Imbolc
Imbolc is a Pagan holiday celebrated from February 1 through sundown February 2. Based on a Celtic tradition, Imbolc was meant to mark the halfway point between the winter solstice and the spring equinox in Neolithic Ireland and Scotland. The holiday is celebrated by Wiccans and other practitioners of neopagan or pagan-influenced religions. Imbolc is just one of several pre-Christian holidays highlighting some aspect of winter and sunlight, and heralding the change of seasons.
