Note: The Gregorian calendar was introduced in 1582 to correct the drift in the Julian calendar. The difference between the two calendars increases over time.
Here’s how it works: The tool takes a date you input (in YYYY-MM-DD format) and converts it between the Julian and Gregorian calendars. The Gregorian calendar, introduced in 1582, corrected the drift in the Julian calendar by skipping 10 days. Over time, the difference between the two calendars grows. The converter calculates this difference in days and displays both dates side by side.
For example, if you enter October 15, 1582 (Gregorian), the tool will show you October 5, 1582 (Julian), because of the 10-day correction. It’s like having a time machine for dates!
