There's a lot of old European lore associated with February 2, some of which has made it to America. We think of it as the midpoint of winter, when thoughts turn toward spring, but apparently in some places of old it was considered the start of spring. That's hard to imagine here, since January and February are deep-dyed winter months, with typically nothing springlike going on. I recall a year when a mild spell at February's end lasted long enough that it seemed spring had come early, which was cause for much remark. That I remember it so well shows how unusual it was. Let's hope it remains unusual (despite its loveliness), because however much one dislikes winter, February is supposed to be cold, at least around here.
My birthday and the Super Bowl both fall close to Groundhog Day, though I had never really given it much thought before. I don't know if there is any significance to being born on or near a cross-quarter day, but having learned that in some blessed places February 2 signaled the start of spring, I now have a new way of thinking about my birthday. Just the bare hint of an association with spring so close to my date of birth is radical enough that I'm going to adopt it regardless of what the weather is actually doing. If I'd known this a long time ago, it would have helped me through many freezing, sleeting, blizzarding birthday celebrations, but that's no matter--I know now.
Regarding the Super Bowl, I'm not sure whether it's a coincidence or not that it falls near the February cross-quarter. Football seems to have no connection with candles, ewes, lambs, Saint Brigid, groundhogs, motherhood or any other cross-quarter traditions you could name, but you never know, there might be a hidden link, just as there's a connection between the November cross-quarter, harvest, and Election Day. Candlemas in the late Middle Ages was apparently heavy on candlelit processions and the intoning of chant, all very pious and reverent; football (and the spectator sport of consuming heavy food and drink) seems rather more Roman in style (though February in ancient Rome actually marked a time of purification). However that may be, it does seem somehow American to mark the deepest part of winter with a head-bashing contest.
As for me, I happened to be looking through some old calendars on the evening of February 1 (Groundhog Eve, if you will) when I came across the special edition newspaper I had totally forgotten I'd saved from President Obama's first inauguration. While I don't know if the January date of our presidential inaugurations (since FDR) signifies anything other than a date conveniently close (but not too close) to New Year's, it does fall fairly near the February cross-quarter. (Let me remark parenthetically that I looked at that newspaper in some consternation--speaking of head-bashing and headaches--before throwing it away with some old calendars I found in the same cubby.)
The next day, as it happens, I found an article in which someone was discussing possible ways to celebrate Candlemas/Groundhog Day/Imbolc in modern times, and cleaning house was one suggested activity. Glad to know I was on to something, I took down my little Christmas tree (which I'd been saving for Candlemas), dusted, mopped, shook out the rugs, and took out the trash containing all the old calendars and newspaper. I often play music while cleaning, but this Groundhog Day I actually found myself singing along. Well, spring fever will do that to you.
