What is the Cron Expression Parser?

The Cron Expression Parser explains a cron schedule in plain English and lists the next five times it will run. Paste an expression such as 0 9 * * 1-5 to confirm it means "at 09:00, Monday through Friday", optionally in a specific time zone, before you put it into crontab, Kubernetes or a CI pipeline.

How to use it

  1. Enter a cron expression.
  2. Read the human-readable description.
  3. Check the next five run times and the time zone.

Features

  • Plain-English description of the schedule
  • Next five run times
  • Time zone support
  • Validation of invalid fields

Frequently asked questions

What do the five cron fields mean?

In order they are minute (0-59), hour (0-23), day of month (1-31), month (1-12) and day of week (0-6, Sunday is 0). An asterisk means every value.

How do I run a job every 15 minutes?

Use */15 * * * *. The parser will confirm it runs at minutes 0, 15, 30 and 45 of every hour.
