How to calculate
Counts the days from today, or any date you choose, to the next January 20, 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 112 days until January 20 on Wednesday, January 20, 2027.
Method: Find the first January 20 on or after the start date, then count the days from the start date to it.
- January 20 comes every year, so the count is never more than 365 days.
- The start date itself is not counted: from the day before January 20, the count is 1; on January 20 itself, it is 0.
- Start dates from January 1, 1900 to December 31, 2400 work for the count to January 20, the range the date field accepts.
- Today is the date on your own device, so the count to January 20 changes at midnight where you are. Dates are whole calendar days, so a daylight-saving change never adds or loses a day.
