving change never adds or loses a day.
