Days become shorter from the Summer Solstice in June [the longest day of the year] through the Winter Solstice in December [the shortest day of the year] , when the days begin growing longer again. [At the Vernal and Autumnal Equinoxes, midway between the solstices, the days and nights are of equal lengths.]
It all depends on your latitude. The closer you are to the equatorial latitudes, the more your days are equal in numbers closer to 12. In all other latitudes, the further you are up towards the poles, the larger the difference is of daytime and nighttime. At the equator, the days and nights are pretty much the same in summer and winter. But near the poles, summer is always in daylight and winter is always in darkness.
Which planet/moon/space-object are you talking about?
These are the spring and autumn equinoxes, and are days when the daylight and darkness are equal.
No. At an equinox, which happens in March and September, the amount of daylight and darkness are about equal.
Only on the 2 equinox's which are March 21 and September 21.
March 20th or 21st
The length of daylight or nighttime hours does not affect the seasons, but the seasons affect the length of daytime and nighttime hours. During the summer, the earth is tilted more toward the sun, resulting in longer daytime hours. During the winter months, the earth is tilted away from the sun, resulting in shorter days and longer nights.
Technically, one. The other days may suspect to be full of daylight but truly, they are shorter.
on the moon daylight last 13.65 days because if you divide 27.3 by 2 you get 13.65 days on the monn.
There are 1407.5 hours of daylight on Mercury which is 56.646 earth days!!
March equinox and September equinox : Daylight and darkness are of equal length on both the Vernal Point (Spring/March 20th 2011) and the Autumnal Point (Autumn/September 23rd 2011) .
