How It Works

How the Cron Calculator works

Inputs used

Enter Cron expression, From date, and From time. Those values let the page parse a cron expression and preview the next scheduled run times in your local timezone.

Calculation method

The cron calculator breaks the schedule into five fields: minute, hour, day of month, month, and day of week.

Starting from the reference date and time you enter, it moves forward minute by minute and returns the first future timestamps that satisfy every active cron rule.

What the result means

The main result shown here is next run. The calculator also returns following run, third run, timezone, and normalized so you can review the most useful supporting numbers at the same time.
