As the long summer days shorten and kids head back to school, a cool breeze signals the arrival of September in the Northern Hemisphere, marking the beginning of fall with its colorful leaves and cooler temperatures. Meanwhile, in the Southern Hemisphere, September ushers in spring with blooming flowers and longer, warmer days as the Sun crosses the celestial equator.

September, the ninth month of the Gregorian Calendar, has 30 days and brings a unique charm to both hemispheres.

In the north, it signals the approach of colder days and the cozy traditions of autumn. In the south, it heralds the warmth and renewal of spring. Whether it’s the crispness of fall or the freshness of spring, September offers a fascinating transition filled with natural beauty and cultural celebrations.

Why September is Not the Seventh Month

September derives its name from the Latin word “septem,” which translates to seven, creating confusion as to why it is the ninth month despite its name suggesting otherwise.

Originally, the Roman calendar, attributed to Romulus around 750 BC, had ten months totaling 304 days, with a gap of approximately 61 days during winter.

  • Martius (March)
  • Aprilis (April)
  • Maius (May)
  • Junius (June)
  • Quintilis (July)
  • Sextilis (August)
  • September
  • October
  • November
  • December

This calendar was eventually deemed inaccurate and required adjustments to align more closely with the solar year. Consequently, several changes were made over time, including adding months and days.

January and February were later incorporated to account for the approximately 60 days missing from the original ten-month calendar. These additional months were inserted before March, shifting the original names of the months by two places. However, the names of the later months, including September, were not changed to reflect their new positions in the calendar.

Thus, although September comes from the Latin word for “seven,” it is the ninth month in our modern calendar due to the historical modifications made to the calendar system.

These adjustments were made by Julius Caesar (Julian calendar) and later refined by Augustus.

Equinox

In September, the equinox occurs, marking significant seasonal transitions. In the Northern Hemisphere, it is the Autumn Equinox, while in the Southern Hemisphere, it is the Vernal Equinox. The dates of the equinox can vary, falling between September 21 and September 24

During this time, the Sun crosses the celestial equator, marking the official start of autumn in the Northern Hemisphere.

During the Vernal Equinox in the Southern Hemisphere, the sun crosses the celestial equator, resulting in nearly equal daylight and nighttime hours. At this time, the moon's phases continue their regular cycle, unaffected by the equinox, while the sun's position directly above the equator signifies the balance between day and night.
