I have day number in my date table and used below dax to create a new column 

fortnight = IF( Date[DayNo] <= 15, "Fortnight-1", "Fornight-2")

The above dax works to seperate the fornights. However, I am not able to get the above output like Jan 1-15, Jan 16-31 etc

Can anyone advise how to do this? I created date table using M query

[kunal15sep]

Using "Month" as a sepearate column FORMAT([Date],"mmm")

[kunal15sep · Accepted solution]

fortnight =

var lastdayinMonth= ENDOFMONTH('Date'[Date])

return

if(DAY([Date])<=15, 'Date'[Month] & " 1-15",'Date'[Month]& " 16-" & day(lastdayinMonth))
