Cron Expression Parser / Next Run Times

Enter a 5-field cron expression (min hour day month weekday); this tool validates the syntax instantly and computes the next 6 run times in your local timezone. It supports * , a-b ranges, */n steps, a,b,c lists, and correctly handles cron's classic OR semantics when both day-of-month and day-of-week are set.

Cron is the standard for scheduled jobs (crontab, launchd alike). Note: servers usually run cron in UTC while this tool uses your local timezone — mind the offset when deploying. All local, never uploaded.

Fields: min(0-59) hour(0-23) day(1-31) month(1-12) weekday(0-6, 0/7=Sun)

FAQ

What does 0 9 * * 1-5 mean?

9:00 sharp every weekday (Mon–Fri). Paste it to see the next several exact run times.

What if both day-of-month and day-of-week are set?

Cron's classic semantics use OR — it fires if either matches (e.g. 0 0 13 * 5 = the 13th of any month OR every Friday). This tool implements that correctly.

Are 0 and 7 both Sunday?

Yes. The weekday field 0-6 maps Sunday to Saturday, and 7 also means Sunday; this tool normalizes 7 to Sunday.
