How to calculate

Counts the days from today, or any date you choose, to the next February 18, 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 141 days until February 18 on Thursday, February 18, 2027.

Method: Find the first February 18 on or after the start date, then count the days from the start date to it.

  • February 18 comes every year, so the count is never more than 365 days.
  • The start date itself is not counted: from the day before February 18, the count is 1; on February 18 itself, it is 0.
  • Start dates from January 1, 1900 to December 31, 2400 work for the count to February 18, the range the date field accepts.
  • Today is the date on your own device, so the count to February 18 changes at midnight where you are. Dates are whole calendar days, so a daylight-saving change never adds or loses a day.
