Mine is Songkran Festival. This is a New Year festival in Thailand during 11-13 Apr. It's known as Splashing water festival internationally. We pour water onto hand of elderly people while they bless us good wishes. Later on we play splashing water to each other everywhere across Thailand.
Amen to that - Jazz is a really intelligent music and I always find great people on such concerts/festivals. And it seems that the Holi festival has far outgrown the borders of India - we will have it for the 2nd or 3rd year in Bulgaria very soon. It seems like a great concept and lots of colorful fun. Myself I am a big sucker of music, so when I hear a festival I always think of music - Exit in Serbia, Sziget in Hungary, our very own Spirit of Burgas are a few I've already been on. Glastonbury, Rock am Ring and Burning Man are some that I am yet to have the pleasure of visiting
As a Inidan and Gujarati, I like NAVRATRI festival which is best for me. I enjoy Dandia and Garba for nine days.
