Enter a cron expression above to see what it means.

Standard 5-field cron, parsed entirely in your browser. Supports lists (1,15,30), ranges (1-5), steps (*/15), month and weekday names, and macros like @daily. When both day-of-month and day-of-week are set, cron runs when either matches — the explanation says so.
