I am working on a module which is a an appointment module in a calendar format. Now there is a problem that I tried to solve but failed in doing so. The problem regarding the module is:-
- Making the calendar appointment recent. ( for example, if todays date is 11/2/2021 then any appointment that is done today and set on any date before 11/2/2021 should be cancelled)
I will be adding the whole code for my module reference
Small notice: I am still a beginner in programming so pls take me easy because I am still learning and this module is a practice given by my institution.
thank you
Code ( actually its three files)
