About September
September comes from septem, Latin for seven, because it was the seventh month of the early Roman year before January and February were added at the front.
Labor Day falls on the first Monday, and by then most US schools are back. The September equinox, on the 22nd or 23rd, starts astronomical fall in the north and spring in the south. Sapphire is the birthstone.

About this count
Each midnight takes one off the 318. Today is left out and September 1 itself is counted, so on Tuesday, August 31 the page will show 1 day to go. US clocks go back on Sunday, November 1 and forward again on Sunday, March 14, 2027, which changes the hours but not the number of days.
In Excel or Google Sheets, =DATE(2027,9,1)-TODAY() gives the same 318 today; add 1 to count today as well.
This count to September 1, 2027 was worked out on Sunday, October 18, 2026 (US Eastern time), and your browser recounts it from your own date when the page opens.
