Fun Facts About the Equinox
- During the equinox, the Sun rises almost exactly due east and sets almost exactly due west.
- The term "equinox" comes from the Latin words "aequi" (equal) and "nox" (night).
- While the equinox is often said to have exactly equal day and night, this is an approximation. The actual day and night lengths can vary slightly due to atmospheric refraction and the Sun's disc size.
How to Observe the September Equinox
While the equinox is a specific moment in time, you can observe its effects over several days:

- Monitor Day Length: Observe the changing length of daylight as days become shorter in the Northern Hemisphere and longer in the Southern Hemisphere.
- Participate in Celebrations: Many communities host events to celebrate the arrival of autumn or spring.
Understanding the timing and significance of the September Equinox enhances our appreciation of the Earth's seasons and astronomical cycles. Mark your calendars for September 22, 2025, at 18:19 UTC to observe this celestial event.
