I got confused after seeing the code in solution that definition and solution didn't match so this is what I found on Wikipedia "(except for years evenly divisible by 100, which are not leap years unless evenly divisible by 400)" but earlier it was written here "except for years which are both divisible by 100 and not divisible by 400."
I maybe wrong here, not knowing that these two statements maybe are indicating two different things, if that's the case, then feel free to not apply the changes and do let me know. 😄
P.S. - I corrected "effects" to "affects" too.
Everybody in the Southern hemisphere experiences winter in July and that's normal, so the original remark added an unnecessary (and off-topic) layer of confusion.
