Day and Night Get Equal Billing on Tuesday. A Guide to the Fall Equinox – WTOP News
- On Tuesday, Sept. 22, 2026, the autumn equinox marks the official astronomical beginning of fall across the Northern Hemisphere at 8:05 p.m. EDT.
- Derived from Latin words meaning "equal night," the event occurs as Royal Museums Greenwich noted, "the Sun passes the celestial equator," resulting in nearly equal day and night.
- Cooler air has settled across parts of the Northeast, with the first hints of fall color appearing, as shorter days trigger the annual transformation of leaves into red, orange and yellow.
- The National Weather Service and AccuWeather meteorologists are tracking a developing coastal storm capable of producing heavy rain and strong winds to portions of the East Coast later this week.
- Future seasonal milestones include the winter solstice on Dec. 21, 2026, marking the shortest day of the year, and daylight saving time ending on Nov. 1.
