How it works
Cron is a time-based job scheduler used in Unix-like systems. Cron expressions have 5 fields: minute (0-59), hour (0-23), day of month (1-31), month (1-12), and day of week (0-7, where 0 and 7 are Sunday). Special characters include * (any), / (every), - (range), and , (list). This tool parses the expression and describes it in plain English.
