Today is Imbolc, the Celtic cross quarter day halfway between the Winter Solstice and the Vernal Equinox. Light a candle and celebrate the days getting just a little longer. From the BBC:

Like many Celtic festivals, the Imbolc celebrations centred around the lighting of fires. Fire was perhaps more important for this festival than others as it was also the holy day of Brigid (also known as Bride, Brigit, Brid), the Goddess of fire, healing and fertility. The lighting of fires celebrated the increasing power of the Sun over the coming months. For the Christian calendar, this holiday was reformed and renamed ‘Candlemas’ when candles are lit to remember the purification of the Virgin Mary.
