Cron Expression Syntax

A cron expression has 5 fields: minute (0-59), hour (0-23), day of month (1-31), month (1-12), and day of week (0-7, where 0 and 7 are Sunday). Special characters: * (any), , (list), - (range), / (step). Cron jobs are used in Unix/Linux for scheduling automated tasks like backups, log rotation, and system maintenance.

* — any value
5,10 — list (5 and 10)
1-5 — range (1 to 5)
*/15 — step (every 15)
0 — Sun, 1 — Mon ...
1-12 — Jan to Dec
