How to calculate

Counts the days from today, or any date you choose, to the next June 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 258 days until June 15 on Tuesday, June 15, 2027.

Method: Find the first June 15 on or after the start date, then count the days from the start date to it.

  • June 15 comes every year, so the count is never more than 365 days.
  • The start date itself is not counted: from the day before June 15, the count is 1; on June 15 itself, it is 0.
  • Start dates from January 1, 1900 to December 31, 2400 work for the count to June 15, the range the date field accepts.
  • Today is the date on your own device, so the count to June 15 changes at midnight where you are. Dates are whole calendar days, so a daylight-saving change never adds or loses a day.
