Imbolc (also known as Candlemas, Imbolg) has its origins as a Gaelic festival of light, to mark the first stirrings of spring.
The name derives from an Old Irish term which translates to in the belly.
Imbolc is also known as the Feast of Brighid, a Gaelic fertility goddess.
Imbolc has been a traditional time of weather divination, and it may be no coincidence that Imbolc and 'Groundhog Day' are so close together.
Imbolc is one of the four Greater Sabbats.
Imbolc is traditionally celebrated on January 31st.
