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.
Does gravity affect a person's height and why?
I think the length of day affects humans by sleeping earlier or later, they can also be affected by having different emotions. But I think I'm wrong...
During the Autumn equinox the length of the day and night are nearly equal. The length of the day on the equinox is approximately twelve hours.
yes. All the way around the equator the day length doesn't change.
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 length of day does not affect the season.
No.
Yes. Given a constant for gravity, the period of the pendulum is a function of it's length to the center of mass. In a higher gravity, the period would be shorter for the same length of pendulum.

The length of the day would change if either the rotational speed of the the planet or the orbital distance from the sun changed. However, if you mean what factors affect the length of daylight, then that is different.
The period of a pendulum is independent of its length. The period is determined by the acceleration due to gravity and the length of the pendulum does not affect this relationship. However, the period of a pendulum may change if the amplitude of the swing is very wide.
no
Day length does not affect the flowering of day-neutral plants as they flower independently of the length of daylight. Day-neutral plants are not influenced by variations in day length and will flower based on other factors like age or overall plant health.
the tilt of the planet
No, the force of gravity does not affect the period of a pendulum. The period of a pendulum is determined by the length of the pendulum and the acceleration due to gravity. Changing the force of gravity would not change the period as long as the length of the pendulum remains constant.
Does gravity affect a person's height and why?
The amplitude of a pendulum does not affect its frequency. The frequency of a pendulum depends on the length of the pendulum and the acceleration due to gravity. The period of a pendulum (which is inversely related to frequency) depends only on these factors, not on the amplitude of the swing.
