Start of Goose Month
The Roman festival of Larentalia was held on December 23, but was ordered to be observed twice a year by Augustus; by some supposed to be in honour of the Lares, a kind of domestic genii, or divinities, worshipped in houses, and esteemed the guardians and protectors of families, supposed to reside in chimney-corners. Others have attributed this feast in honour of Acca Larentia, the nurse of Romulus and Remus, and wife of Faustulus.
During this festival, offerings were made to the dead, usually at altars dedicated to Acca Larentia. A sacrifice was typically offered on the spot where Acca Larentia is believed to have vanished.Larentalia was part of a series of ancient Roman festivals and holidays celebrating the end of the old year and the start of the new. http://en.wikipedia.org/wiki/Larentalia
Dies Natalis Invicti Solis
Wren day also known as Wren’s Day, Day of the Wren, or Hunt the Wren Day (Irish: Lá an Dreoilín) is celebrated on 26 December, St. Stephen’s Day. The tradition consists of “hunting” a fake wren, and putting it on top of a decorated pole. Then the crowds of mummers or strawboys celebrate the wren (also pronounced as the wran) by dressing up in masks, straw suits and colourful motley clothing and, accompanied by traditional céilí music bands, parade through the towns and villages. These crowds are sometimes called wrenboys. http://en.wikipedia.org/wiki/Wren_Day
