As the nights get longer and the days get shorter in the Northern Hemisphere, it is useful to know when the sun rises and sets. A useful UK reference is http://astro.ukho.gov.uk/nao/miscellanea/UK_SRSS/.
It amazes me that we are half way already to the shortest day! I don't want to wish my life away, but I always welcome the time when the days start to lengthen again. Even more, I welcome the return of migrant birds from Africa in April such as Swallows, House Martins and Swifts.
