Reading the five fields
A standard cron expression has five fields: minute, hour, day-of-month, month and day-of-week. Symbols like * (every), */n (every n) and ranges (1-5) combine to describe a schedule. Getting one field wrong can mean a job runs far more — or less — often than intended.
Type an expression and the description updates live, so you can tweak a field and immediately see the effect.
