How to get the calendar week from current date

Hi All,

How can I get the Calendar Week from the Current Date in a Calculated Column of a Calculation view.

I know that if we pass current date to M_TIME_DIMENSION table we can get the result in CALWEEK field and can join it to my view.

But in my model I don't want to use the M_TIME_DIMENSION table. I want to get the Calendar week calculated in a Calculated Column of my Calculation view.

Thanks
