Description

I am able to add students that are past the current date

Steps to reproduce

1. Launch the application for the first time to load initial data.
2. Run the add command with a previous date

   Expected behaviour

   There should be an error message to prevent me from doing that

   Actual behaviour

   there is no error message

   Reason for severity

   doesnt really affect users, done usually by accident

Team's Response

Thank you for your inputs. The app still allows inputs of past date as this would still be useful for tutors to keep track or remember past sessions for the purpose of understanding how many sessions they have completed through the month, or keeping track of the number of sessions a student has completed, for the case where they had not input the date in the app but had taught the sessions physically.
