- My parents were married on Groundhog Day (February 2nd).
- My husband and I became engaged on Groundhog Day.
- A good friend (I'll leave it up to that person to choose whether or not to identify him or herself) also celebrates their anniversary on Groundhog Day.
Tomorrow morning, while Punxsutawney Phil is being yanked mercilessly out of his cozy burrow to satisfy the folkloric superstitions of a bunch of fool humans, several of that sorry bunch (fool humans) will be gearing up for a day of romantic remembrance. Perhaps we were inspired by the humble, cuddly (poetic license exercised here) groundhog. Or maybe we just couldn't wait 12 more sunrises for the day of hearts and roses to arrive. Personally, I think it's just because the whole month of February is for lovers, and we should kick it off as early as possible. OK,OK -- full disclosure on my true personal story here; our first opportunity for a romantic dinner out after the purchase of the ring happened to fall on Groundhog Day.
Just for the record, February 2nd is also the holiday of Candlemas, something I know because of enigmatic references to the day in British literature and romance novels. According to the Answers.com article I've referenced, Groundhog Day has it's origins in Candlemas:
"In the British Isles, good weather at Candlemas is taken to indicate severe winter weather later. It is also the date that bears emerge from winter hibernation to inspect the weather as well as wolves, who if they choose to return to their lairs on this day is interpreted as meaning severe weather will continue for another forty days at least. In the United States and Canada, Candlemas evolved into Groundhog Day celebrated on the same date.The earliest American reference to Groundhog Day can be found at the Pennsylvania Dutch Folklore Center at Franklin and Marshall College:
February 4, 1841 - from Morgantown, Berks County (Pennsylvania) storekeeper James Morris' diary..."Last Tuesday, the 2nd, was Candlemas day, the day on which, according to the Germans, the Groundhog peeps out of his winter quarters and if he sees his shadow he pops back for another six weeks nap, but if the day be cloudy he remains out, as the weather is to be moderate." 
So Happy Groundhog Day, Happy Candlemas, and Happy Anniversary to all!
