If you’re wondering whether 2023 is a leap year, then read on. We will explore everything about leap years, including how they are calculated and any other questions you may have.

1. What is a leap year? Why do we have leap years?

What is a leap year?

A leap year occurs when there are 366 days in the Gregorian calendar, with a repeating cycle of an extra day every four years. In the lunar calendar, a leap year has 13 months instead of the usual 12.

The Earth takes approximately 365 days and 6 hours to orbit the Sun. In a regular year, we count 365 days, leaving those extra 6 hours unaccounted for. After four years, those extra hours add up to a full day, hence the need for a leap year in the Gregorian calendar.

The lunar calendar, on the other hand, differs significantly from the Gregorian calendar. To ensure that a lunar year corresponds to a full set of moon phases and aligns with the four seasons, an extra month is added to the lunar calendar approximately every three years.

However, because the lunar year is still slightly shorter than the Gregorian year, a more precise adjustment is made by adding a leap month every 19 years.

2. How to calculate a leap year

A leap year in the Gregorian calendar occurs every four years, when February has 29 days instead of the usual 28. For a year to be a leap year, it must be divisible by four. Additionally, years ending in ’00’ must be divisible by 400 to be considered a leap year.

For example, the year 2020 was a leap year because it is divisible by four. However, the year 2023 is not a leap year in the Gregorian calendar, so February 2023 will only have 28 days.

To determine if a specific year in the lunar calendar is a leap year, divide that year by 19. If the remainder is 3, 6, 9, 11, 14, 17, or 0, then that year is a leap year in the lunar calendar.

For example: To check if the year 2023 is a leap year in the lunar calendar, we divide 2023 by 19, which gives us a quotient of 106 and a remainder of 9. Therefore, the year 2023 is a leap year in the lunar calendar.

How do we determine which lunar month is the leap month?

In a leap year in the lunar calendar, the leap month is the month that does not contain a solar term, which is when the sun reaches a particular position relative to the earth.

There are 12 solar terms in a year: Spring Equinox, Grain Rain, Summer Solstice, Minor Heat, Major Heat, Autumn Equinox, Frost’s Descent, Winter Solstice, Minor Snow, Major Snow, Spring Begins, and Rain Water.

If multiple months in a leap year do not contain a solar term, then the first month after the Winter Solstice will be the leap month. However, the first and last months of the year are never considered leap months in the lunar calendar.
