How to calculate
Counts the days from today, or any date you choose, to the next June 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 261 days until June 18 on Friday, June 18, 2027.
Method: Find the first June 18 on or after the start date, then count the days from the start date to it.
- June 18 comes every year, so the count is never more than 365 days.
- The start date itself is not counted: from the day before June 18, the count is 1; on June 18 itself, it is 0.
- Start dates from January 1, 1900 to December 31, 2400 work for the count to June 18, the range the date field accepts.
- Today is the date on your own device, so the count to June 18 changes at midnight where you are. Dates are whole calendar days, so a daylight-saving change never adds or loses a day.
