Totally useless..unless you are in UFL

This is the schedule of classes at UFL. Here people say I have class at period 1, I'm free at period 6 etc. I always get confused with the mapping between period and their scheduled timings. I decided to put it here, so I can quickly look  up.

Period 1     7:25                            
Period 2     8:30                            
Period 3     9:35                            
Period 4     10:40                            
Period 5     11:45                            
Period 6     12:50    
Period 7     1:55
