Excel Macro VBA automatic timetable

I need an Excel Macro that can make an automatic weekly timetable for my studies. I want to be able to enter my lecture times and how many hours a week I have to spend on reading/group work/essay writing etc. per module. It would also have to be considered, how many hours a day I would want to work and how much time I have each day. For example, I could enter that I have time to work from 8am to 8pm and would like to work a maximum of 6 hours that day. It should be adaptable for each day. It also has to be considered if I want to have one or two days off. Small breaks in between tasks and a longer lunch break also should be considered. It would be optimal if recurring events like lecture only have to be entered once. When having entered everything I would like to get a timetable that spreads the work for each module over the week so that I have a balanced plan where I do not work only on one module the entire day. Perhaps it would also be possible to mark the different modules in different colours. An option for postponing a task that I am not able to do at the time scheduled because something else came up would also be good.
