Answer:-

  • First leap year=2000
  • Last leap year=2100

Total years=2100-2000=100years

Total leap years:-

\\ \sf\longmapsto \dfrac{100}{4}

\\ \sf\longmapsto 25

Leap year:-

  • Leap year falls in every four years.
  • it falls because Earth takes exactly 365days and 6 hours to complete a revolution .
  • We count only 365
  • Rest 6hours combined in every 4year with a day

Answer:

A century is 100 years

If a century year is divisible by 400, then that year is a century leap year. If a century year is just divisible by 4 & 100, but not 400, that year is not a leap year. The original years that are divisible by 4 are common leap years. If you were born on a leap year & if you were born on February 29, your actual birthday on a common year is March 1, but some people decided to celebrate a person birthday on February 28 if that year isn’t a leap year.

4 - Nonexistent leap year

100 - Nonexistent year

200 - Nonexistent year

300 - Nonexistent year

600 - Not a leap year

700 - Not a leap year

800 - 1st existent century leap year

900 - Not a leap year

1000 - Not a leap year

1100 - Not a leap year

1200 - A leap year

1300 - Not a leap year

1400 - Not a leap year

1500 - Not a leap year

1600 - A leap year

1700 - Not a leap year

1800 - Not a leap year

1900 - Not a leap year

2000 - A leap year

2100 - Not a leap year

Since every 4 years is a leap year & every 400 years is a century leap year, 1 full year is 365.25 days; therefore, 4 years is equivalent to 1,461 days.

If a century year is divisible by 400, a century has 25 leap years; therefore, an original century has 24 leap years
