Cron Expression Tester
Paste a cron expression and see exactly when it runs next, in whichever timezone your server uses.
Try: */5 * * * * · 0 3 * * * · 0 9 * * 1-5 · 0 0 1 * * · 30 2 * * 0
0 9 * * 1-5
Minute 0, hour 9, day of month any, month any, day of week 1-5.

Times shown in UTC. Cron uses the server's timezone, which is often UTC even when you are not — a common reason a job appears to run at the wrong hour.
Know when a job silently stops running
A schedule that is correct today still fails the night the server reboots. Pingniner heartbeats tell you when a job misses its window, instead of you finding out from the missing backup.
