szökév

The Hungarian word "szökév" translates to "leap year" in English. A leap year is a calendar year that contains an extra day, February 29th, making it 366 days long instead of the usual 365. This extra day is added to keep the calendar year synchronized with the astronomical year, or the time it takes for the Earth to orbit the sun. Without leap years, the seasons would gradually drift out of sync with the calendar over time.

The Gregorian calendar, which is the most widely used calendar system today, determines leap years using a specific set of rules. A year is a leap year if it is divisible by 4. However, years divisible by 100 are not leap years, unless they are also divisible by 400. For example, the year 2000 was a leap year because it is divisible by 400, but the year 1900 was not a leap year because, although divisible by 4 and 100, it is not divisible by 400. The term "szökév" reflects this cyclical addition of an extra day to correct for the Earth's orbital period.
