With the Calendar and Timetables Application you can generate the timetable and educational calendar in a custom way.
On the one hand you can consult the general timerable of your studies depending on the course and the group you are assigned to.
On the other hand the applicative also allows you to generate a custom calendar only with the assignments you have chosen to enroll. This option allows you to generate a calendar based only on the selected subjects regardless of the course you are enrolled in. You only need to write the code for each subject in order to generate your calendar in size.
