Cron Expression Builder

Build a 5-field cron schedule from presets and dropdowns, or paste an existing expression into the box to decode it. You get a plain-English explanation and the next 5 run times, live.

Preset:

Minute

Hour

Day of month

Month

Day of week

Cron expression (editable - paste an existing one here to decode it)

Next 5 run times

Interpret in UTC (how GitHub Actions runs it)

#	Run time (your local timezone)	Relative

Field order: minute (0-59), hour (0-23), day of month (1-31), month (1-12 or JAN-DEC), day of week (0-6 or SUN-SAT, where 0 and 7 both mean Sunday). When both day-of-month and day-of-week are restricted, classic cron runs when either one matches. GitHub Actions runs cron in UTC (and schedules can fire a few minutes late on busy runners), so tick the UTC box above when planning workflow schedules. This tool supports the standard syntax: *, values, lists, ranges, and steps; extensions like L, W, and # are not standard and are not supported here.
