Thnaks in advance

Duration =
VAR CurrentDate = CALCULATE ( MAX(Table[effective from] )


var LastDate = CALCULATE(
MAX(Table[effective from]),
Table[effective from] < CurrentDate )


VAR DD = DATEDIFF ( LastDate,CurrentDate, Year )

Hi @HassanAli123 ,

You can use DATEDIFF function here. 

Eg - Result_for_years = DATEDIFF(effective_form, Today(), Year) 
(for first row, this will return no. of years between 01/01/2012 to today's date)
Result_for_months = DATEDIFF(effective_form, Today(), Month)
(for first row, this will return no. of months between 01/01/2012 to today's date)
Result_for_days = DATEDIFF(effective_form, Today(), Day)
(for first row, this will return no. of days between 01/01/2012 to today's date)

@HassanAli123 -> Please mark this as a solution if it helps you. Thank you.



actually you did not get my point. the person is same in both designation. i want to calculate duration separately for assistant manager it should calculate till 2014 mean 2 years and 8 year 2 months for head roll
