Cron Expression Parser
Parse standard 5-field cron expressions and see the schedule in plain English plus the next few run times in your local time zone. Validate the expression with clear error messages.
Type a standard cron like '*/5 * * * *' and the tool expands each field into the times it fires: every 5 minutes, daily at 2:30, etc. Next-run computations account for the current date.

Standard 5-field cron (minute hour day-of-month month day-of-week); a 6-field expression is read as seconds plus the five standard fields. When both day fields are restricted, cron's OR rule applies — a run matches if either day-of-month or day-of-week matches. Computations run locally against your device clock.
