Which city experience equal lengths of days and nights throughout the year?

The amount of day and night doesn’t change much around places near the Equator throughout the year—each one lasts around twelve hours. This is because the Equator is a line that stands perpendicular to the sun’s rays. In the case of Nairobi in Kenya, the city is actually very close to the equator and receives days that are almost, but not quite, 12 hours long during the entire calendar year. However, there is only a difference of approximately 9 minutes between the longest and shortest day of the year. But in exact terms, what this means is any point on the equator follows this pattern. The Earth tilts at about 23.5 degrees on its side as it rotates, and that is precisely why we have seasons. The reason we have spring, summer, autumn, and winter is that different parts of the world are tilting towards or away from the sun. The Equator, meanwhile, is midway between the North and the South Pole and always faces the sun. This means that the sun’s path divides day and night into two equal parts, about 12 hours each.
