Cron Expression Format

A cron expression consists of 5 fields separated by spaces:

Minute (0-59) — which minute of the hour to run
Hour (0-23) — which hour of the day to run (24-hour format)
Day of Month (1-31) — which day of the month to run
Month (1-12) — which month to run
Day of Week (0-6) — which day of the week to run (0 = Sunday)

Special characters:

* — matches every possible value for that field
*/N — matches every N-th value (e.g. */5 in minute = every 5 minutes)
1,5,10 — matches specific values (comma-separated list)
1-5 — matches a range of values (e.g. 1 through 5)
