What's the fun of travel without weird cultural differences?

I have nothing to say about this, but i think its pretty cool.

In korea I am a year older, because everyone is born 1 year old.* This is, supposedly, because they count the gestational period in the womb as a year. Alone, this is just sort of unusual, BUT...

while they do celebrate their actual birthday's, they don't consider themselves to be a year older on that date. Everyone turns a year older on the same day - the lunar new year. Therefore, conceivably, if you were born the day before the lunar new year, you would be a 2 year old the second day you were alive.

Moira says - and i think this makes a lot of sense - that because Korea is a super Confucian country, and age is so important here, this makes things a lot simpler. If you were older than someone half the year, but the same age the other half, then your cultural relationship to them would be in constant flux. Big brother would become friend, and then go back to being big brother, and thats just confusing.
In this system, your relationships are set.
As usual though, wikipedia does a better job explaining it than i do:

*It's 3 in the morning, but still, i should know this= Is it "1 year old" or "1 years old"? Dammit.
