Fields accept numbers, *, lists (1,15), ranges (9-17), steps (*/10) and names (MON-FRI, JAN). When both day fields are set, standard cron runs on either one.
Cron Expression Generator
Cron schedules are five fields (minute, hour, day of month, month and day of week) that are easy to get subtly wrong. Build an expression field by field or paste one to check it: the tool describes it in plain English, flags mistakes, and lists the next run times in your time zone. Common schedules are one click away.
How to use Cron Expression Generator
- Pick a common schedule, or edit the five fields.
- Read the plain-English description and check the next run times.
- Copy the expression into your crontab, scheduler or CI configuration.
When it comes in handy
- Scheduling backups, reports and cron jobs on a server.

Frequently asked questions
- What does */15 mean?
- Every 15 units starting from the lowest value: */15 in the minute field runs at minutes 0, 15, 30 and 45.
- Which time zone does cron use?
- Usually the server's time zone, which is often UTC. The next runs here are shown in your browser's time zone, so allow for any difference.
- What if I set both day of month and day of week?
- Standard cron runs the job when either matches, not only when both do. The tool accounts for this.
