The Julian calendar, introduced by Julius Caesar in 46 BC, was a reform of the Roman calendar. It was based on a 365-day year divided into 12 months, with an additional day added every four years to account for the extra quarter of a day in the Earth’s orbit. The Julian calendar was used in Western Europe for over 1600 years until it was replaced by the Gregorian calendar in the 16th century.
To calculate today’s date in the Julian calendar, you need to know the current date in the Gregorian calendar. First, determine the number of days that have elapsed since the beginning of the Julian calendar (January 1, 4713 BC). Then, add the number of days in the Gregorian calendar to get the equivalent date in the Julian calendar. For example, if today is January 1, 2022, you would calculate the Julian date by adding 2,459,191 (number of days from January 1, 4713 BC to January 1, 2022) to get the Julian date.
