<p>At lat +50.0 on Jun 21 and lat -50.0 on Dec 21 is the time between sunrise and sunset exactly the same?  And so on throughout the parallels and the days of the year?</p>

<p>If not can you explain why?  I once read something about the earth's wobble on its axis means that daylight length is not symmetrical north to south.</p>

Solstices occur in June & December, there are large differences between daylight hours during solstices. It's more likely that equal daylight hours would occur during the equinoxes in March & September

Fred I'm talking about comparing daylight hours between north and south.  I'm not asking if the the solstice daylight is longer than equinox daylight.

Is daylight time symmetrical between northern and southern hemisphere?
