The autumnal equinox, also known as the September equinox, marks the astronomical start of fall in the Northern Hemisphere. It occurs when the Sun crosses the celestial equator, moving from the Northern Hemisphere to the Southern Hemisphere. The term “equinox” comes from the Latin words “equi” (equal) and “nox” (night), signifying the day when the length of day and night are approximately equal.
In the Northern Hemisphere, the September equinox typically falls around September 22 or 23. In 2024, the autumnal equinox will occur on Monday, September 23rd, at 04:30 Universal Time (UTC). Different time zones will observe the equinox at varying local times.
The autumnal equinox holds cultural and symbolic significance in various societies. It marks the changing seasons, bringing cooler temperatures and shorter days. In many cultures, it is associated with the harvest and the transition from summer to winter.

Time (UTC): 04:30
The autumnal equinox in 2024 will occur at 04:30 Universal Time (UTC). UTC is the primary time standard by which the world regulates clocks and time. It is based on the mean solar time at the Greenwich meridian in England.
-
Coordinated Universal Time
UTC is the successor to Greenwich Mean Time (GMT). It was introduced in 1972 to provide a more precise and stable timekeeping system. UTC is now the basis for civil time in most countries around the world.
-
Atomic timekeeping
UTC is based on the International Atomic Time (TAI) scale, which is maintained by the International Bureau of Weights and Measures (BIPM). TAI is the most accurate timekeeping system available, based on the natural vibrations of cesium atoms.
-
Time zones
The world is divided into 24 time zones, each of which is one hour apart. UTC is the basis for all time zones, and local times are calculated by adding or subtracting a certain number of hours from UTC.
-
Daylight saving time
Many countries observe daylight saving time (DST) during the summer months. DST involves advancing clocks by one hour, so that more daylight hours fall during the evening. The autumnal equinox marks the end of DST in many countries, when clocks are turned back one hour.
Understanding the concept of UTC is important for accurately determining the time of the autumnal equinox in different parts of the world. Time zones and daylight saving time can affect the local time of the equinox, so it is essential to refer to UTC for the precise astronomical moment.
Equal day and night
The autumnal equinox is characterized by the equal length of day and night all over the world. This occurs because the Earth’s axis is tilted neither towards nor away from the Sun.
-
Axial tilt
The Earth’s axis of rotation is tilted at an angle of approximately 23.5 degrees. This tilt causes the different seasons as the Earth orbits the Sun throughout the year.
-
Equinoxes
During the equinoxes, the Earth’s axis is not tilted towards or away from the Sun. As a result, the Sun’s rays fall directly on the Earth’s equator, and the day and night are of equal length everywhere on the planet.
-
Duration of daylight
On the autumnal equinox, the Sun rises due east and sets due west. The duration of daylight is approximately 12 hours at all latitudes.
-
Symbolism
The equal length of day and night during the equinoxes has symbolic significance in many cultures. It represents a time of balance and harmony between light and darkness.
The autumnal equinox is a reminder of the Earth’s dynamic relationship with the Sun and the changing seasons. It is a time to appreciate the beauty and balance of nature.
Start of fall (Northern Hemisphere)
The autumnal equinox marks the astronomical start of fall in the Northern Hemisphere. It is a time of transition, as the days grow shorter and the nights longer. The changing seasons bring about beautiful foliage, crisp air, and a sense of renewal.
As the Earth orbits the Sun, the Northern Hemisphere gradually tilts away from the Sun. This causes the Sun’s rays to strike the Northern Hemisphere at a lower angle, resulting in shorter days and cooler temperatures.
The autumnal equinox is a reminder that the seasons are constantly changing. It is a time to reflect on the past and look forward to the future. It is also a time to enjoy the beauty of the changing landscape and the abundance of nature’s harvest.
In many cultures, the autumnal equinox is celebrated with festivals and traditions. These celebrations often involve giving thanks for the harvest and preparing for the coming winter.
