Length of Day

Location determines the amount of sunlight an area will receive over the course of the year. Places closest to the equator do not see much variation in the length of daylight hours during all four seasons. The number of daylight hours decreases in the fall and winter the further away a location is from the equator. Between September and March, days are shorter than nights in the Northern Hemisphere than the Southern Hemisphere. From April to August, days and nights are shorter in the Southern Hemisphere.
