# Cron Expression Parser

> Translate a cron expression into plain English and see when it will next run.

To read a cron expression, paste it above and it is translated into plain English with each field labelled. The five fields are minute, hour, day of month, month and day of week; a six-field expression adds seconds at the front.

## FAQ

### What does */15 mean?

A step value — "every 15 units" within that field. In the minute field it means the job runs at :00, :15, :30 and :45 of every hour.

### Why does my job run twice on some days?

If both day-of-month and day-of-week are restricted, most cron implementations run the job when EITHER matches, not both. Leave one as * unless you want that behaviour.
