Hi All,

Trying not to reinvent a wheel here. I am creating an app for a child learning center. Each child can be entered into a several programs that the center offers. Each program has a schedule, i.e. PT1 meets M,W,F from 10:00 to 10:45, OT2 meets M to F 9:30 to 10:00. I need to figure out if there is a conflict between the programs that are scheduled for a child. I have a child table and a program table. The program table has logical values for each day of the week for when it meets and a from and to time that it meets. The number of programs a child is assigned to varies for each kid. A cross table contains a child id and program id. Any ideas of how to efficiently code whether there is a conflict in a childs schedule? I would need to know whether there is a confilct as well as which two or more programs conflict. Ideally it would be best to account for possibilites of any start and end time, i.e I don't want to make an assumption the start and end times are in 15 or 30 minute increments. Any ideas of to go about this?

Thanks in advance.

Peter
