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:

  • Spring: March 20-21
  • Fall: September 22-23

Most rapid change near equinoxes: 2-4 minutes daily.

Slowest change near solstices: <1 minute daily.
