How many total days were there in the years 2001 through 2004?

There were a total of 1462 days.

365 + 365 + 365 + 366 ( 2004 was a leap year)

1461 days

The answer is 365+365+365+366=1461 days.

Not really... mind the leap year (Like EP said, 2004 is a leap year )

There were

Mondays, Tuesdays, Wednesdays, Thursdays, Fridays, Saturdays, Sundays, holidays, workdays. That is 9 days.

I am sure you can think of a few more.
