Start date: Specify the start date of the forecast. Elevation: Specify the elevation of the observation site in meters. Time zone: Specify the local time of the city you wish to display. Example: Japan has one time zone, so display Tokyo. Understanding the forecast results *The azimuth assumes north is 0°, east is 90°, south is 180°, and west is 270°. *It assumes a flat horizon without taking into account the native terrain. *The forecast results have several seconds of calculation error, which increases at high latitudes. *Time of sunrise and sunset - calculated as the time when the upper edge of the sun meets the horizon. *Time of start of dawn and end of evening - calculated by brightness before sunrise and after sunset (the limit of brightness when a star of the first magnitude emerges) and when the sun's center height is 6° below the horizon. *The vertical latitude indicates the negative value of the west longitude and southern latitude.
