sun dial

How do you correct for daylight savings time, now?

check how many degrees north you are. Thats how the axis has to point. If you can find the North star(polaris) make it point at that. Adjust this advice, if you are on the south halve of the globe.

I had to send mine back to the manufacturer to be re-calibrated based on the GPS co-ordinates of the new location.

I heard a rumor that new models have built-in GPS correction capability, so you could carry it around instead of a wristwatch. ;-)

There is usually a small knob on the side. Unless you have a sundial that used the National Observatory time.

Turn the knob, or the dial.

From March to Nov(in states that observe Daylight SLAVING Time) Noon will b= e around 1pm DST. Set dial so shadow falls on 12 at that time and you'll be= in the ballpark. If you live East of your prime meridian(Eastern =3D 75de= g west, Central =3D 90 west, Mountain =3D 105, etc) set "noon" early - by a= bout 15 min(11:45am Standard or 12:45pm DST). If you live in the Western ha= lf of the zone, set noon late - about 15 min(12:15pm Standard or 1:15 DST).

Google "local noon calendar" if you want to be really precise; there are so= me good ones on line.

Here's a good place to start...

I thought sun dials quit working in the year 2000 due to that Y2K business.....

Had to do an update in 1999. In my case, the sundial is mounted on my deck. It was tough rotating the deck to make the adjustments.

A sun dial provides local time, without regard to artificial time zones. It is Noon local time when the Sun is directly overhead.

You elevate the pointer (gnomen?) so it is parallel with the axis of the Earth. Pointing the pointer towards Polaris will do that.

If it is accurate before the move, and you do not move further North or South, then it will be accurate at the new location. All you have to do is make it point North or South, depending on your hemisphere.

Didn't someone once make a small sundial mounted on a wrist band?

Featured on the Flintstones show, Fred. I thought Wilma would have reminded you by now.
