Time tools: cron expressions and schedules
Cron expressions, schedules and next run times.
Cron schedules run backups, reports, cache refreshes and cleanup jobs on servers, in Kubernetes CronJobs and in CI pipelines. The syntax is compact — five fields for minute, hour, day of month, month and day of week — and easy to get wrong: a star in the wrong column turns an hourly job into one that runs sixty times an hour.
The generator explains any expression in plain English and lists the next run times, either in UTC, which most servers use, or in your local time zone. Pages for common schedules add variants and the pitfalls people actually run into, such as daylight saving time and the day-of-month versus day-of-week rule.
Everything is computed in your browser, so you can check a schedule before it ships without pasting it anywhere else.
