FAQ

Frequently Asked Questions

What is a cron expression?

A cron expression is a string of 5 (or 6) fields separated by spaces that represents a schedule. It's used to schedule periodic tasks in Unix-like systems and cloud schedulers.

What does each field mean?

From left to right: Minute (0-59), Hour (0-23), Day of Month (1-31), Month (1-12), Day of Week (0-6, where 0=Sunday). An asterisk (*) means 'every'.

Can I schedule tasks to run multiple times?

Yes! You can specify multiple values (comma-separated), ranges (with hyphens), or step values (with slashes) to create complex schedules.
