How to subtract the number of days from TODAY() until a specific date

[Anonymous]

I created a measure called _dateInc that brings me the date when the last product was lost.
I would like to know how many days the stock has been without losing new products, and with that, I would like to subtract TODAY() with the day of the last loss (_dateInc). I tried to use:

measure = TODAY () - [_dateInc]

but I received a strange date, with the year set in 1900. I just want to know the number of days.

@Anonymous , You can subtract and add Days date without any function.  If you subtract a date from date, it will return diff in term of timestamp

Use date diff if these are two dates

datediff(TODAY () , [_dateInc],DAY)

@Anonymous Please try 

measure = DATEDIFF([_dateInc],TODAY(),DAY)
