Frequently Asked Questions
A cron expression is a string of 5 fields that defines a schedule for automated tasks. The fields represent: 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).
An asterisk (*) means 'every' for that field. For example, '* * * * *' runs every minute. You can also use ranges (1-5), lists (1,3,5), and step values (*/15 for every 15 minutes).
