How the Days Until Counter counts

The Days Until Counter subtracts today's date from the date you enter and shows the number of whole calendar days left, such as 49 days until 2026-12-25 when today is 2026-11-06. Both dates are taken at midnight UTC, so the count changes once a day at 00:00 UTC.

If the date is today, the result reads Today is, and a date in the past is counted as days since instead. A date with a time zone offset is converted to UTC first, which can move it to the previous or next day.
