The count is exclusive of the start date and inclusive of the end date: day one is January 1, 2000 plus 24 hours. Weekends and public holidays are included — for working days only, use the business days calculator.
2000 was a leap year — divisible by 400, so it kept the leap day that century years usually skip. From 1 January to 31 December 2000 is 365 days; adding the final day back makes the full year 366.
Method & sources
Day counts use the Gregorian calendar and are computed on calendar dates in UTC, so daylight-saving changes never add or remove a day. The count excludes the start date and includes the end date — the same convention as subtracting one date from another.
