A leap year is a year containing one extra day in order to keep the calendar year synchronized with the astronomical or seasonal year. For example, in the Gregorian calendar (common calendar), February in a leap year has 29 days instead of the usual 28, so the year lasts 366 days instead of the usual 365.
There is no year 0 in our calendar; 1 B.C. is a leap year.
No, odd-numbered years are never leap years in either the Gregorian calendar or the Julian calendar.
In a Leap Year one day is added to the calendar - February 29.
No, it wasn't a leap year under The Julian or Gregorian calendar.
It is the Gregorian calendar which we use today
Because 1500 is a century , so we should check whether it is divisible by 400 not by 4 alone. Since it is not divisible by 400 its not a leap year.1500 WAS actually a leap year, the Gregorian calendar didn't commence until the year 1600.

The 2000 calendar will repeat in 2028. This was a leap year and leap year calendars generally repeat every 28 years.
11th September is the 254th day of the year on a Gregorian calendar, assuming it is not a leap year. In a leap year, it would be the 255th day of the year.
