Today, along with New Year, is an important holiday in Korea called chuseok (추석). I wrote about this holiday extensively last year, but I wanted to wish Koreans everywhere a happy Thanksgiving this year too. :)
I found this site which has some very nice pictures about Chuseok, and even though I can’t really read it, I hope you might enjoy.
Also, many KPop groups have special Chuseok messages for fans and such. I found this one recently by the boy-group TVXQ (they’ll be featured on a KPop Saturday coming soon):
P.S. The Korean tourism industry has a nice list of Korean holidays for reference, including Buddhist ones, for 2012.
P.P.S. The good folks at TTMIK have a nice write-up on Chuseok too.
