Labor Day has passed and fall is about to begin, on September 23 this year to be exact, so I’d like to share a bit of trivia with you.
Say goodbye to summer in the northern hemisphere. Astronomically, the September equinox is the autumnal, or fall, equinox marking the end of summer and the beginning of fall (autumn). The fall season ends on December Solstice, when astronomical winter begins. For meteorologists, on the other hand, fall in the northern hemisphere begins about 3 weeks before the September equinox on September 1 and ends on November 30. In the southern hemisphere, the September equinox is the vernal (spring) equinox. The September equinox is also known as the vernal or spring equinox in the southern hemisphere and is considered by astronomers as the first day of spring there. Equinoxes are not day-long events, even though many choose to celebrate all day. Instead, they occur at the moment the sun crosses the celestial equator – the imaginary line in the sky above the earth’s equator. At this instant, earth’s rotational axis is neither tilted away from nor towards the sun. In 2019, the sun crosses the celestial equator from north to south on September 23, at 07:50 UTC (Coordinated Universal Time – the explanation of this abbreviation is another story in itself). Because of time zone differences, the equinox will take place on September 22 at locations that are at least 12 hours or more behind UTC. These include the uninhabited Baker Island and Howland Island.
While September equinox usually occurs on September 22 or 23, it can very rarely fall on September 21 or September 24. A September 21 equinox has not happened for several millennia. However, in the 21st century, it will happen twice – in 2092 and 2096. The last September 24 equinox occurred in 1931, the next one will take place in 2303.
The equinox dates vary because of the difference between how the Gregorian calendar defines a year (365 days) and the time it actually takes for Earth to complete its orbit around the sun (about 365 and 1/4 days). This means that each September equinox occurs about 6 hours later than the previous years September Equinox. This eventually moves the date by a day. NOTE: These dates are based on the time of the equinox in UTC. Due to time zone differences, locations ahead of UTC may celebrate the September equinox a day later and locations behind UTC may celebrate it a day earlier.
