I celebrate it as a turning of the solar tides.

Its a personal thing for me – I know when it happens even if for some reason I am not aware of when it is supposed to be [like getting the date wrong for example] I also celebrate the equinoxes and the winter solstice.

There are no words which express correctly how it affects me – its is a feeling of rightness to celebrate it and an enormous sense of peace too is about as close as I get to it.
