I have a study that has a starting point of 1998. I also have the variable "event date" which consists of a number either +/- the starting point. I would like to convert this number into "year of event" to determine in what year after 1998 the event occurred. Is there a way to easily code this?

Whist the above two answers are completely correct, I am questioning what the question is. You state you have a starting point of 1998, which is fine. It is this event date variable which I am not sure on. Does this reference a time interval from the year or something else. I.e. does it contain days since 1998, years since then, quarters, or is it something completely adhoc such as category 2 indicates 5 years.
