Day and night would always be the same.

11hours 28minutes

of both night and day in all seasons

(a day only has 23hours and 56minutes in it)

Answer 3

approximately 12 hrs in both summers and winters

Answer 4

the same.... tilt has nothing to do with time of day...

Answer 5

I think in some places it would always be night and in others it would always be day. But it would never change.

Answer 6

Without a tilted axis, and assuming you are asking about equator, see below from wikipedia:

"On the Equator, the length of day is not exactly 12 hours all the year round, but rather — due to atmospheric refraction and the size of the Sun — exceeds 12 hours by about 7 minutes each day."

I assume they refer to the fact that during sunset and sunrise, the light from the sun is bent slightly as it approaches or recedes from the horizon line. Note that this also assumes a flat horizon; no big mountains allowed.

Answer 7

All the time there would be equinox. Meaning everywhere on the Earth both night and day would be of almost the same length. You can read the wiki why the day would be a bitsy longer.

There is also an exception on the poles where it would be daytime 24/7
