A cron expression copied from a config file or a Stack Overflow answer either runs on the schedule someone intended or it doesn't, and five fields of asterisks and numbers packed together give no obvious clue which, especially once a step value or a comma-separated list gets involved. This tool checks whether a cron expression is actually valid, then translates it into a plain-language description and lists the next ten times it would actually run, rather than leaving someone to mentally simulate five cryptic fields.

Useful for confirming a cron expression copied from documentation actually means what it appears to mean, catching a typo in a scheduled job before it ships to production, or checking the next several run times to confirm a job fires exactly when expected rather than five minutes off.

Quick answers for Cron Schedule Checker

How many upcoming run times are shown?
Five, calculated by scanning forward minute by minute from right now until five matches are found.
What happens if I paste an invalid expression?
An inline error names the exact problem, like "Invalid minute field (expected 0-59)" or the wrong number of fields, instead of a generic failure message.
Does it accept shorthand like @daily or @hourly?
Yes, seven named shortcuts are recognized (@yearly, @annually, @monthly, @weekly, @daily, @midnight, @hourly) and expanded to their five-field equivalent automatically.
