Matthew, I think you asked more or less the same question a few months ago: http://www.stata.com/statalist/archive/2013-10/msg00662.html At any rate, the answers given at that time should help answer this question. Regards, Joe Canner Johns Hopkins University School of Medicine -----Original Message----- From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of DeMichele, Matthew Sent: Monday, March 10, 2014 3:39 PM To: statalist@hsphsun2.harvard.edu Subject: st: date calculation I have two date variables arranged as YYYYMM and YYYYYMMDD. The first variable is date of birth and the second is date of admission to treatment. I am trying to calculate age_at_admission, but am running into trouble. Is this a possible calculation since Stata calculates dates as days since 1,1,1960? Thank you for your help.
