Use the still tool

Turn vague time and frequency language into dates, intervals and repeatable schedules.

What still.so is for

The name emphasizes context: explain how the time expression changes the result.

Keep the date and time zone visible

A clock reading or duration can cross midnight. Include the calendar date, UTC offset and named time zone whenever a result will be shared.

Check the result before sharing

Confirm the calendar date, local clock time, UTC offset and named time zone so another person can reproduce the same result.
