Cannot create Mesure for date column

[Bass_Thab]

Hi,

I am a newbie. I tried to create a formula to get moth from the date column. However, I could not put the header name in the formula. It seems invisible. 

Do you have any suggestions?

@Bass_Thab 

you can try to create a column 

or you can try something like below in a measure

month(max(date))

month(min(date))
