[Rosie] Well, that's nice, but I live in the United States. I find that it even gets dark fairly early in the northern states. I don't know about Canada, but I've heard that it's around 8pm or 9pm at the latest when it gets dark there.
(KS) The 49th parallel misses us by some way. The latitude of my place is 51.318 and Edinburgh and Glasgow are not far of 56°N. The clocks are an hour ahead of the Greenwich meridian in summer but not in winter. There are few things more gloomy than a cloudy December afternoon in Britain. Pretty well dark at 4 pm.
