Cron Parser

A cron expression is a compact five- or six-field schedule format (minute, hour, day of month, month, day of week, sometimes seconds) that's hard to read at a glance. This tool translates it into plain language and lists the next run times in your chosen timezone.

How to use it

• Paste a cron expression (e.g. 0 3 * * * or a shorthand like @daily) and a plain-language schedule description appears instantly.
• The list of upcoming runs shows exact dates and times in your chosen timezone — handy for checking whether a job collides with another.
• Both 5-field cron expressions (standard Unix cron) and 6-field ones with seconds (Quartz and similar schedulers) are supported.

Common uses

• Checking a job's schedule before deploying — confirming the cron expression really runs the script when intended.
• Debugging a job that fires more or less often than expected.
• Building a new cron schedule without looking up the syntax reference every time.

Things to keep in mind

In classic cron, the day-of-month and day-of-week fields combine with OR rather than AND when neither is "*" — a frequent cause of unexpected extra runs.

The server running cron may be set to a different timezone than the one you're assuming — always confirm which timezone the schedule is interpreted in.
