thank you for your response , but is there another way to make it dinamically , means that it take the date automatically exemple if we were in 201 , i habe to change (2018,1,1) b myself to (2019,1,1) and i want it to be dynamic ( not static)

Hello,

there are two ways I can tell you by now.

Adapting @Greg_Deckler you can make the year dynamic.

Measure = DATEDIFF(DATE(YEAR(TODAY(),1,1),TODAY(),DAY)

If you have a DateTable, which is many cases highly recommended you could use

Measure = COUNTROWS(DATESYTD(DateTable))

Hi .. wondering if you can advise .. I keep getting an error when using this function:

Measure = DATEDIFF(DATE(YEAR(TODAY(),1,1),TODAY(),DAY)

Too many arguments were passed to the YEAR function. The maximum argument count for the function is one.

Hi,

Try this

Measure = DATEDIFF(DATE(YEAR(TODAY()),1,1),TODAY(),DAY)

@asmagh,

Create new a new table using DAX below.

Date = CALENDAR("2018/1/1","2019/12/31")

Create measure using DAX below.

Measure = IF(MAX('Date'[Date])<=TODAY(),DATEDIFF(MAX('Date'[Date]),TODAY(),DAY),DATEDIFF(TODAY(),MAX('Date'[Date]),DAY))

Use slicer to filter your measure.
