What is a leap year ?How is it caused ?
Answers
Answer:
It takes approximately 365.25 days for Earth to orbit the Sun — a solar year. We usually round the days in a calendar year to 365. To make up for the missing partial day, we add one day to our calendar approximately every four years. That is a leap year.
Answer:
a year, occurring once every four years, which has 366 days including 29 February as an intercalary day
A leap year is a calendar year that contains an additional day added to keep the calendar year synchronized with the astronomical year or seasonal year
Leap years happen because a planet's orbit around the Sun (year) and rotation on its axis (day) are not perfectly in line. This is true of almost every other planet in our solar system. Mars, for example, has more leap years than regular years! A year on Mars is 668 sols, or Martian days.
