September 4

Calendar and seasonal context

As an early-September date, September 4 is often close to seasonal transitions: the meteorological end of summer and the approach of the autumnal equinox later in the month in the Northern Hemisphere. For historical research, events recorded before widespread adoption of the Gregorian calendar may appear with different dates in older (Julian) sources; therefore calendar conversion is sometimes necessary when comparing records.

History and notable events

Over centuries, September 4 has been the day of diverse political, cultural and scientific occurrences. Historians often cite it as the traditional date for the deposition of the last Western Roman emperor in the 5th century, and many other regional events have been commemorated on this date. Because specific lists vary by country and discipline, detailed chronologies typically present events with contextual notes about the calendar used at the time.

Observances, birthdays and trivia

• Modern observances on September 4 include local or religious feast days in some Christian calendars and civic commemorations in different countries.
• Several well-known people have birthdays on September 4 — for example, the internationally known singer Beyoncé was born on this date in 1981.
• The date occasionally coincides with the U.S. federal Labor Day when that holiday falls on the first Monday of September, affecting public events and schedules.

Because September 4 appears every year, it functions as a convenient marker in annals, almanacs and anniversary lists. For more comprehensive, date-specific lists of events, births and observances, consult specialized chronologies or national calendars that compile entries tied to this day.
