According to Dr. Ashraf Tadrus, an astronomy professor at the National Institute for Astronomical and Geophysical Research, Egypt's winter time in 2026 will begin on October 29. This change involves setting clocks back by 60 minutes to align with the country's standard time, which is two hours ahead of Greenwich Mean Time. The primary goal of this seasonal time change is to make better use of daylight during the longer summer days.
The decision to implement winter time is aimed at optimizing energy consumption. During summer, Egypt's daylight hours stretch to around 14 hours, and by adjusting the clock forward, residents can make the most of natural daylight, thereby reducing the need for artificial lighting and ultimately conserving energy. Conversely, during winter, daylight hours are significantly shorter, lasting around 10 hours, and reverting to standard time allows people to start their day closer to sunrise.
Dr. Tadrus explained that the concept of winter and summer time is not applicable in equatorial regions, where daylight hours remain relatively consistent throughout the year. In these areas, the temperature remains high during the day and drops significantly at night, regardless of the season. The length of daylight and nighttime is approximately equal in these regions, with each lasting around 12 hours.
The implementation of winter time in Egypt is designed to synchronize daily activities with the solar cycle. By setting clocks back, residents can enjoy more daylight during their waking hours, particularly during the winter months when daylight is scarce. This change also aims to minimize disruptions to daily life, with the clock change typically occurring on a weekend to minimize the impact on work and school schedules.
Egypt's geographical location, at a significant distance from the equator, results in pronounced seasonal variations. The country's climate is characterized by hot summers and mild winters, with daylight hours varying substantially throughout the year. The introduction of winter time allows Egyptians to adapt to these seasonal changes and make the most of the available daylight.
According to Dr. Tadrus, the change in clock time is also influenced by the Earth's axial tilt and its orbit around the Sun. As the Earth rotates, different parts of the planet experience varying levels of sunlight, resulting in the changing seasons. The implementation of winter time in Egypt is a response to these astronomical phenomena, aimed at optimizing daily life and energy consumption.
The upcoming switch to winter time in Egypt is expected to have a positive impact on the country's energy efficiency and daily routines. By aligning the clock with the solar cycle, residents can enjoy more daylight during their waking hours, reduce their energy consumption, and adapt to the changing seasons. The change is set to occur on October 29, 2026, and will involve setting clocks back by 60 minutes.
Key points
- Egypt will implement winter time in 2026 on October 29, setting clocks back by 60 minutes to align with the country's standard time.
