How to calculate

Counts the days from today, or any date you choose, to the next Thursday, with its date and the Thursday after it.

Example with the default inputs (Count from September 30, 2026) on the example date Wednesday, September 30, 2026: From September 30, 2026, there is 1 day until Thursday, October 1, 2026.

Method: Days until Thursday = (4 − the start date’s weekday + 7) mod 7, with Sunday = 0, Monday = 1, …, Saturday = 6.

  • On a Thursday, the count is 0; the Thursday after is 7 days away.
  • The start date itself is not counted: from the day before, the count is 1.
  • Dates are calendar days with no time of day, so a time zone or a daylight-saving change never adds or loses a day.
  • Start dates from January 1, 1900 to December 31, 2400 work.
