There's more evidence for rural usage of the Roman monthly dating system than the yearly - unfortunately, their monthly system is even more bizarrely fucked, even post-Julian reforms. "It is currently three days after the Ninth (this is the 7th day of the month, of course)" very intuitive

Still, considering the importance of the calendar to (as you mentioned) trade and the like, and the widespread distribution of monthly calendars, it, unlike dating the exact year, was clearly widely used.
