لماذا نغير الساعة مرتين كل عام؟ أستاذ فلك يوضح الهدف من التوقيت الصيفي والشتوي

ما يعرفه ريفو عن الخبر

  • يتم تغيير الساعة مرتين سنويا للاستفادة من ساعات ضوء النهار خلال فصل الصيف.
  • يمثل التوقيت الشتوي التوقيت المحلي الأصلي لمصر والذي يتقدم على توقيت جرينتش بساعتين.
  • يتم تغيير الساعة في نهاية الأسبوع لتقليل اضطراب مواعيد المواطنين والتزاماتهم اليومية.
  • يبدأ تطبيق التوقيت الشتوي في مصر من منتصف ليل الخميس 29 أكتوبر 2026 بتأخير الساعة 60 دقيقة.

مع بدء تطبيق التوقيت الشتوي في مصر، عاد الحديث عن أسباب تغيير الساعة مرتين سنويًا، والهدف من العمل بالتوقيت الصيفي خلال أشهر الصيف، وعلاقته بحركة الشمس وطول ساعات النهار، وهو ما أوضحه الدكتور أشرف تادرس، أستاذ الفلك بالمعهد القومي للبحوث الفلكية والجيوفيزيقية.
