While scientific knowledge attributes shorter days to the Earth's axial tilt, the Ethiopian Orthodox Tewahedo Church interprets celestial and seasonal changes, including the shortening of days, through a unique theological lens rooted in its biblical canon and spiritual tradition.
Scientific explanation for shortening days
Earth's axial tilt: The primary cause for the changes in day length throughout the year is Earth's 23.5-degree axial tilt. As the Earth revolves around the sun, the Northern and Southern Hemispheres alternately tilt toward or away from the sun.
