What religions use the lunar calendar?
Judaism uses lunar and solar together. They add an occasional leap-month to reconcile it to the solar calendar. Islam uses the lunar calendar exclusively. Druids use the Lunar calendar; and Christians use the Lunar calendar to calculate Easter every year. Some Satanists and Pagans use the Lunar Calendar. In fact the Lunar calendar is used by everyone to some degree.
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.
How would someone age if they were born on a leap year?
People born on February 29 add one to their legal age on March 1, if the year is not a leap year.
Why are leap years included in the calendar?
a leap year is february 29th and it appears every 4 years on the gregorian calendar. it exists to keep seasons where they are in relation to the year. because a year is 365.25 days wheras you can only have 365 days in a year, so to account for that .25 they add an extra day every four 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.

Why do you add a extra day to the calendar every four years?
It is because a year is actually 365 1/4 days long, therefore if we had every year as only 365 days the year would gradually move and we would eventually have summer during the winter and vice versa. Thus putting an extra day into a year every four years keeps everything in balance.Answer:A year is really 365.2422 gays long so we have to adjust the calendar to keep it accurate (those quarter days and a bit add up) and in accord with the solstices and equinnoxes. Every one thinks it's simple, in the Georgian calendar we add an extra day every 4 years - not quite right. The real rule is:Every year that is evenly divisible by four is a leap year;of those years, if it can be evenly divided by 100, it is NOT a leap year, unlessthe year is evenly divisible by 400. Then it is a leap year.A day is added to the calendar every 4 years (Leap Year) so that the calendar matches the earth's revolutions around the sun.Because we have a leap year, I think we have a leap year next year. ---------------------------------------------------------------------------------Basically because it takes 1 year and 1/4 of a day for the Earth to make one orbit of the Sun. Thus we need to add 1 day to our year every 4 years to keep the calender correct.
