This tool takes a cron expression and computes the next several times it will actually run, so you can confirm a schedule does what you intend before deploying it. The calculation happens live in your browser.
How to use it
- Enter a cron expression (five fields).
- The next upcoming run times are listed.
- Adjust the expression and watch the times update.
- Confirm it matches your intent before shipping.
About Cron Next Runs
Reading a cron expression tells you the rule; seeing the next run times tells you the reality. The two can diverge in surprising ways — a schedule you thought ran nightly might fire far more often, or skip the day you expected. By projecting the actual upcoming execution timestamps, this tool turns an abstract pattern into concrete dates you can sanity-check. It is the natural companion to writing or reviewing a scheduled job, and it runs entirely client-side.
