The spelling of the word "leap year" is straightforward. The first syllable, "leap," is pronounced /liːp/. The second syllable, "year," is pronounced /jɪə(r)/. The word "leap" means to jump or spring quickly, while "year" denotes the time it takes for the Earth to complete one revolution around the sun. A "leap year" is a year with an additional day, February 29, to account for the discrepancy between the solar year and the calendar year. It occurs every four years, except for years divisible by 100 but not by 400.
A leap year is a calendar year that contains an additional day, usually occurring once every four years. This additional day, known as a leap day, is inserted into the month of February, causing it to have 29 days instead of the usual 28. The purpose of leap years is to maintain synchronization between the calendar year and Earth's orbit around the sun, as it takes approximately 365.25 days for Earth to complete one orbit.
To compensate for this extra quarter day, a leap year is introduced. However, not every year divisible by four is considered a leap year. To determine whether a year is a leap year, the following criteria apply: the year must be divisible by four but not divisible by 100, unless it is also divisible by 400. For example, the year 2000 was a leap year because it is divisible by 400, while the year 1900 was not a leap year because although it is divisible by four, it is also divisible by 100 but not by 400.
Leap years play a significant role in keeping the calendar aligned with the astronomical seasons. By adding an extra day every four years, leap years prevent the calendar from slowly drifting out of sync with the solar year. This adjustment helps maintain seasons and various astronomical events at approximately the same time each year, ensuring consistency and accuracy.

The word "leap year" comes from the combination of two Old English words: "leap" and "year".
The word "leap" comes from the Old English word "hleapan", which means "to jump, run, or spring". The term is associated with the additional day added to the calendar during a leap year, which "jumps" over the usual arrangement of 365 days per year.
The word "year" is derived from the Old English word "gear", which means "circuit" or "revolution". It refers to the time it takes for the Earth to complete one orbit around the Sun.
Thus, the term "leap year" signifies a year that deviates from the regular pattern by including an extra day (February 29th) to adjust the calendar and effectively "jump" over an entire day in the cycle of time.
