┌───────────── 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, 7 = Sunday) │ │ │ │ │ * * * * *
Special characters

Day-of-month and day-of-week together
When both day fields are restricted, standard cron runs the job if either one matches. 0 0 13 * 5 runs on the 13th of every month and on every Friday, not only on Friday the 13th.
Time zones
Cron runs in the server's time zone. Next runs here are shown in your browser's time zone. AWS EventBridge and many CI tools use UTC, and AWS also uses a 6-field format with a year.
