Solar Leap Year Calculator determines whether a given solar year is a leap year or not.
Solar Leap Year
A solar leap year is a concept introduced to correct the fact that a solar year is not exactly 365 days but approximately 365.2425 days. To minimize this discrepancy, an extra day is added every four years, making a leap year 366 days long. This adjustment ensures that seasons and calendar dates remain aligned.
The rules for determining a leap year are as follows:
- A year is a leap year if it is divisible by 4.
- However, if the year is divisible by 100, it is not a leap year.
- But if the year is divisible by 400, it is a leap year.
In a leap year, February has 29 days. Normally, February has 28 days, but in a leap year, one extra day is added.
Examples:
The year 2024 is divisible by 4, so it is a leap year. Therefore, February 2024 has 29 days, and the year has a total of 366 days.
The year 1900 is divisible by 100, so it is not a leap year. Therefore, February 1900 has 28 days, and the year has a total of 365 days.
The year 2000 is divisible by 400, so it is a leap year. Therefore, February 2000 has 29 days, and the year has a total of 366 days.
Solar Common Year
A solar common year refers to a year with 365 days. According to the leap year rules, any year that is not a leap year is considered a common year. Common years contain 365 days, ensuring that the addition of leap years every four years helps maintain alignment between seasons and calendar dates.
In a common year, February has 28 days.
Example:
The year 2023 is not divisible by 4, so it is not a leap year. Therefore, February 2023 has 28 days, and the year has a total of 365 days.
