We celebrate Rosh Hashanah both in the traditional way (going to services) and by making a birthday cake. It usually looks about 50 times worse than the one above, but still cute.
Rosh Hashanah is the new year in the sense of the anniversary of the world's creation. In my steadfastly secular way, I think of it just as a day to be glad the world exists, though I enjoy all the distinctly Jewish trimmings--the music, the apples, the honey, the familiar rituals.
The holiday (like all religious things, as far as I'm concerned) is like a sturdy piece of cloth that we can make meaning out of as we please. The nice thing about it is that the cloth has been around for a long time, so it's covered with embroidery. We can add to it, while also noticing what's already there. Plus, there's the pleasing sense of continuity over thousands of years. May all who want burlap find their own.
This is a day when the sermon often concerns environmental issues. I'm looking forward to it. Here's to the world's existence and health!
