Making time changes on certain days
For me, Friday is a half day (where I end at 1 pm instead of 3:10), and my classes are shorter. Normally, they are 80 minutes, but on Friday, they are 60 minutes. I would like a function where the schedule adapts to a certain day (change the original time to the adapted time).
If any of you don't understand, don't be afraid to ask for me to clarify!
