De la echinocțiu la solstițiu: Câte ore de lumină pierdem zilnic până la cea mai scurtă zi din an

Equinoxes and solstices are significant astronomical events that signal seasonal changes, linked to Earth's movement around the Sun. The autumn equinox occurs twice a year, with the next one on September 23, 2026, marking the start of autumn in the Northern Hemisphere. During this time, daylight hours decrease, leading to longer nights until the winter solstice on December 21. The article also explains the differences between equinoxes and solstices, including the concept of 'equilux', where day and night are of equal length. Additionally, it discusses how the tilt of Earth's axis affects daylight duration, with variations depending on latitude, especially around equinoxes and solstices.
