Astronomers even today use the "Julian day" count to avoid confusion
with changing calendars. The Julian day count is the number of days
since noon (GMT) on January 1, -4712, i.e., January 1, 4713 BC. This
scheme was proposed by Julius J. Scaliger  in 1583 (so has nothing
to do with Julius Caesar).
