For angle with d integer degrees m minutes and s seconds: d° m' s" The decimal degrees dd is equal to: dd = d + m/60 + s/3600. 1 Degree (of arc): 1 degree of arc is define as 1/360 of a revolution. To create your own sundial use the hour line angle calculator at the top. Step 1: Input time in number format. Calculator for the angle between the two hands of a clock and the angle of hour hand and minute hand. Unit Descriptions; 1 Hour Angle: 1 Hour angle is 1 turn/24 or 15°. Uncheck Full Scale and use the running list of measurements below to mark out Hour and 15 minute increments around the circumference of the dial. Cut a gnomon at the same angle as your latitude then tape it standing on the 12 Noon line. Calculate Angle between Clock Hands. Hour angle, in astronomy, the angle between an observer’s meridian (a great circle passing over his head and through the celestial poles) and the hour circle (any other great circle passing through the poles) on which some celestial body lies. Please enter a time of day. Example. Description: This calculator has been developed primarily to extract the Greenwich Hour Angle, GHA, of a celestial body from MICA (Multiyear Interactive Computer Almanac) in a convenient way, but it can be used in combination with other almanac software or printed almanacs as well. Cut and fix the Gnomon (the triangular piece) to the sundial face, with base along 12 o'clock line, and latitude angle end at centre. In the diagram below, LHA is the angle BNU on the Earth’s surface which corresponds to the angle ZPX in the Celestial sphere. Unlike the Nautical Almanac and ICE (Interactive Computer Ephemeris), MICA only provides the … In other words, it is the angle between the meridian of the… This angle form has each degree is divided into 60 minutes and each minute divided into 60 seconds.
