FAQ
What are the 5 cron fields?
From left to right: minute (0-59), hour (0-23), day of month (1-31), month (1-12), day of week (0-6, 0=Sunday).
What does the asterisk (*) mean?
The asterisk means "all values". For example, in the hour field, * means every hour.
How do steps work?
Use / for steps. For example, */5 means every 5 units. In the minute field, this means every 5 minutes.
Can this tool replace crontab?
This tool only edits and validates cron expressions. It does not modify your system crontab. Copy the generated expression to use in crontab.
