What does leap year men?

The Earth takes 365 days to rotate around the sun right? Wrong. It actually takes 365 days, and 1/4th of a day. So every four years, you become a day off. As time goes on, the calendar gets more, and more out of whack. Scientists first noticed this when they were celebrating the New Year in April, and they thought, 'that's not right.' They came up with a solution: every four years, add an extra day and 'leap forward' to get back with the calendar. Since February only has 28 days normally, they decided this month would be best to add that day. Happy Leap Year!


Why did they throw away the old calendar?

We changed from the Julian calendar to the Gregorian calendar because it was out of synch with the solar calendar. The Pope consulted an astronomer and it was decided to add leap years to correct the problems. Catholic countries changed in 1582. However Germany did not until 1700 and Great Britain waited until 1752. Russia did not change until 1918.

What is the reason of leap year?

Leap years are necessary because the actual length of a year is 365.242 days, not 365 days, as commonly stated. Basically, leap years occur every 4 years, and years that are evenly divisible by 4 (2004, for example) have 366 days. This extra day is added to the calendar on February 29th.

What year was the last February 30?

The last time February had 30 days was in the year 1712. This anomaly occurred in Sweden when they transitioned from the Julian to the Gregorian calendar. In order to catch up with the rest of Europe, Sweden decided to add an extra day in February that year. Since then, February has consistently had 28 or 29 days in leap years.

Who first started the practice of adding days to the calendar?

The Romans "invented" the calendar as we know it. Without researching it, the first calendar with leap days, with the 12 months as we know the calendar, was the Julian calendar named after Julius Caesar. It had an error of about 3 days in 400 years. This calendar was replaced by the much more accurate Gregorian calendar by decree of Pope Gregory in the late 1600's in the Catholic countries and accepted by most Protestant and other countries in the 1700's. There was an adjustment of 12 or 13 days in the calendar at that time. The Gregorian calendar is the calendar we use today. Prior to the Julian calendar, days were added as needed in all calendars including the one which began in March and had only 10 months ! This is why the 12th month, December, comes from the Latin word for ten. The Mayan and Chinese calendars, among others, were known for their accuracy and would have had to add days also.
