“…as it means the Cailleach is asleep and winter is almost over”, says Wikipedia
Was yesterday a day of foul weather? It depends on your perspective, I think.
From the inside of our warm kitchen, it just looked beautiful:

But if you were trying to get home on the blocked up bypass last night, it probably looked fairly foul:

That’s the chain of lights in the centre, there.
I don’t think it was a great day for “gathering firewood for the rest of the winter” either, as is also mentioned on that page. We did ours on the day before – the boys went out and cut some of the old shed wood for the stove, which burned nicely for our Candlemas feast fire, and we had candles of course:

… and candlecake…

But I keep telling myself that it’s not just a day. Imbolc is a whole period of time: the six weeks or so running up to Easter, just as Christmas or Yule relates to the weeks between then and now. It’s not so long ago that people left their evergreen Yule decorations up in the house until Candlemas eve. Perhaps a house is meant to be decorated for each festival, until the next one. We might think about doing something like that.
So, what is it a time of? Keeping warm, obviously. Making sure there’s enough fuel and candles until the winter’s end, and perhaps using up any excess supplies. Sorting out the seeds and planning the planting, as I’ve been doing this week. Preparing the ground for the new seeds, tidying up, gearing up for a busy spring.
It’s also the time of the natural hungry gap, when the last of the old brussel sprouts is eaten, and the dried pulses and the contents of the root cellars are emptied – the time called Lent, by Christians. “This word initially simply meant spring and derives from the Germanic root for long because in the spring the days visibly lengthen.” Oh yes – that’s the other thing this is the time for, isn’t it? Watching the days growing longer.
