Availability Escort

How to let user choose time from 8 PM to 6AM or 7 AM . I have only option to select if from is 8 PM to only 11:30 PM the time after is disabled. I tried both 12 and 24 time format and both have same problem. (SAMPLE Escort user may want to select availability for Saturday from 8 PM to 6 AM next morning and availability for Sunday from 7 PM to 3 AM but now can select to only to 11:30 for current day and can't select Sunday from midnight to 6 AM and than again from 7 PM to midnight)
