## Description

Converts a date from the French Republican Calendar to a Julian Day Count. These routines only convert dates in years 1 through 14 (Gregorian dates 22 September 1792 through 22 September 1806). This more than covers the period when the calendar was in use.

## Return Values

The julian day for the given french revolution date as an integer.
