Why the day gets longer and shorter in Changchun
Earth's axis is tilted about 23.4 degrees, so as the planet orbits the Sun, Changchun leans toward the Sun for part of the year and away for the rest. When it leans toward the Sun the days lengthen and the Sun climbs higher; half a year later the opposite happens. The size of the swing depends on how far Changchun sits from the equator: the further away, the bigger the difference between the longest and shortest day.
