How to calculate

Counts the days from today, or any date you choose, to the next January 12, 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 104 days until January 12 on Tuesday, January 12, 2027.

Method: Find the first January 12 on or after the start date, then count the days from the start date to it.

  • January 12 comes every year, so the count is never more than 365 days.
  • The start date itself is not counted: from the day before January 12, the count is 1; on January 12 itself, it is 0.
  • Start dates from January 1, 1900 to December 31, 2400 work for the count to January 12, the range the date field accepts.
  • Today is the date on your own device, so the count to January 12 changes at midnight where you are. Dates are whole calendar days, so a daylight-saving change never adds or loses a day.
