It’s quite noticeable how quickly the sun rises and sets over here, and I was wondering whether New York lost out all year round. I knew that it wouldn’t be the case (school taught me that much) but wanted to find out more, so here are my findings. There’s a lovely spreadsheet to support all this, as you can imagine, available on request. Please stop now if you’re not a geek.
This year, New York will get 23 hours 40 minutes less sunlight than London’s 4,488 hours 7 minutes. On 27 March and 18 September, the sun rose/will rise at the same time in New York and London (05:47 and 06:40 local time respectively). Before 24 March and after 18 September, the sun rose/will rise earlier in New York than in London. On 11 March and 2 October, the sun set/will set at the same time in both cities (17.59 and 18:35 respectively). Before 11 March and after 2 October, it set/will set later in New York than in London.
The longest New York day was 23 June (15 hrs 06 mins). In London it was 19 June (16 hrs 39 mins). The shortest will both be on 21 December (9 hrs 15 mins in New York and 7hrs 49 mins in London). That’s where New York benefits, with much longer days in the winter. Something funky goes on during the summer and winter solstices where you get a couple of minimums/maximums. I think this is because of the rises and sets not peaking at the same time. If you have a pad in both cities, and want to maximise your daylight time, spend the winter in New York, fly to London for the summer on 19 March and fly back to New York on 24 September. If you like all things dark (Mark), then do the opposite.
So in essence, in the height of summer, the New York day is 1 hr 33 mins shorter than that in London. But in the depths of winter, our days will be 1 hour 27 minutes longer than those in London.
