Daylight Hours FAQ: 10 Most Googled Questions Answered
1. What are daylight hours?
Daylight hours refer to the period between sunrise and sunset. This duration changes throughout the year based on season and geographic location.
2. Why are days shorter in winter and longer in summer?
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).
3. When is the longest day of the year?
Northern Hemisphere: June 20-22 (summer solstice).
Southern Hemisphere: December 21-23.
Near polar circles, the sun doesn't set for 24 hours.
4. When is the shortest day of the year?
Northern Hemisphere: December 21-22 (winter solstice).
Southern Hemisphere: June 20-21.
5. How does latitude affect daylight hours?
The closer to poles, the more extreme variations:
- Equator: ~12-hour days year-round
- Polar regions: Midnight sun/polar nights occur
6. Why do New York and Miami have different day lengths?
Miami's lower latitude means:
- Winter days are longer than NY's
