Full Answer

As the summer progresses, the rate of daylight loss increases. Around the time of the autumnal equinox in late September, when the day and night are exactly equal, the days grow shorter by about three minutes per day. However, the speed of this process reverses itself shortly after that point, and by the winter solstice, when the nights are longest, daylight again decreases by about one minute per three days. A similar rate occurs with the increase of daylight between the winter and summer solstices. The particular loss of daylight per day also depends on the location's latitude.

  • Q:

    Why is June 21 the longest day?

    A:

    The summer solstice is the longest day of the year because the Earth's tilt is greatest toward the Sun on that day. The axis of the Earth is tilted 23.5 degrees from the vertical as it follows its orbital path. This means that for part of the year, the Northern Hemisphere is tilted closer to the Sun, giving that half of the planet more daylight per revolution.

    Why is June 21 the longest day of the year?

    A:

    June 21st is the longest day of the year in the Northern Hemisphere because it is the summer solstice, which describes the tilt of the Earth's axis. This phenomenon is only observable outside of the tropics as it is the tilt of the Earth that alters the duration of light exposure of any one point on the surface.
