The Julian calendar was introduced by Julius Caesar in 46 BC, and it was the predominant calendar in the Western world for over 1600 years. This calendar had a year of 365 days divided into 12 months, with an additional day added every four years to account for the discrepancy between the solar year and the calendar year.
However, the Julian calendar had a slight inaccuracy in its leap year calculation, which led to the gradual misalignment of the calendar with the solar year. By the 16th century, the Julian calendar was out of sync with the seasons, prompting the need for a new calendar system.

The Final Date in the Julian Calendar
The final date in the Julian calendar was October 4, 1582. This date was followed by the introduction of the Gregorian calendar, which was implemented by Pope Gregory XIII to correct the inaccuracies of the Julian calendar. In order to realign the calendar with the solar year, ten days were skipped, and the leap year rule was adjusted to eliminate the error.
Despite the transition to the Gregorian calendar, some Orthodox churches and countries continued to use the Julian calendar for religious and cultural reasons. As a result, the Julian calendar is still in use in some regions, particularly for calculating the date of Easter.
