As long as the Earth's mass doesn't change, neither does
its gravity, regardless of what day it is.
Gravity does not directly cause day and night. Earth's rotation on its axis is what causes day and night. As Earth rotates, different parts of the planet are either facing towards the Sun (daytime) or away from the Sun (nighttime). Gravity is the force that keeps objects, including Earth, in orbit around the Sun.
a day on mars is 24 hours, 39 minutes and 35 seconds compared to earth.
Solar day (24 hours for the Earth): about 116.75 Earth days. Sidereal day (rotation period, about 23 hours and 56 minutes for the Earth): about 243 Earth days. Year: about 224.7 Earth days.
Not this year. Earth Day is the same date in the Gregorian calendar each year, and the Gregorian calendar is not synchronized with the lunar calendar at all.
Yes. When the distance between the object's centers of mass increases, the force of gravity weakens (this can be measured experimentally on Earth at low elevations and high elevations with a sensitive pendulum and an accurate clock).
It doesn't. For instance ... Earth & Venus have almost the same gravity yet Venus' day is about a year long Whereas Mars has but a quarter of Earth's gravity and its day is almost identical.
Earth will always have gravity for gravity is a result of mass.

because the gravity of the earth sampak to the moon;)
because the earth is polluted and they want to have at least one day to take care about the earth.
because of the full gravity on earth
There are different definitions for day, but on average the Martian day is 38 minutes longer than the Earth day.
24 Hours, 59.178 seconds A single day doesn't give you enough experience to judge this planet though. You should visit it for at least a year ^_^
Earth Day is celebrated in April on the 22nd day. Most countries have some kind of Earth Day celebration on April 22 each year.
Year: 88 Earth days. Rotation period (sidereal day): 58.6 Earth days. Solar day: 176 Earth days.
April 22th
a day on mars is 24 hours, 39 minutes and 35 seconds compared to earth.
