Document Summary
Antipodal location-the point diametrically opposite to the other side of the earth. Longitude: 180 32 = 148 e (180 - #), flip direction from e to w or w to e. Take the difference between longitudes and divide 15 to get time difference in hours between time zones. Take time in current time zone, add or subtract difference to get new time.

North: spring equinox (march) to autumn equinox (september) South: autumn equinox (september) to spring equinox (march) North: autumn equinox (september) to spring equinox (march) South: spring equinox (march) to autumn equinox (september) Declination = 23. 5 x sin [(360 / 365) x (284 + n)] During winter solstice, north declination = +23. 5, south declination = -23. 5. During summer solstice, north declination = -23. 5, south declination = +23. 5.
