Purpose of "Mark as date table" in Power BI

[Keerthika]

Hi,

My "orderdate" column in fact table is not contiguous, so I created  "Date" table using dax. I calculated YTD using date column in "Date" table. YTD shows correct value without even using "Mark as date table". I want to know the purpose of "Mark as date table".
Can anyone help with this?

Thanks.

Hi @mussaenda ,

Thanks for the reply. I also referred to the same link. I followed the same procedure as in the link, but I couldnt find any difference. YTD works fine even without using "Mark as date table" option. Can you explain the purpose of "Mark as date table"
Thanks.
