Cron Expression Parser
Translate 5-field cron into plain English and see the next scheduled runs.
How it works
Cron has five fields: minute, hour, day-of-month, month and day-of-week. This tool expands lists (1,15), ranges (9-17), steps (*/15) and names (mon-fri), then explains the schedule in words and calculates the next runs.
Example: */15 9-17 * * mon-fri means every 15 minutes during hours 9 to 17, Monday through Friday. When both day-of-month and day-of-week are set, standard cron runs on either match, and the result says so.
