Server Script - Scheduler Event - Event Frequency

Is there any place in the documentation. Where that these Event Frequency are explained?
What time of the day they run?
what is the difference between Long and regular?

Long - this will add this to the Sheduler Long queue (it is used for jobs that are expected to run for a long time)

By default most of the Daily jobs run at mid-night (12:00 AM)

Thanks for the reply
Which day of the week?
Which day of the month?
It would be good if you could specify those parameters
