Frequently Asked Questions

What is a cron expression? +

A cron expression is a 5-field time specification used to schedule recurring jobs. Fields are: minute (0–59), hour (0–23), day-of-month (1–31), month (1–12), day-of-week (0–6, Sunday=0).

What special characters are supported? +

* = every value, */n = every nth value, a-b = range, a,b,c = list of values.

Are timezone offsets supported? +

Next run times are calculated in your browser's local timezone. Standard cron itself has no timezone field β€” timezones are configured at the scheduler level (e.g., crontab TZ= prefix).
