The imperial calendar was adopted as a means to standardize the recording of dates across the Empire. Although some scholars at the time still recorded events using the former Roeman calendar, that proved an exception rather than the rule for recording dates. In the imperial calendar dates are denominated “Anno Imperialis” translated roughly as “in the year of the Emperor” or “Imperial Year”. Preceding dates are denominated “Anno Ante” or translated loosely as “before the coming of the Emperor”. All dates can thus be measured in imperial years for aiding in chronology which necessitates the application of such measurement standards.
