Frequently Asked Questions — Cron Expression Parser
What is a cron expression?
A cron expression is a string of five or six fields that defines a recurring schedule. The fields represent minute, hour, day of month, month, and day of week. For example, "0 9 * * 1-5" means "at 9:00 AM every weekday." Cron is widely used in Unix/Linux systems and job schedulers.
What do the special characters mean in cron?
The asterisk (*) means every value, the comma (,) separates multiple values, the hyphen (-) defines a range, and the slash (/) defines step intervals. For example, */5 in the minute field means every 5 minutes, and 1-5 in the day-of-week field means Monday through Friday.
Does it support seconds and year fields?
Yes. The tool supports both standard 5-field cron (minute through day-of-week) and extended formats with a seconds field and a year field. Select the appropriate format from the options to match your cron implementation.
