Frequently Asked Questions

What is a cron expression?
A cron expression is a string of 5 fields representing minute, hour, day of month, month, and day of week. It defines when a scheduled task should run.
What does the asterisk (*) mean?
An asterisk means 'every' or 'any value'. For example, * in the hour field means the task runs every hour.
How do I run a task every 5 minutes?
Use */5 in the minute field: */5 * * * *. The /5 syntax means 'every 5 units'.
What's the difference between day fields?
Day of month (1-31) specifies the calendar date, while day of week (0-6) specifies which weekday (0=Sunday).
Are cron expressions timezone-aware?
Cron expressions use the server's timezone by default. Check your server or platform documentation for timezone configuration.
