Need help converting date functions from SQL Server to DAX

[transcend]

Hello, I am trying to convert the following date function from t-sql to dax:

select
EOMONTH(DATEADD (dd, -1, DATEADD(qq, DATEDIFF(qq, 0, myDateCol) +1, 0)), 1)
;

So far I have DATEDIFF as  

DATEDIFF( 0, myDateCol, QUARTER) 

however I can't figure out how to do DATEADD. For that I have this:

DATEADD(0, DATEDIFF( 0, myDateCol, QUARTER)+1, quarter)  

 I got this function from https://dax.guide/dateadd/

I know EOMONTH exists in DAX as show here: https://docs.microsoft.com/en-us/dax/endofmonth-function-dax

I was hoping someone can provide my a hint or help me. Thank you.

@transcend , Assuming you can add three month in place of quarter

Datediff will give number, so not sure how you are using that

Datediff([Date1], [Date2], Day) //in place of date you can use month, quarter, year etc

In place of dateadd, you have to use date

say 3 month in place of quarter

date(Year([MyDate]),Month([MyDate])-1, Day([MyDate]))

Subtract or add days simply

[MyDate] + [Days]

[MyDate]+5

For end of the month

eomonth([MyDate], 0) //current month end date
