We celebrate our own version of the wheel of the year, mostly organised around the solstices and equinoxes, but we don't call them by the pagan names. Usually we just say "merrymeet" and leave it at that (spring merrymeet). Usually we invite some of our closest friends for a meal, but we always do a little ritual or something, based on whatever seems right at the time. For example, one year for the December solstice we had a wishing wreath, where I had a plain wicker wreath, and everyone poked flowers/leaves into it while they were making their wishes for the coming year. We then lit a candle in the centre to send the wishes out there to the Universe. Must've been pretty powerful cos they all came true !
