Is your feature request related to a problem? Please describe.
The calendar screen does not provide with a good user expereince

Describe the solution you'd like
A new calendar view to match the User interface of talawa admin

Additional context
we can make something like this with colors and themes similar to what used in talawa

Note: Do fix the placement of add event button and remove the small calendar
