Need Dax Function when select a date or month or 2 months or Quarter we will get Number of days MTD, QTD and YTD according to current date.

for an example , 

if we select 1-May-2024 from dropdown or from slicer of date range and today is 25-May-2024 then it will give MTD days number is 25 days, QTD days number is 55 days, and YTD days number is near about 145,

Selected Date  =  1-May-2024

Today Date = 25-May-2024

MTD = 25  ,    QTD = 55   and   YTD = 145

Hi @proavinash ,

I recommend that you use the DATEIFF() function, which is used to calculate the difference between two dates.

We can create three measures.

MTD = 
var _date1=DATE(YEAR(TODAY()), MONTH(TODAY()), 1)
var _date2=TODAY()
RETURN DATEDIFF(_date1,_date2,DAY)+1

QTD = 
var _date1=DATE(YEAR(TODAY()), FLOOR(MONTH(TODAY())-1, 3)+1, 1)
var _date2=TODAY()
RETURN DATEDIFF(_date1,_date2,DAY)+1

YTD = 
var _date1=DATE(YEAR(TODAY()), 1, 1)
var _date2=TODAY()
RETURN DATEDIFF(_date1,_date2,DAY)+1

Then the result is as follows.

Hi @proavinash ,

You can use the DATESMTD, DATESQTD and DATEYTD functions to calculate the corresponding number of days, for example:

MTD Days = COUNTROWS(DATESMTD('Calendar'[Date]=TODAY()))
QTD Days = COUNTROWS(DATESQTD('Calendar'[Date]=TODAY()))
YTD Days = COUNTROWS(DATESYTD('Calendar'[Date]=TODAY()))

Then if you want to then control the returned result based on the number of items selected by the user, then you can slip in another IF function.

Did I answer your question? If yes, pls mark my post as a solution and appreciate your Kudos !

Thank you~

Thanks for your help, but this is not working because of i have large database in which near about 20 lacs of line item so countrows not give a proper solution, in a month either 31, 30 or 28 days, and countrows count all rows in a month or year,

@proavinash 

MTD = 
CALCULATE(
COUNTROWS('DateTable'),
'DateTable'[Date] <= TODAY(),
'DateTable'[Date] >= DATE(YEAR(TODAY()), MONTH(TODAY()), 1)
)

QTD = 
CALCULATE(
COUNTROWS('DateTable'),
'DateTable'[Date] <= TODAY(),
'DateTable'[Date] >= DATE(YEAR(TODAY()), FLOOR(MONTH(TODAY())-1, 3)+1, 1)
)

YTD = 
CALCULATE(
COUNTROWS('DateTable'),
'DateTable'[Date] <= TODAY(),
'DateTable'[Date] >= DATE(YEAR(TODAY()), 1, 1)
)

💌 If this helped, a Kudos 👍 or Solution mark would be great! 🎉
