HOW DATES WORK WITH RECURRING SCHEDULES

The start and end dates are the start and end date of the period, not an overall start and end date.

Daily:

Looks at the Start Time and End Time you choose and will ignore the start and end date fields.

Weekly:
Looks at the day of the week from the day you enter. 
Whether you choose  Wednesday 4th May or Wednesday 18th of May, all we use is the “Wednesday”. Same goes for the end date. That’s just the end day of the weekly schedule.

Monthly:
Looks at the day of the month from the day you enter. 
Whether you choose  Wednesday 4th May or Monday 4th of April, all we use is the “4th”. Same goes for the end date. That’s just the end day of the monthly schedule.
