A cron expression is a string of characters that defines a schedule for a "cron job," which is an automated task that runs at a specific time or interval on Unix-like computer operating systems. The expression consists of five fields (Minute, Hour, Day of Month, Month, Day of Week) that tell the system precisely when to execute a command or script.
┌───────────── minute (0 - 59) │ ┌───────────── hour (0 - 23) │ │ ┌───────────── day of the month (1 - 31) │ │ │ ┌───────────── month (1 - 12) │ │ │ │ ┌───────────── day of the week (0 - 6) (Sunday to Saturday) │ │ │ │ │ │ │ │ │ │ * * * * ** (Asterisk): Represents "every". An asterisk in the Hour field means the task will run every hour., (Comma): Used to specify a list of values. For example, 1,15,30 in the Minute field means the task runs at 1, 15, and 30 minutes past the hour.- (Hyphen): Defines a range of values. 1-5 in the Day of Week field means the task runs from Monday to Friday./ (Slash): Specifies step values. */15 in the Minute field means "every 15 minutes."Continue your workflow with tools from this category and other useful options.
