Cron expression builder
Paste a five-field cron expression (or pick a preset) to see what it means and exactly when it will run next. Standard cron: minute, hour, day of month, month, day of week.
Field order, for the millionth time
| Field | Allowed | Extras |
|---|---|---|
| minute | 0-59 | * , - / |
| hour | 0-23 | * , - / |
| day of month | 1-31 | * , - / |
| month | 1-12 or jan-dec | * , - / |
| day of week | 0-7 or sun-sat (0 and 7 are Sunday) | * , - / |
The classic trap: when both day-of-month and day-of-week are
restricted, standard cron runs when either matches, not both.
0 0 13 * fri runs every Friday and every 13th, not only
Friday the 13th. Times are the machine's local time; check the server's
timezone before blaming cron.
Scheduled tasks that report back.
Moorfox runs saved commands across your fleet with output and exit codes captured, so the recurring job is a record you can check rather than a cron line you hope is firing.
