Daylight Hours FAQ: 10 Most Googled Questions Answered
Daylight hours refer to the period between sunrise and sunset. This duration changes throughout the year based on season and geographic location.
Earth's 23.5° axial tilt causes uneven sunlight distribution. Your hemisphere receives less direct sunlight in winter (shorter days) and more in summer (longer days).
Northern Hemisphere: June 20-22 (summer solstice).
Southern Hemisphere: December 21-23.
Near polar circles, the sun doesn't set for 24 hours.
Northern Hemisphere: December 21-22 (winter solstice).
Southern Hemisphere: June 20-21.
The closer to poles, the more extreme variations:
- Equator: ~12-hour days year-round
- Polar regions: Midnight sun/polar nights occur
Miami's lower latitude means:
- Winter days are longer than NY's
- Summer days are slightly shorter
During equinoxes:
