FAQ
What is a cron expression?
A cron expression is a string of 5 fields (minute, hour, day-of-month, month, day-of-week) that defines a schedule. Example: '0 9 * * 1' runs at 9 AM every Monday.
What does * mean in cron?
An asterisk ( ) means 'every value' for that field. So ' * * * *' runs every minute of every hour of every day.
Can I use ranges and steps?
Yes. Use ranges (1-5), steps (_/5 for every 5), and lists (1,3,5). Example: '0 _/2 * * *' runs every 2 hours.
