Nearly every four years, we add an extra day to the calendar in the form of February 29, also known as Leap Day. Put simply, these additional 24 hours are built into the calendar to ensure that it stays in line with the Earth's movement around the Sun.

Answer 2

Answer:

The calendar year was originally meant to start in March with the vernal equinox, so that’s the first day of spring,” Rachel Ward-Maxwell, a staff astronomer with Ontario Science Centre, told CTV’s Your Morning.

“And so February was the last day of the year, so that’s why the extra date would be added in February to make sure that the first day of spring was always aligned with the right time.”

Generally a leap year happens every four years, but there are exceptions.

A year may be a leap year if it is evenly divisible by four. Years that are divisible by 100, century years such as 1900 or 2000, cannot be leap years unless they are also divisible by 400.

For this reason, the years 1700, 1800 and 1900 were not leap years, but the years 1600 and 2000 were.

This rule about years divisible by 100 years and 400 years was added with the introduction of the Gregorian calendar in 1582.
