The first leap year in the modern sense was 1752, when 11 days were 'lost' from the month September with the adoption of the Gregorian calendar by Britain and her colonies. After 1752 we adopted the system still in use today where an additional day is inserted in February in years wholly divisible by 4, other than years ending in 00 with the exception of those divisible by 400 which are still leap years (like 2000). This is certainly not the first use of leap years, the Julian calendar we used before 1752 had a simpler system of leap years, and remember, no calendar is universal.
Leap years are US election years. 2006 was not a leap year.
Is this the year of Summer Olympics and a US presidential election ? Yes: This year is a Leap Year. No: This year is not a Leap Year.

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.
