September 5 is the 248th day of the year in the Gregorian calendar, with 117 days remaining until the end of the year. It is often associated with the transition from summer to autumn in the Northern Hemisphere, marking a time when many schools and universities resume classes after the summer break. Several notable events have occurred on this date throughout history.
