Agreed - in my mind the easiest way to consider it is to consider the 29th as an infinitesimally short day on non-leap years. On the 1st of March that day has passed and they are 18, on the 28th of Feb that day hasn't started.
The same tactic works for working out when one month from the 31st August is
I also can't see it any other way. Also the birthday of a person doesnt even need to be near the potentially missing date for the same 'conundrum', two people a couple of years apart but otherwise the same birthday who comit a crime on the same day in july (but in different years), the day before they becomes 18, will also each have lived a different number of days. I think they should both be treated as not yet 18, even though they don't have the same age in days.
