SMS Schedule Example 7

Current Date: 19th April
Appointment Date: 26th, 27th April
Selected Intervals: 2 days, 7 days
Do not send on closed/absent days? False (not selected)
Result: SMS messages are sent on 19th April for appointments on 26th April
Explanation: The appointment on the 26th is included because the 7-day interval is selected, and the 19th is 7 days prior to these appointments.

The appointment on the 27th is 8 days away, so it falls outside the 7-day interval. Because SMS messages can be sent in the closed/absent days, the SMS for the appointments on the 27th will be picked up on the 20th.
