Duration calculation is common in many SAS programming tasks. Whenever an event occurs between a start date and an end date, one may need to compute the elapsed duration (in seconds, minutes, days) for the said event. The programming challenge in SAS often arises from having to perform operations across many observations for the same person. As most books and papers about SAS have not fully explored the LAG function in the context of duration calculation, the author now wishes to leverage the LAG function and offer a different programming approach.
