About Cron Expressions & Syntax

A Cron expression is a string consisting of five or six fields separated by white space that represents a schedule. Traditional Linux/Unix crontab entries utilize five parameters:

*   *   *   *   *
│   │   │   │   │
│   │   │   │   └─ Day of week (0 - 6) (0 is Sunday)
│   │   │   └───── Month (1 - 12)
│   │   └─────── Day of month (1 - 31)
│   └───────── Hour (0 - 23)
└─────────── Minute (0 - 59)

Special characters:

  • * (Asterisk): Represents all values. * in the Minute field means "execute every minute".
  • / (Slash): Represents increments. */5 in the Minute field means "every 5 minutes".
  • , (Comma): Separates list items. 1,3,5 in Day of Week means "Mon, Wed, and Fri".
  • - (Hyphen): Defines range. 0-9 in Hours means "from midnight to 9 AM".
