Cron Expression Explainer — FAQs
What is a cron expression?
A cron expression is a 5-field schedule string (minute, hour, day of month, month, day of week) that tells servers when to run automated jobs — backups, reports, cleanups and more.
What do the 5 cron fields mean?
In order: minute (0-59), hour (0-23), day of month (1-31), month (1-12), day of week (0-7, where both 0 and 7 mean Sunday). An asterisk means every value.
What does */15 * * * * mean?
Every 15 minutes, every hour, every day. The */n syntax means every nth unit — one of the most common cron patterns for frequent jobs.
Is the cron explainer free?
Yes — paste any standard 5-field cron expression and get the plain-English explanation instantly, no signup needed.
