For more than you ever wanted to know about Julian Dates, see:

However, it is worth noting that a Julian Date calendar (which only counts
days, not weeks, months, or years), can start from any arbitrary starting
date. In that regard, many of the major software vendors (Microsoft, AICS
Research, etc.) start their calendars at midnight, Dec 31 1899, so that Jan 1
1900 is day 1 of the calendar.
