Yes, it is STILL Christmastide! The Season of Christmas lasts until Candlemas - which is February 2nd. This is the Feast of the Presentation of Our Lord and is also the Feast of the Purification of the Blessed Virgin Mary (not that she needed purification - but she needed to fulfill the law). It is 40 days after the birth of our Lord.
So. let me get it in at least one more time this season:
Something else is observed on this day... it has to do with a groundhog named Punxsutawney Phil. The Pennsylvania Dutch legend has it - if Phil sees his shadow there will be 6 more weeks of Winter; if he does not see his shadow - it will be an early Spring (weather-wise).
