Imbolc falls on the first of February, half way between the winter solstice and the spring equinox. It is a pagan festival associated with the pagan goddess Brigid also known as Saint Bride by Christians.
The town of East Kilbride in Scotland, south of Glasgow has an association with Bride as Kilbride means the Church of Bride.
Lighting candles and making crosses were traditional ways to celebrate this day.
The festival celebrated increasing daylight, snowdrops, lambing, and anything to do with spring.
On my walk today, I noticed snowdrops for the first time at the riverside downstream of Castle Falls in Calderwood.

They grow more prolifically upstream at the Torrance House end of the Rotten Calder Gorge, where large drifts of them in the woods form quite an impressive sight.
Despite it still being very chilly, I noticed, while out on my walk, little shoots appearing from under the leaf litter, woodland plants ready to burst out and flower before the leaves of the trees come out and cast them into the shade.
Check out what looks like the leaves of wild garlic.
In this situation, they are well advanced, not wasting any time, taking advantage of the heat trapped in this sheltered and, particularly, sunny spot.
It may have just turned February, but spring is definitely around the corner.
