Rob -

It depends on the coordinates of the transmitter site. The Commission 
has a program to calculate the average monthly sunrise and sunset 
times for any location, rounded to the nearest quarter hour, and 
those are the times specified on the station license. You can access 
the program at:

To use it you will need the transmitter site coordinates for stations 
of interest to you, and those can be retrieved with AM queries:
