How to calculate
Counts the days from today, or any date you choose, to the next October 31, 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 31 days until October 31 on Saturday, October 31, 2026.
Method: Find the first October 31 on or after the start date, then count the days from the start date to it.
- October 31 comes every year, so the count is never more than 365 days.
- The start date itself is not counted: from the day before October 31, the count is 1; on October 31 itself, it is 0.
- Start dates from January 1, 1900 to December 31, 2400 work for the count to October 31, the range the date field accepts.
- Today is the date on your own device, so the count to October 31 changes at midnight where you are. Dates are whole calendar days, so a daylight-saving change never adds or loses a day.
