How this countdown is calculated
The day count is the difference between midnight tonight and midnight on December 18, 2026, so a countdown of one day means the date arrives tomorrow. Hours, minutes, and seconds come from the exact time remaining in your own time zone.
Business days skip every Saturday and Sunday plus the ten US federal holidays. That number is useful for shipping estimates, filing deadlines, and notice periods, which is why it sits alongside the plain day count above.
Leap years are handled automatically. Because December has a fixed number of days, December 18 lands on a different day of the week most years. The table above shows which one.
