If the Earth's axis was vertical - every point on its surface would have the same length of day and night, no matter what time of year it was. The tilt of the axis (to about 11 degrees) means that, as the Earth rotates, and travels around the sun, the length of day shortens and lengthens throughout the year.
The earths rotational axis is tilted approx. 23 degrees from vertical The earths rotational axis remains parallel throughout its rotation around the sun, high summer (longest day) in the northern hemisphere, is when the top of the axis is at full tilt toward the sun. (shortest day in the southern hemisphere)
winter
For those in the northern hemisphere, around March 21st (and again in October) is the half way point between the shortest day (Winter solstice) around December 21st and the longest day (summer solstice) around June 21st. Its all to do with the earths tilt, March 21st, or around that time is when we have one of the equinoxes, where the earth tilt is such that it neither points away or towards the sun, the length of day is the same for the whole planet (12 hours).
Your answer depends on where you are. At the South Pole when the Earth is tilted toward the Sun, it's summer.

Mars.
Because of the earths tilt of 22.5 degrees
Earths tilt
The length of the day and the length of the seasons
Because of the earths axial tilt.

24 hours.
the tilt of the planet
The length of a day (one rotation of the earth) does not change by any significant amount. The amount of daylight received will vary according to your latitude due to the axial tilt if the earth and the earths position in its orbit around the sun
