Cron Next Run Calculator
Use the fields above to transform, validate, or format input. Errors appear in the on-page alert when parsing fails.
Cron next run (UTC)
Five fields: minute hour day-of-month month day-of-week. Supports numbers, *, and */n for minute/hour. Search starts after reference time.
How this is calculated
We step forward one minute at a time in UTC from just after the reference instant until the five cron fields all match or a one-year cap is hit. Only numeric fields, *, and */n for minute and hour are supported reliably.
