PURPOSE: An application method for sunrise and sunset time according to positions is provided to improve usage convenience using only reference point, longitude comparison point, and latitude point. CONSTITUTION: A longitude and a latitude are inputted of a target point moved in the specific area through a GPS(S1). A time compensated value of sunrise and sunset time of the target point is outputted from the difference of the longitude and latitude according to the coordinate of the inputted target point and the set reference point(S2). The outputted time compensated value is copa time compensated value hardness size and latitude size of the target point and the sunrise and sunset time of the reference point are added or subtracted(S3). |
