Sundials and Scratch Dials
Sunny Hours


Sundials tell the local apparent time, time by the sun.

Here in The Lakes we are about 3 degrees west of London, so the time is 12 minutes late; and an hour more late in Summer Time. And there is a further small correction due to the Equation of Time; if you want to know about these things then read a book, try Waugh 1973. It is possible to make very accurate sundials, the Gibb's heliochronometer is one such.
