The Julian calendar, introduced by Julius Caesar in 46 BC, was the predominant calendar system in Europe for over 1600 years. However, by the 16th century, it became evident that the Julian calendar had a slight miscalculation in its leap year system, causing the calendar to drift out of sync with the solar year. To address this issue, Pope Gregory XIII introduced the Gregorian calendar in 1582.
The transition from the Julian to the Gregorian calendar involved skipping 10 days to realign the calendar with the solar year. This adjustment was made by declaring that October 4, 1582, would be followed by October 15, 1582. Additionally, the Gregorian calendar introduced a more accurate leap year rule, which states that a year is a leap year if it is divisible by 4, except for years that are divisible by 100 but not by 400.
