    Purpose of use
    I used this website to calculate sunrise and sunset times of a suburb of London, UK to find out the effects of altitude setting.
    Comment/Request
    I found many sunrise sunset time websites havefigure mismatches. Luckily I found this website, and I found that since the place I am calculating has an altitude of more than 100m, the sunrise and sunset times can have as high as 2 to 3 minutes' difference from 0m altitude.
