From the Canadian Encyclopedia:
The origins of Groundhog Day lie in medieval Europe, where the day was known as Candlemas Day, a Christian festival named for the custom of lighting candles on that day. There were sayings that carried the observations of the time of year in general.
In Scotland, conventional wisdom said,
“If Candlemas Day is bright and clear,
There’ll be twa [two] winters in the year.”
In England, the saying was somewhat more elaborate:
“If Candlemas be fair and bright,
Come, Winter, have another flight.
If Candlemas brings clouds and rain,
Go Winter, and come not again.”
But maybe there’s more to Groundhog Day than meets the eye… National Geographic has an interesting article: Groundhogs Aren’t Looking for Their Shadow—They’re Scoping Out the Opposite Sex
Here are some of the predictions for 2015:
Also called: Purification of the Blessed Virgin (Greek Hypapante), Feast of the Presentation of Christ in the Temple. Observed 2 February in the Latin Rite.
According to the Mosaic law a mother who had given birth to a man-child was considered unclean for seven days; moreover she was to remain three and thirty days “in the blood of her purification”.
Forty days after the birth of Christ Mary complied with this precept of the law, she redeemed her first-born from the temple (Numbers 18:15), and was purified by the prayer of Simeon the just, in the presence of Anna the prophetess(Luke 2:22 sqq.). No doubt this event, the first solemn introduction of Christ into the house of God, was in the earliest times celebrated in the Church of Jerusalem. We find it attested for the first half of the fourth century by the pilgrim of Bordeaux, Egeria or Silvia.
From the International Business Times:
You would be forgiven for forgetting to put Imbolc, or Saint Brigid’s Day, into your diary. But the Gaelic festival – observed annually on 1 February – is one of the oldest celebrations marking the beginning of spring, and has a rich history in Ireland, Scotland and the Isle of Man.
