Happened today, I think.  Technically it is a moment, when the sun appears to ‘stand still’, but we usually take the whole day, and think of it as the longest night (not the darkest; depends on whether the moon is shining, or it’s cloudy). Not the beginning of winter, which some people probably have had since November, nor yet the middle, but definitely one for the thick duvet, warm fire and artificial lighting.  We are having some comfort food: beef stew and rice pudding.
