24. Although there are 100 years in a century, and a leap year is normally every 4 years, and 100 divided by 4 is 25, the year 2300, which is the last year of the 23rd century is not a leap year, due to the rules for leap years. It is divisible by 100, but not by 400.
There are 24 leap years in the 21st century. Here they are:200420082012201620202024202820322036204020442048205220562060206420682072207620802084208820922096
The 23rd century starts on 2201, which from 2017 is 184 years away.
25 cause a leap year occurs every 4 years
182,621,250 days. This answer assumes that every fourth year is a leap year except for century years, where every fourth century is a leap year.
31,536,000 year x 100 = 3,153,600,000 in a century + 25 leap years in a century at 2,160,000 seconds = 3,155,760,000 in a century counting leap days.
if no leap years: 52.56 minutes if all leap years: 52.704 minutes if standard century: 52.59492 minutes
Look for a perpetual calendar on the Net, that should help. You would think there would be 25 but I am not sure they didn't skip a leap year in the year 2000 (which was the final year of the 20th century, not the first of the current one).
A century consists of 100 years. Typically, a year has 365 days, so 100 years would equal 36,500 days. However, considering leap years, which add an extra day every four years, a century generally has 36,525 days, accounting for 25 leap years. Thus, the total can vary slightly depending on how many leap years occur in that specific century.
Including 2000, there are 243 leap years from 2000 through 3000. Most centuries have 24 leap years, every four years from the fourth through the 96th year of the century. Only once every four centuries is the last year of the century also a leap year (like the year 2000).
Generally, every fourth year is a leap year. However, "century" years like 1800 and 1900 are not leap years unless they are divisible by 400. So 2000 _was_ a leap year.
18627 or 18628 days, depending on the incidence of leap years. It is possible to have 18626 days if you have a non-leap-year century.
