- The countdown counts calendar days from today to September 21, 2027. The start date is excluded and the end date is included. Dates use Eastern Time (America/New_York).
- The live countdown runs to midnight at the start of September 21, 2027 in Eastern Time (America/New_York). A countdown day is 24 hours, so a daylight-saving change can make it differ from the calendar-day count by an hour.

- U.S. business days exclude Saturday, Sunday and observed nationwide federal closures; individual employer and state schedules are not included.
