B(2024·盐城市鹿鸣路初级中学一模)
新素材 科普知识 The year 2024 is a leap year, which means it will have 366 days. It is different from the typical(平常的) number of 365 days in a year. The extra day, called leap day, will be February 29.

Leap years happen every four years(with some exceptions) and get their name from the idea that they make us “leap” over a day of the week. In typical years, if your birthday were on a Monday one year, it would be on a Tuesday the following year. However, if your birthday were on a Monday and the following year was a leap year, then your birthday would leap over Tuesday and fall on a Wednesday.
Leap years were established(创建) in 46 BCE by the Roman leader Julius Caesar. He created the Julian calendar, which called for a leap day every four years to make sure the calendar continued to match up with the seasons. In 1582, the Julian calendar was replaced by the Gregorian calendar(公历), which is used by most of the world today and also includes leap years.
The Gregorian calendar is based on the Earth’s movement around the Sun, but the Earth’s yearly orbit(轨道) does not take an exact 365 days. Instead, the Earth’s orbit is 365 days and nearly six hours, so a leap day is added to account for those extra hours.
Without leap years, the Gregorian calendar and the Earth’s orbit would not line up correctly over time, and neither would the calendar and the seasons of the year. In 100 years, they would be off by 25 days. After about 700 years, summers would start in December.
