When is the First Day of Fall? When is the September (Autumnal) Equinox?
Need to know the exact date of of the First Day of Fall this year?
On the equinoxes the Sun shines directly on the equator and the length of day and night is nearly equal – but not quite. The September or Autumnal Equinox is when the Sun crosses the celestial equator, moving from north to south. This date is considered to be the first day of Fall.

Please note: The dates given on this page are based on Coordinated Universal Time (UTC), which for practical purposes is equivalent to Greenwich Mean Time (GMT). While Autumn starts and ends at the same moment in time all over the Northern Hemisphere, the date of the First Day of Autumn differs from location to location depending on a location's time zone. For more details see the explanations below.
The start and end dates for autumn given on this page are the dates of astronomical autumn in the Northern Hemisphere and are based on Coordinated Universal Time (UTC), which for practical purposes is equivalent to Greenwich Mean Time (GMT - the time zone of the United Kingdom). While autumn starts and ends at the same moment in time all over the Northern Hemisphere, the date and local time differ from place to place depending on the year and a location's time zone. For locations that are ahead of UTC (further east) it may fall on the day after, and for locations that are behind UTC (further west) it may fall on the day before. To find out the exact date and time of autumn 2022 in your area use this seasons calculator.
Meteorologists, on the other hand, define seasons based on climatic conditions and the annual temperature cycle. It is important for them to be able to compare the same period of time in different years. The length of the astronomical seasons varies between 89 and 93 days, while the length of the meteorological seasons is less variable and is fixed at 90 days for winter in a non-leap year (91 days in a leap year), 92 days for spring and summer, and 91 days for autumn. While the exact definition of a season's timing and length can differ in different areas based on local conditions, in most of the Northern Hemisphere meteorological autumn is generally defined as the three months of September, October and November, with the season starting on September 1 and ending on November 30. There is no "official rule" which definition of autumn to use, and different countries adhere to different conventions. Most of North America and Europe use astronomical autumn, while Australia and New Zealand use meteorological autumn (however, as these countries are in the Southern Hemisphere, the seasons are opposed and autumn there lasts from March to May). In other cultures, eg. in the traditional Chinese calendar and in Celtic traditions, the September equinox is considered to be roughly the middle of autumn. Further reading:- Autumn on Wikipedia
