Date is Numerical or Categorical

[Kishan Jadav]

I think we can perform addition/subtraction on date.

Let's take example of android version release date: Oreo released on 21th aug,2017 and Pie on 6th aug,2018. So by using subtraction we can say that Pie is release after 15 Days,11 Months and 0 year after Oreo released. 

So I think  date is of numerical type.

I am still in confusion whether Date is Numerical or Categorical ?

Hi Kishan, let me try to assist

Operations like add/sub/mul/div has nothing to do with data being Categorical or Numerical. If the data is represented in numbers, these operations can be done. Had the data been represented as text then such operations wont happen.

This classification of data (Categorical or Numerical) is basis the nature of the that dataset. 

Here, date is categorical because it's components (dd-mm-yy) belong to group of values. Date will always be from 1 to 31,  month will be from 1 to 12 or Jan to Dec and so on. On the other hand as an eg Jersey no does not belong to a group of values. Its numerical, as it can have any values (eg 99, 10, 07, 51 etc)

Hope this helps to resolve the confusion.

Thanks
