As well in the cold winter evenings think about the warmth of the sun and rest on a suburban site.Meanwhile, the time can be used for another - to make the right for every summer resident device that frees you from the need to seek the clock will show the exact time, but at the same time will be an interesting entertainment for children.

Sundial show local solar time, which may be different from the average lap displayed on a mechanical watch.


Sundial consist of two elements: Kadran - flat surface coated with a hourly divisions (dial) and the gnomon - straight rod fixed to kadrane.

Sundial can be made of any material resistant to weather factors: cement, stone, wood and driftwood, iron, plastic and dumping gravel, or as Nathalie 1409 - brought out from the sea of ​​pebbles and shells.To make better use of the dial light material (stone, limestone, white marble) - on it the shadow of the gnomon will be noticeable.For gnomon suit knitting needles, metal or plastic pins, long nails.

length gnomon should be slightly greater than the circumference Kadran.

Sundial become interesting and "alive" elements of landscape design, if the division of the dial to use plants and flowers, which have internal time.These include: water lily, marigold, morning glory, dandelion, daylily, thistles and other garden (60 species).For example, marigold blossoms are disclosed in 6-7 hours in the morning and closed about four hours in the evening, even in cloudy weather.


Sundial divided into three basic types: vertical, inclined (equatorial) and horizontal.

vertical sundials are usually placed on the walls of what some structures on the walls, pillars and so on.. In these hours Kadran should be directed strictly to the south, the south line perpendicular or at an acute angle to it.Gnomon is fixed slightly above the center of the dial.He has to be tilted from the vertical by an angle of 90 degrees minus latitude areas.

equatorial sundials have one drawback: they show the current time only in a certain period of the year.For example, for the regions located in the Northern Hemisphere, such clocks will run from 22 March to 22 September.However, considering that the holiday season is from spring to autumn, it should be enough.

Horizontal clock is year-round, but their testimony in late autumn and winter is not quite accurate.In these hours the gnomon is set at an angle equal to the latitude areas.Horizontal Clock is usually placed in the midst of flower beds, lawns, gardens or on the rocky island in the middle of decorative ponds.As the digital divide can be used stumps or boulders.


device sundial begins with site selection.Suitable outdoor area of ​​4 sq.m.In the next step attach the gnomon (the shadow of his will "hour hand"), applied to the face of the clock, half-hour and quarter-division (they can be cut in the plane of the material, prodolbit, paint or mark colored glass, stainless steel wire, etc.).

Time division should be made larger and more noticeable the rest.The countdown starts from the meridian line (north-south), which is best defined not by compass, and finding the shortest shadow.Put a sheet of plywood horizontally, perpendicular to it to slide up the probe tip.Every 15 minutes (for about three hours), mark the position of the shadow line connecting all the points.The shortest shadow and will meridian line.
