Cron expression

Format: minute hour day-of-month month day-of-week

Update the fields by pasting a 5-part cron expression.

What this runs

  • Minute: Every minute
  • Hour: Every hour
  • Day of month: Every day
  • Month: Every month
  • Day of week: Every weekday

Quick examples

To run every Monday, set day-of-week to 1 and leave day-of-month as *. Use both fields only when you want matches on either calendar rule.

How cron matches

  • Use * for “every” value.
  • Use lists (1,3,5), ranges (9-17), and steps (*/10).
  • If both day-of-month and day-of-week are set, most cron implementations trigger when either field matches.
