February 2.

Halfway between the winter solstice and the spring equinox.

Celebrated for thousands of years by most advanced religious
traditions.

Has been westernized as St. Brigid's Day: St Brigid was supposedly the
daughter or employee of the inkeeper in Bethlehem.
When Mary and Joseph arrived, the hotel was full and the well had gone
dry. The innkeeper left Brigid in charge, with strict instructions not
to sell any portion of the meager food and water reserves to anybody.
According to legend, Brigid obeyed the innkeeper and did not sell them
any food or drink-- but she gave freely of her own personal loaf of
bread and flask of drinking water. The legend says that after the holy
family left to go to the stable, Brigid noticed that her loaf of bread,
which had been almost entirely consumed by Mary and Joseph was fully
restored, and her water flask was brimming with cool, clear water.
Charming tale.

Also previously known as Candlemass, marking the end of Mary's ritual
purification period following the birth of Jesus.

Also previously known as a heck of an excuse to party, while
recognizing any number of polytheistic dieties. :-)

Now popularly known as "Groundhog Day." Any of the old stories are more
interesting than some tradition about a burrowing animal and a shadow.

Ought to be a boating holiday. It's halfway between solstice and
equinox, boating weather and longer daylight hours are returning to the
northern latitudes.
