Result
How it is calculated
- Each field accepts *, lists (1,15), ranges (1-5), steps (*/10) and English names (JAN, MON).
- When both day-of-month and day-of-week are restricted, either one matching is enough, as in standard cron.
- Next runs are computed in your device’s time zone.
Example
0 9 * * 1-5 runs at 9:00 Monday to Friday.
Good to know
- The 6-field format (seconds) and extensions such as L, W or # are not supported.
- The server running the job may use another time zone.
