Cron Expression Parser

What is Cron?

Cron is a time-based job scheduler commonly used in Unix-like operating systems. It allows you to schedule scripts or commands to run automatically at specified intervals. You can learn more about Cron’s history and usage on Wikipedia.

Understanding Cron Expressions

A cron expression is a string that represents a schedule. It typically has five fields, which represent:

• Minute: The minute the job should run (0 - 59).
• Hour: The hour the job should run (0 - 23).
• Day of Month: The day of the month to run the job (1 - 31).
• Month: The month to run the job (1 - 12).
• Day of Week: The day of the week to run the job (0 - 6, where 0 is Sunday).

• Minute: The minute the job should run (0 - 59).
• Hour: The hour the job should run (0 - 23).
• Day of Month: The day of the month to run the job (1 - 31).
• Month: The month to run the job (1 - 12).
• Day of Week: The day of the week to run the job (0 - 6, where 0 is Sunday).

Example Cron Expression

For example, the following cron expression:

0 12 * * MON

will run every Monday at 12:00 PM.

More Example Usages

• Run a job every minute: * * * * * (This runs the job every minute of every hour, every day.)
• Run a job every day at 3 AM: 0 3 * * * (This runs the job at 3:00 AM every day.)
• Run a job every Friday at 5 PM: 0 17 * * FRI (This runs the job at 5:00 PM every Friday.)
• Run a job on the 1st of every month at midnight: 0 0 1 * * (This runs the job at midnight on the first day of every month.)
• Run a job every hour at 15 minutes past the hour: 15 * * * * (This runs the job at 15 minutes past every hour.)
