About this count
Each midnight takes one off the 317. 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 317 today; add 1 to count today as well.
This count to September 1, 2027 was worked out on Monday, October 19, 2026 (US Eastern time), and your browser recounts it from your own date when the page opens.
