Script Jobs allow you to run your own code at regular intervals. Some examples are:
Deactivate particular users on a specific date
Get a daily email summary of all pull requests that have been merged in a particular repository/project
The Jobs page displays a list of all configured jobs on the current Bitbucket instance. Click Create Job to configure a custom scheduled job and/or built-in scheduled jobs.
Most jobs take a cron expression to define the interval a job is run at.
If you’re unfamiliar with cron expressions we recommend you use the Cron Maker resource to help you build your own.
