Dax issue

Anonymous , It has two-part, one that 1st month, 2nd-month formula

I discussed a similar thing based on the first date of sales in this video - refer - https://www.youtube.com/watch?v=Q1vPWmfI25o

 

Taken the Min date as column and taken diff in month post that.

Here this can be as a new column

new column = datediff([reg date],[sale date],Month) +1 & " Month "

Second is the display which is hybrid

 

Hybrid display with Matrix Column and measure
