Cron Expression Generator & Explainer
Build a crontab schedule from plain controls and read it back in plain English.
Type a cron expression to get a plain-English description and the next run times, or build one with the presets. Standard 5-field crontab syntax.
Runs entirely in your browser — nothing you enter is sent to a server.

Five fields: minute, hour, day-of-month, month, day-of-week. Supports *, ranges (1-5), steps (*/15) and lists (1,15,30). Next-run times are computed in your local timezone.
Heads up
Day-of-month and day-of-week together is an OR, not an AND — a classic production foot-gun.
