We only ever work with the current year (plus or minus one).
Which by definition includes the Feb/Mar boundry, so leap year can affect it by a day...
I don't recall what the rules are regarding the 'leap year skip',
See the google link above (searched for 'leap year calculation'); Also another reason to use Date::Calc, Date::Time, etc modules.
but I'm pretty sure it won't affect this code for a very long time.
Yeah.. i'm pretty sure that's what people said about the year 2000, which came and went, as will 2038 .. as will 2100 (which has only 28 days in Feb) .. Sure, that's a little way off, but on prinicpal you should care about the accuracy of your code, also, what about this realistic (at least plausible) scenario: Someone sees your snippet here and adapts it to their code, which isn't limited to the current year (e.g. days to/from a certain future date) and 2100 might be a valid input ..
