The Julian calendar was proposed in 46 BC by (and takes its name from) Julius Caesar, as a reform of the earlier Roman calendar, which was largely a lunisolar one. [2] It took effect on 1 January 45 BC, by his edict.
At noon on Saturday, 7 October 1867 (Julian), the date changed to Friday, 18 October 1867 (Gregorian). Although the Julian calendar was 12 days behind the Gregorian calendar, only 11 days were skipped because Alaska also moved from the Eurasian side of the International Date Line to the American side.

A leap year every 4 years adds an extra day to February making it 29 days long. First to adopt the new calendar in 1582 were France, Italy, Poland, Portugal and Spain. Turkey was the last country to officially switch to the new system on January 1st, 1927.

- Conversion Between Julian and Gregorian Calendars
The Gregorian calendar, also known as the Western or Christian calendar, is the most widely used calendar in the world today. Its predecessor, the Julian calendar, was replaced because it did not correctly reflect the actual time it takes the Earth to circle once around the Sun, known as a tropical year. In the Julian calendar, a leap daywas added ...
Over the centuries since its introduction in 45 BCE, the Julian calendar had gradually drifted away from astronomical events like the vernal equinox and the winter solstice. To make up for this error and get the calendar back in sync with the astronomical seasons, a number of days had to be dropped when the Gregorian calendar was adopted. For examp...
The papal bull issued by Pope Gregory XIII in 1582 decreed that 10 days be skipped when switching to the Gregorian calendar. However, only five countries adopted the new calendar system that year—namely, Italy, Poland, Portugal, Spain, and most of France. Since the discrepancy between the Julian calendar year and the astronomical seasons kept growi...
In total, more than three centuries passed until the Gregorian calendar had been adopted in all countries, from 1582 to 1927. The table below shows when the calendar reform occurred in some countries, including the first and the last.
The delay in switching meant that countries followed different calendar systems for a number of years, resulting in differing leap year rules. In the Gregorian calendar, most years that are evenly divisible by 100 are common years, but they are leap years in the Julian calendar. This meant that the years 1700, 1800, and 1900 were leap years in coun...
The Swedish Empire, roughly comprising the areas of today’s Sweden and Finland, even had a “double” leap year in 1712. Two days were added to February, creating February 30, 1712, after the leap day in 1700 had erroneously been dropped, and the calendar was not synchronized with either the Julian or the Gregorian system. By adding an extra leap day...
In some non-western countries, the calendar reform took on many different guises to accommodate differing cultural and historical contexts. For example, Japan replaced its lunisolar calendar with the Gregorian calendar in January 1873but decided to use the numbered months it had originally used rather than the European names. The Republic of China ...
Currently, the Julian calendar is 13 days behind the Gregorian calendar. So, to convert from the Julian calendar to the Gregorian calendar, add 13 days; to convert in the opposite direction, subtract 13 days. The gap between the two calendar systems will increase to 14 days in the year 2100. Topics: Calendar, History
The Julian calendar was introduced by Julius Caesar in 45 BC. It was in common use until the 1500s, when countries started changing to the Gregorian Calendar. However, some countries (for example, Greece and Russia) used it into this century, and the Orthodox church in Russia still uses it, as do some other Orthodox churches.
Eventually, non-Catholic countries did begin to adopt the Gregorian calendar. The Protestant regions of Germany and the Netherlands switched in the 17th century. Great Britain and the territories of the British Empire followed suit in 1752, spreading the Gregorian calendar around the globe.
