how to calculate the difference in year variables

[preeti2890]

I have a dataset which has manufacturing year  of flights as one of the variables and I want to calculate the year of use of those flights by calculating the difference between the manufacturing year and year 2015. How should I do that? Is there a function for the same?

If only the year is known (not a day within the year), then just subtract the years:
Age = ManufactYear - 2015;

Hello ,

You can calculate year difference by using below program....

data _null_;
M_year='08oct2012'D;
y_year=intck('YEAR',M_YEAR,'09OCT2015'D);
put y_year;
run;
