Since I’m cycling to work these days I’m very conscious of when its light and dark outside. (I’ve got lights obviously though).
So I found a few websites that did sunset/sunrise times for a specific date/location. Made me wonder how it all worked so I managed to find an Excel Spreadsheet/Visual Basic version to get at the raw calculations (I’m not an astronomer!)
The latest Work in Progress result can be found here.
Very limitted at the moment but might make it a bit more interactive.
