First, find your azimuth. Next, the Altitude (or elevation) is the angle between the Earth's surface (horizon) and the sun, or object in the sky. Altitudes range from -90Â° (straight down below the horizon, or the nadir) to +90Â° (straight up above the horizon or the Zenith) and 0Â° straight at the horizon.
Four years is one term. US presidents can only serve two for four year terms, for a total of eight years. The controlling law is the 22nd Amendment to the US Constitution.
Constitutionally, a President can only serve two elected terms. If he became President by virtue of the death or resignation of the previous prez, if the replacement term is 2 years or less, he can still run two more times. So under the current constitution, 10 years is the absolute theoretical maximum.
