The adoption of the Gregorian calendar occurred slowly over a period of centuries, and despite many proposals to further reform the calendar, the Gregorian Calendar still prevails as the most commonly used dating system worldwide.This is a list of major active social networking websites and excludes dating websites (see Comparison of online dating websites).In order to accomplish this, Caesar inserted an additional 10 days to the Republican calendar, making the total number of days in a year 365.He also added the intercalation of a leap day every fourth year, all in an attempt to further synchronize the Roman calendar with the solar year.The months of April, June, September, and November have 30 days, while the rest have 31 days except for February, which has 28 days in a standard year, and 29 in a leap year.
The Republican calendar later used by Rome followed Greek calendars in its assumptions of 29.5 days in a lunar cycle, and 12.5 synodic months in a solar year, which align every fourth year upon the addition of the intercalary months of January and February.
Under the Gregorian calendar, century years not divisible by 400 would not be leap years.
These changes reduced the error from 1 day in 128 years, to 1 day in 3,030 years with respect to the current value of the mean solar year.
From this point, many attempts were made to align the Republican calendar with the solar year including the addition of an extra month to certain years to supplant the lack of days in a particular year.
In 46 BC, the calendar was further reformed by Julius Caesar, introducing an algorithm that removed the dependence of calendars from the observation of the new moon.
