DAX first day of current month

I want to do Month to date and year to date calculation without using MTD and YTD functions. I know Today() stands for Today's date. In the same lines can someone please tell me how do I get the first day of current month (example 1/1/2017 currently) and first day of current year? TIA.

first day of current month = DATE(YEAR(today()), month(today()), 1)

Cool my dear friend ,


try this one.




It will give u the first date from the date.


If u choose month it will give u the start of month, if u select year it will give start of year.


let me know if any help.

This is a way to easily calculate MTD and YTD without the need to calculate the first days first:

[SalesYTD] := 
    FILTER (
        ALL ( 'Date' ), 
        'Date'[Year] = MAX ( 'Date'[Year] )
            && 'Date'[Date] <= MAX ( 'Date'[Date] )

How can I get the first day of month If I have "Year" as a parameter?

If year 2018 - I need May 1,2018

if Year 2017 - I need May 1, 2017 etc
