Calendar View Scenario

I would like to ask how will I able to count and display the number of employees or users in a day (date selected) from the calendar view display (ie. employees will have to select WFH or WFO only for each date and it should be at least 50% for both options based on the number of employees)
Note: It is like tracking all employees for the day that selected the two options
Thank you and God Bless!
