Sunrise Times by Region on December 23, 2025
Sunrise times on December 23, 2025 vary considerably across different regions. In London (GMT timezone), sunrise occurs at 8:05 AM with a day length of 7 hours and 49 minutes. In Tennessee, USA, sunrise happens at 7:42 AM local time, providing approximately 9 hours and 45 minutes of daylight. These variations reflect the different latitudes and their relationship to the sun's position during the winter solstice period.
High-latitude locations experience even more dramatic sunrise timing. In By, Norway (located at higher northern latitude), sunrise occurs at 9:07 AM with only 5 hours and 42 minutes of daylight. Conversely, locations in the Southern Hemisphere like World's End, Antarctica, experience sunrise at 3:01 AM with nearly 20 hours of daylight, demonstrating the extreme seasonal differences between hemispheres.
Winter Solstice Impact on Sunrise Patterns
December 23, 2025 falls just two days after the winter solstice (December 21), when the Northern Hemisphere experiences its shortest day and latest sunrise of the year. The winter solstice marks the point where Earth's axial tilt is farthest from the sun in the Northern Hemisphere, resulting in the sun's lowest arc across the sky and the latest sunrise times. This astronomical event has been observed and celebrated by cultures worldwide for thousands of years.
The impact of the winter solstice on sunrise times is most pronounced at higher latitudes. In northern regions, sunrise times continue to shift slightly later even after the solstice date, with the latest sunrise often occurring a week or two after December 21. This phenomenon, known as the equation of time, occurs because Earth's orbit is elliptical and its axial tilt creates a complex relationship between solar time and clock time.
Using Sunrise Information for Daily Planning
Knowing accurate sunrise times helps with numerous daily activities and planning needs. Photographers use sunrise forecasts to plan golden hour sessions when the low-angle sunlight creates warm, flattering light. Commuters can adjust travel times based on visibility conditions, and outdoor enthusiasts can schedule activities during optimal daylight hours. Accurate sunrise data is essential for anyone whose schedule depends on natural light availability.
Modern technology makes accessing sunrise information straightforward, with numerous websites and applications providing precise times for any location. These tools account for factors like elevation, atmospheric refraction, and local geography to deliver accurate predictions. Whether you're planning a morning jog, a photography expedition, or simply want to understand your local daylight patterns, sunrise time data provides valuable information for optimizing your daily routine during the winter season.
