    • n sundial An instrument for indicating the time of day by means of the position of a shadow on a dial or diagram. The shadow used is generally the edge of a gnomon, which edge must be parallel to the earth's axis, about which the sun revolves uniformly in consequence of the earth's diurnal rotation. If a series of imaginary planes through the edge (one in the meridian and the others inclined to one another by successive multiples of 15°) be cut by the plane of the dial, the intersecting lines will be in the positions of the hour-lines of the dial. The shadow of any given point upon the gnomonedge will fall at different positions on the hour-line according to the declination of the sun, and this circumstance may be used to make the dial show mean instead of apparent time. But this is inconvenient, and seldom used. Portable sun-dials used often to be made so that their indications depended exclusively on the altitude of the sun; such dials require adjustment for the time of the year. See dial.
