What is a Leap Year?
A leap year is a year that contains an extra day, February 29, in order to keep the calendar year synchronized with the astronomical year. This additional day is added to the calendar every four years. The purpose of a leap year is to ensure that the calendar remains accurate by accounting for the fact that it takes the Earth approximately 365.2422 days to complete its orbit around the sun.
Why Do We Have Leap Years?
Without leap years, the calendar would slowly drift out of alignment with the seasons. Over time, this discrepancy would result in holidays and seasons occurring at different times of the year. Leap years help to correct this by adding the extra day, ensuring that the calendar stays in sync with the Earth’s orbit.
Examples of Leap Years
Some examples of leap years include 2020, 2024, 2028, 2032, and so on. These years have a total of 366 days, with February having 29 days instead of the usual 28.
Impact of Leap Years
Leap years have various impacts on different aspects of life, including business, finance, and even personal life. For example, some financial institutions use leap years to adjust interest rates and payment schedules, while some people born on February 29 celebrate their birthdays only once every four years.
