How to calculate
Counts the days from today, or any date you choose, to May 1, the first day of the next May, with its weekday and the time in weeks and months.
Example with the default inputs (Count from September 30, 2026) on the example date Wednesday, September 30, 2026: From September 30, 2026, there are 213 days until May on Saturday, May 1, 2027.
Method: Find the first May 1 on or after the start date, then count the days from the start date to it.
- The count is to May 1, the first day of the month. During May, it counts to May 1 of the next year.
- The start date itself is not counted: from the day before, the count is 1; on the day itself, it is 0.
- Dates are calendar days with no time of day, so a time zone or a daylight-saving change never adds or loses a day.
- Start dates from January 1, 1900 to December 31, 2400 work.
