Cron Expression Parser — A cron expression is a compact way to describe a recurring schedule. The classic format has five fields: minute, hour, day of month, month, and day of week. Each field can be a wildcard (*), a single value, a list (1,15,30), a range (9-17), or a step (*/15, 9-17/2).
Parsing runs locally in your browser. No expression is sent to a server.

A cron expression is a compact way to describe a recurring schedule. The classic format has five fields: minute, hour, day of month, month, and day of week. Each field can be a wildcard (*), a single value, a list (1,15,30), a range (9-17), or a step (*/15, 9-17/2).
Paste any cron expression and the tool breaks it down field by field, shows you the next five times it will fire (in UTC), and gives you a plain-English summary so you can sanity-check what you wrote.
