As an expert in the field of calendrical studies, I can provide a detailed explanation regarding the determination of leap years. The Gregorian calendar, which is the most widely used civil calendar today, has specific rules to determine which years are considered leap years.
Leap years are important because they help to synchronize the calendar year with the solar year, which is the time it takes for the Earth to complete one orbit around the Sun. This period is approximately 365.2425 days. To account for the extra 0.2425 days, an extra day is added to the calendar every four years, making that year 366 days long instead of the usual 365. This extra day is added to the month of February, which is why February has 29 days in a leap year instead of the usual 28.
However, not every year that is divisible by 4 is a leap year. To refine the system, an additional rule was introduced: a year that is divisible by 100 is not a leap year unless it is also divisible by 400. This rule corrects for the fact that a year is not exactly 365.2425 days long but rather approximately 365.2422 days. By omitting three leap years every 400 years, the calendar remains in closer alignment with the solar year.
Now, let's apply these rules to determine if the year 2400 is a leap year:
1. Divisibility by 4: The year 2400 is divisible by 4 (2400 ÷ 4 = 600), which is the first condition for a leap year.
2. Divisibility by 100: The year 2400 is also divisible by 100 (2400 ÷ 100 = 24), which would normally disqualify it from being a leap year.
3. Divisibility by 400: The year 2400 is divisible by 400 (2400 ÷ 400 = 6), which overrides the second rule and qualifies it as a leap year.
Based on these rules, the year 2400 is a leap year because it satisfies the conditions of being divisible by 4 and also by 400.
The statement provided, "So 2000 and 2400 are leap years but 1800, 1900, 2100, 2200, and 2300 are not," is partially correct. The year 2000 is indeed a leap year because it is divisible by 400, which makes it a leap year despite also being divisible by 100. However, the years 1800, 1900, 2100, 2200, and 2300 are not leap years because they are divisible by 100 but not by 400.
In conclusion, the year 2400 is a leap year according to the rules of the Gregorian calendar. It is important to understand these rules to accurately determine leap years, as they are crucial for maintaining the calendar's alignment with the Earth's orbit around the Sun.

So 2000 and 2400 are leap years but 1800, 1900, 2100, 2200 and 2300 are not. Apart from that, every year divisible by 4 (2012, 2016, 2020, 2024, etc.) is a leap year.
