There are 24 leap years in the 21st century. Here they are:
25 cause a leap year occurs every 4 years
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.
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.
The years divided by 100 are not leap years unless these are divisible by 400. So 19th century has only 24 leap years but 21st century has 25 as year 2000 was a leap year.
A century is made of 100 years. That is longer than one year, whether it is a normal year or a leap year.

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).

Yes! It was a century leap year. Other century leap years are 1600 and 2000. The next one will probably be 2400, and along with another century leap year, 2800, that is true. The next century leap year will occur in 2400. Century leap years always start on a Saturday and the February 29 intercalation in these days is always a Tuesday to being that year.
Only century years divisible by 400 qualify to be a leap year. Years divisible by 4 but by 100 are NOT leap years, thus 1700, 1800, and 1900 were not leap years but 2000 was. 2100, 2200 and 2300 will not be leap years but 2400 will be.
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.
