What is a cron expression?
A cron expression is the five-field schedule used by Unix/Linux crontab, database jobs, CI pipelines and countless schedulers to say when a task should run. The five fields are minute, hour, day-of-month, month, and day-of-week. This tool translates any expression into plain English, shows exactly what each field means, and lists the next times it will fire — all in your browser, nothing uploaded.
Frequently Asked Questions
What do the five fields mean?
In 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). * means “every”.
What symbols can I use?
* every value, */5 every 5th, 1-5 a range, 1,15,30 a list, and combinations like 0-30/10. Shortcuts @yearly @monthly @weekly @daily @hourly are also supported.
Why does “day of month” AND “day of week” behave oddly together?
Standard cron uses OR when both are set: 0 0 13 * 5 runs on the 13th or any Friday, not only Friday the 13th. This tool follows that rule and says so in the summary.
What timezone are the next-run times in?
Your device’s local timezone (shown below the list). Servers usually run cron in UTC or the server’s timezone, so double-check where the job actually runs.
