September 30 date facts
The next September 30 falls in the upcoming year. It is the last day of the ninth month of the year and one of the more consequential dates on the U.S. calendar, closing out the third quarter for most businesses and marking the end of the federal fiscal year.
Why count down to September 30?
September 30 carries more weight than most end-of-month dates.

That makes it one of the most closely watched dates in Washington and among federal contractors across the country.
Outside of government, September 30 signals the close of Q3 for most publicly traded companies, kicking off earnings season and triggering performance reviews, sales pushes, and financial planning for the final quarter of the year. For students, renters, and everyday planners, it also often serves as a lease renewal checkpoint, a scholarship application cutoff, or simply the last day to hit a personal goal before Q4 begins.
