If you want a continuous count instead of a calendar date then maybe a DS1371 32-bit counter timekeeping chip would be a better fit for your project.

Instead of having the DS1302 generate the full calendar date, then having your code turn the date parts into a count by applying a fairly elaborate set of calculations, the DS1371 could deliver you a continuous count in seconds, and you'd have a much simpler calculation to convert it to a Julian number of just a single division by the  number of seconds per day, then adjust the result with an origin offset.
