Lighter evenings from next week!

Even though the mornings get darker for a while yet, the evenings start to get a little bit lighter here just before the winter solstice.  I think this will depend on your location.  By the end of next week the evenings here stay lighter by 1-2 minutes. By the end of January it is very noticeable. The change is slow at first but speeds up: by early March it is light until 6.30pm. I think the rate of change follows a sine wave with the fastest change around the equinoxes.

Although there is something nice about cosy evenings in, I prefer light nights.
