Cron Parser

Paste a cron expression to see what it means in plain English and when it will fire next. Supports standard five-field syntax and the common @hourly / @daily / @weekly / @monthly / @yearly aliases.

Next-run times are computed in your local time zone using your browser's clock.

Day-of-month and day-of-week interact

POSIX-style cron evaluates day-of-month and day-of-week with an OR rule when both are restricted. For example 0 12 1 * 1 fires at noon on the 1st of every month and every Monday — not only Mondays that fall on the 1st. If you want “only Mondays that are the 1st”, you have to filter inside the job.

FAQ

What does 0 12 1 * 1 mean?

Noon on the 1st of every month or noon every Monday. Standard cron treats day-of-month and day-of-week as OR when both are restricted.

Why is */5 * * * * not exactly every 5 minutes?

It is — but it always lands on minutes that are multiples of 5 (0, 5, 10, ...), not on offsets from when you started the job. */5 means “values divisible by 5 within the field range”.

Are seconds supported?

Not in this parser. Standard Unix cron has five fields and no seconds. Some schedulers (Quartz, Spring) add a sixth seconds field — paste those into a parser that supports the six-field flavor.

Which time zone are the next runs in?

Your browser's local time zone. The label above the list shows the zone offset for clarity.
