Understanding the Basics
A standard year in the Gregorian calendar, which is the most widely used calendar system worldwide, consists of 365 days. However, it’s not always that straightforward. Here’s a breakdown:
- Common Year: 365 days
- Leap Year: 366 days
What is a Leap Year?
A leap year occurs every four years to keep our calendar aligned with the Earth’s revolutions around the Sun. Here’s how to determine if a year is a leap year:
- If the year is divisible by 4, it’s a leap year.
- However, if the year is also divisible by 100, it’s not a leap year.
- Unless the year is also divisible by 400, then it is a leap year.
For example, 2020 and 2024 are leap years, but 2100 will not be a leap year.
Why Do We Need Leap Years?
The Earth actually takes approximately 365.242190 days to orbit the Sun. Without leap years, our calendar would slowly drift out of sync with the seasons. Adding an extra day every four years (with some exceptions) helps keep our calendar aligned with the astronomical year.
