Build+Your+Own+Henge

Now I'm going to tell you how to build your own Stonehenge.

Materials:
 * An outside space, hopefully offering a 360º horizon view. You will need to leave markings on the ground. Find a place where they can be left undisturbed.
 * A center stake for a reference point.
 * Fifty feet of rope.
 * 20 to 30 marker stones/small stakes or another means to mark your locations.
 * A compass.

Steps to building your own Stonehenge circle.

1. Anchor a reference stake at the center point of the circle and put the compass on top of it.

2. Find north and place a marker at 50 feet north of the center.

3. Repeat the process for east, west, and south. (The rope is used as a guide to insure that all markers are equal distance apart.

4. Again, using the rope as a guide, place a small marker stone every few feet around the perimeter of the circle.

5. The center of the circle now becomes the fixed reference point and the westward facing perimeter is where you will be placing the sunset markers.

6. The calendar can be started at any time, but the solstice sunsets are the most fun. The Northern Hemisphere is the reference for the following dates. The summer solstice, which happens on June 21 or 22 each year, has the longest daylight time. It is also the first day of summer. The winter solstice, on December 21 or 22, has the shortest, and officially kicks off winter. The autumn equinox occurs on September 21 or 22; the spring equinox occurs on March 20 or 21.

7. Mark the point of sunset with the stake marker.

8. Tag the marker with the date of sunset.

9. Repeat the process every seven days. Over the weeks and months note that the sun appears to "walk" faster at some times of the year than others.

10. When you have finished (you could do the you will have a working astronomical calendar.
