How it works

The five fields are minute, hour, day of month, month and day of week. The parser explains each field separately, expanding step values, ranges and lists into readable names.

Frequently asked questions

What does */5 mean?

Every five units of that field — so */5 in the minute column runs twelve times an hour.

Is Sunday 0 or 7?

Both work in most cron implementations; 0 is the portable choice.
