About Julian Dates

The Julian Day number is a continuous count of days since the beginning of the Julian Period on January 1, 4713 BC. It's widely used in astronomy and scientific applications.

The Modified Julian Day (MJD) is the Julian Day minus 2,400,000.5, making it easier to work with modern dates.
