    julian-day-calendar-1583

    Integer algorithms from J. Scaliger in 1583 for calendar date "math"

    Josephus Justus Scaliger created the concept of Julian Day Number (named in honor of his father Julius) because he was a historian interested in resolving historical dates based on different calendars. He brought together several calendars including the Gregorian calendar in 1583 and chose a base date of 4713 BC January 1 from which to number all days. He chose that date as one common to the then common calendars he wanted to reconcile. He also devised an algorithm using integer calculations only to convert a date in the modern Gregorian calendar to a Julian Day Number and back again. Using Scaliger's algorithms, you can calculate the number of days between any two calendar dates by converting each date into its unique Julian Day Number and then finding the difference in days between them. ...
