Cron field cheat sheet

Day of Month

Month

Day of Week

Minute is always the first field. Day of week uses 0 for Sunday and 6 for Saturday.

Common patterns

*/5 * * * * — every five minutes
0 0 * * 0 — every Sunday at midnight
0 9 * * MON-FRI — weekdays at 09:00
0 0 1 * * — first day of every month
0 */6 * * * — every six hours

Cron expressions always use the server timezone. Double-check that your cron daemon runs with the expected timezone, or convert the schedule to UTC before applying it to production systems.
