*/5 means 'every 5' — e.g., */5 * * * * = every 5 minutes

Frequently Asked Questions

What is cron syntax?

Five space-separated fields: minute (0-59), hour (0-23), day of month (1-31), month (1-12), day of week (0-6, Sun=0). Use * for any, */n for intervals, n-m for ranges.

Does this support seconds?

Standard cron uses 5 fields (no seconds). Some systems like Spring and Quartz use 6 fields with seconds first. This tool uses the standard 5-field format.
