"Triggering a Plan build based on a schedule" can allow a team to structure the day according to a predictable schedule. Note that scheduled builds are run regardless of whether or not any code changes have occurred. There are two ways to schedule a build:
The schedule can be daily (times per day), weekly (days per week), monthly (days per month) or based on a Cron expression.
See Cron Based Scheduling.You can also trigger builds based on code changes or manually, rather than on a schedule.
