How to use
- Read the expression and the English meaning above. Confirm they match the job you have in mind.
- Use the time zone dropdown to preview the next 10 fire times in UTC or a US/EU city.
- Copy the expression into crontab, GitHub Actions (`on.schedule.cron`), or your job runner.
- If you need a nearby interval, browse the related schedules at the bottom of this page.
Daily midnight is the default for “do this once a day.” Minute 0, hour 0, any date. The only hard part is whose midnight: the server’s TZ, UTC, or the business’s city.
A job that is supposed to close a US East business day often wants 0 0 * * * in America/New_York, not UTC. Preview the next runs in the zone you care about before you ship.
When this schedule is a good fit
Typical uses: Nightly warehouse extracts; Rotating access logs; Resetting a daily quota counter.
Cron fields are zone-naive. The daemon’s TZ — or the TZ= line above the job — decides what “midnight” or “9am” means. Preview both UTC and the office zone before you ship.
