What is the difference between Julian and Gregorian calendars?
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.
