Sundial

A sundial is a simple, yet accurate, instrument, which tell time by the movement of the shadow a pointer casts upon a dial, which marks the hours of the day. The shadow moves as the sun changes position in the sky throughout the day, and the dial tracks this movement.

For a sundial to be accurate, the pointer must be slanted at an angle equal to the latitude of its location.

Arizona is the proud owner of the World's largest sundial located in Carefree, Arizona .
It stretches 62 feet.

Thanks for this post - we have a sun dial which I had forgotten about - have to take a look now.

Trust all is well.

Wow that is one big sun dial. You never have to buy them a battery, you do not have to wind them, nor do you have to plug them in. Great way to tell time. Peace

Funny that you should post this....my family, and I, were in Nashville this weekend admiring a sundial. We were thinking we should put one in our garden. And now your post....what a sign!
