Astronomical Affairs Department confirms autumnal equinox date and time

According to the Astronomical Affairs Department in Oman, the autumnal equinox for the year 2026 is set to occur on Wednesday, September 23. This celestial event marks the official beginning of astronomical autumn in the Northern Hemisphere, a transition point where the sun crosses the celestial equator, resulting in nearly equal lengths of day and night across the globe.

The department confirmed the specific date and timing as part of its routine monitoring of solar and lunar cycles. These calculations are essential for maintaining the accuracy of regional calendars and are regularly published by the Sultanate's scientific authorities to keep the public informed about seasonal shifts.

Following the equinox, the Northern Hemisphere will experience a gradual decrease in daylight hours as the region tilts further away from the sun, leading into the winter months. Such astronomical updates are standard practice for the department, which provides data to assist in agricultural planning, navigation, and general public awareness regarding seasonal changes within the Sultanate and the wider region.
