Fall Equinox: Date and Science Explained

Fast Summary

• The autumn equinox in the Northern Hemisphere begins on Monday, September 22 at 2:19 p.m. EDT (18:19 UTC).
• At this time, the sun’s position crosses southward over Earth’s equator, resulting in nearly equal durations of day and night worldwide.
• Precise daylight on the equinox varies slightly due to atmospheric light bending, with days lasting about 12 hours and a few extra minutes across different latitudes.
• Equinoxes have cultural importance; various ancient structures align with shadows and sunlight during this celestial event (e.g.,Pyramid of Kukulcán in Mexico and Angkor Wat in Cambodia).
• Fall lasts until December 21, marking the winter solstice when days begin to shorten further until spring arrives on March 20 next year.

Indian Opinion Analysis
India experiences the effects of global astronomical transitions like equinoxes indirectly by influencing seasonal patterns crucial for agriculture and monsoons. Observing such dates offers insights into India’s alignment within Earth’s wider geophysical systems-helpful for farmers planning sowing or harvesting cycles around reduced daylight as autumn settles in parts of northern India.
