Hi Robert & All, There is a lot of factual info on your site (and the rest of the web) about DST. What is puzzling me is the following. From 1977 on we (in the Netherlands) had DST from the last weekend in March to the last weekend in September. Loosely speaking: while solar declination was positive. In 1996, the European Union adopted the British rule, moving the end of DST to the last weekend of October. Without moving the start of DST to the last weekend of February. Why this assymmetry? Apparently another factor than day length got into play. A political gesture to keep GB in the EU? Or just the average temperature? Even then, WHY?
