The fundamental difference between the Julian and Gregorian calendars is this:
- The Julian calendar year is exactly 365.25 days.
- The Gregorian calendar year is exactly 365.2425 days.
While the difference is small (10.8 minutes), the effect is cumulative. The Julian calendar was adopted in 45 BC. Over the course of the next 1,200 years, the date of the vernal equinox had advanced by ten days. Since the Roman Catholic Church used the equinox to set the date of Easter, they considered it undesirable for it to be continually getting earlier in the year, so a change to the calendar was ordered by Pope Gregory XIII in 1582.
The cumulative difference between the two calendars continues to increase, by three days in every four centuries. By the time the British Empire, including its American colonies, adopted the Gregorian calendar in 1752, the difference was 11 days. The Julian calendar is currently 13 days behind the Gregorian calendar. On March 1, 2100, the difference will become 14 days.

What is a difference between Gregorian and Julian calendar?
The short answer to the difference between the Julian and Gregorian calendars is three days per 400 years. In every 400-year period the Julian calendar has 100 leap years while the Gregorian calendar has 97. The years that are leap years in the Julian calendar but not in the Gregorian calendar are years evenly divisible by 100 but not evenly divisible by 400. So 1600 was a leap year, 1700, 1800 & 1900 were not leap years, 2000 was a leap year, 2100, 2200 & 2300 are not leap years, and 2400 is a leap year.The time it takes Earth to go from a solstice or equinox around the sun and back to the same solstice or equinox is about 365.24219 days. The average year of the Julian calendar is 365.25 days. The difference between those two numbers caused the calendar to drift one day every 128 years. By the time Pope Gregory XIII authorized a fix, the northern hemisphere's vernal (spring) equinox had drifted to around the 10th of March. The removal of three days from every 400 years changed the average calendar year to 365.2425 days, which changed the error from one day every 128 years to one day every 3200 years.
Was the Gregorian calendar based on the moon?
Although the Gregorian calendar has "months", it is not in any way governed by the phases of the moon. It is strictly a solar calendar, so its emphasis is to remain in sync with the solstices and equinoxes, the characteristics of the Earth's orbit of the sun. Only lunar calendars, like the Muslim calendar, and lunisolar calendars, like the Jewish calendar, are based on the phases of the moon, with each month beginning at the time of the new moon.
Why was the Julian calendar replaced by the gregorian calendar?
The Julian calendar was replaced by the Gregorian calendar to address inaccuracies in the calculation of leap years. The Gregorian calendar introduced a more precise leap year rule to better align the calendar year with the solar year, reducing the discrepancies that had accumulated over time.

Which are the twele months in gregorian year?
The twelve months in the Gregorian year are January, February, March, April, May, June, July, August, September, October, November, and December. They are exactly the same months as the months in the Julian Year. The difference between the Gregorian Calendar and the Julian Calendars have to do with the calculation of leap years. In The Gregorian Calendar, leap years do not occur in years ending in 00 unless the number preceding the 00 is divisible by 4. This keeps the calendar the same for sunrise and sunset at about the same throughout the year. The Julian Calendar makes no exception for the difference in the difference between the slight difference between the solar year and the calendar year. It is far easier for a computer to calculate dates for ancient astronomical phenomena using a Julian Calendar than using a Gregorian Calendar. It is of course then quite easy for a computer to translate the date to a Gregorian Date.

Is the leap year in the Julian calendar?
Yes, beside securing January 1st as the first day of the year, the only difference between the Gregorian and Julian calendars is that in the Julian calendar every 4th year is a leap year, but in the Gregorian calendar the 100th, 200th and 300th years of every 400-year period are not leap years. Every 400 years is only three days shorter in the Gregorian calendar than in the Julian calendar, but that makes it about 25 times more accurate.
What do the Gregorian calendar and Julian calendar have in common?
almost everything... The major difference between the two calendars is the Julian calendar has 100 leap years in every 400 years, and the Gregorian calendar has 97 leap years in every 400 years. That makes the average length of a Julian calendar year 365.25 days and the average length of a Gregorian calendar year 365.2425 days. As a result, it takes only about 128 years for the Julian calendar to accumulate a full day of error, but for the Gregorian calendar to accumulate a full day of error takes about 3200 years.
