...Really, I do have five.
I celebrate the secular December 31/January 01 new year the most. It's the one I've grown up celebrating, and it means the most to me. Traditions will do that.
Next, I celebrate Chinese New Year. Again, a celebration I grew up with, more an excuse to throw a party and eat that delightful bean candy stuff that I haven't had in years. My father made a point to make friends with the Chinese grad students coming into
UAF, because they were strangers in a strange land and he doesn't like people to feel alone and left out, and that meant for us children, more holidays, more friends, and interesting things to eat (though I could, at the time, have done without the chili oil in the soy sauce that I ate unexpectedly. They tell me that I was rather dignified, even with tears pouring out of my little eyes).
After that, a holiday unique to myself, my former fiancee the Lady E., perhaps at one point
boojum, and of course
pyrogenic: Joshian New Year. The Lady E. and I started a cult to worship
pyrogenic, you see, and the cult had a new year based on his birthday. We were fourteen and fifteen; Pyro was sixteen. It was delightfully silly.
Finally, Samhein. I celebrate it, of course, but it's never really pinged as "New Year" to me, perhaps because I have so many. The symbolism of the snow, and the death of the old year touch me, but somehow don't equate to "New Year." I suppose that's because I think of New Year as birth, and celebration, rather than black deep hibernation? Ostara is a far more logical New Year to me.
Also showing up on my New Year radar is the New Year from the Jewish part of my heritage. It's a heritage I haven't explored as much as I might, or as much as I might like, but it's still there. I've never celebrated that new year, but I will at some point in my life.
I have five, or more, different celebrations of a new year to mark. Every day, really, is new...
