I forgot that the birthday year doesn't matter, just the current year +- 1 matters. I was thinking more generally when you asked about (localtime)[7], not how it applied here. While the way your calculate leap years is wrong in a general sense, it is a correct simplification for the expect inputs. A comment about this wouldn't hurt. ++.
I'd like to see an example of off by a day with certain combinations of current time, current date and current timezones.

Sure, tell me on which date the time spring forwards or falls back this year Note that I only *think* your program will return an incorrect answer for some time periods due to DST, as I have said earlier. I'm not sure what the circumstances are that causes the problem, which is why I use timegm+gmtime to completely avoid the issue.
