Visual Cron Expression Builder

A cron expression is a string of five fields that specifies a schedule for running recurring tasks. The fields represent: minute (0-59), hour (0-23), day of month (1-31), month (1-12), and day of week (0-6, Sunday=0). Special characters include * (any), , (list), - (range), and / (step).

*/5 means "every 5th value" within the valid range. In the minute field, */5 means every 5 minutes (0, 5, 10, 15, ...). The */N syntax is a shorthand for a step value and is equivalent to writing 0-59/5.

Yes. This tool generates standard 5-field cron expressions compatible with Linux crontab, systemd timers, and most scheduling systems. Some systems also support a 6th field for seconds, but that is not covered here.
