Frequently Asked Questions

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. It is used in Unix-like systems to schedule recurring tasks.
What do the 5 fields represent?▾
Minute (0-59), Hour (0-23), Day of month (1-31), Month (1-12 or JAN-DEC), Day of week (0-7, where 0 and 7 are Sunday, or SUN-SAT).
What special characters are supported?▾
* (any value), , (list separator), - (range), / (step). For example, */5 means every 5 units, 1-5 means 1 through 5, and 1,3,5 means at 1, 3, and 5.
Is my data secure?▾
Yes, all parsing runs in your browser. No data is sent to any server.
Does this support 6-field or 7-field cron?▾
