About this count
Today, Sunday, October 18, isn't counted, but September 30 is. That gives 347 days, and the count reaches 1 on Wednesday, September 29, the day before the end of September. 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(2027,9,30)-TODAY() gives the same 347 today; add 1 to count today as well.
This count to September 30, 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.
