How many days were there in 1997 - 2010?

5,113 days. 1997 was not a leap year, so it had 365 days. 1998 was not a leap year, so it had 365 days. 1999 was not a leap year, so it had 365 days. 2000 was a leap year, so it had 366 days. 2001 was not a leap year, so it had 365 days. 2002 was not a leap year, so it had 365 days. 2003 was not a leap year, so it had 365 days. 2004 was a leap year, so it had 366 days. 2005 was not a leap year, so it had 365 days. 2006 was not a leap year, so it had 365 days. 2007 was not a leap year, so it had 365 days. 2008 was a leap year, so it had 366 days. 2009 was not a leap year, so it had 365 days. 2010 was not a leap year, so it had 365 days. This gives us 11 non-leap years, or 11 years with 365 days, which is 11(365), and 3 leap years, or 3 years with 366 days. This is 3(366). So the number of days in 1997 - 2010 would be represented by the expression 11(365) + 3(366), which gives us 5,113 days.
