https://communities.sas.com/t5/SAS-Programming/how-to-calculate-the-difference-in-year-variables/m-p/502543#M134161 <P>I have a dataset which has manufacturing year&nbsp; 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?</P> Mon, 08 Oct 2018 22:26:27 GMT preeti2890 2018-10-08T22:26:27Z https://communities.sas.com/t5/SAS-Programming/how-to-calculate-the-difference-in-year-variables/m-p/502543#M134161 <P>I have a dataset which has manufacturing year&nbsp; 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.
