The Roman Method of Reckoning the Year.[1] There are three ways in which the course of the year may be calculated. It can be reckoned— 1. By the revolution of the moon round the earth, twelve of which = 354 days, or a ring (_annus_), sufficiently near to the solar year to be a practicable system with modifications. 2. By the revolution of the earth round the sun i. e. 365-1/4 days; a system which needs periodical adjustments, as the odd quarter (or, more strictly, 5 hours 48 minutes 48 seconds) cannot of course be counted in each year. In this purely solar year the months are only artificial divisions of time, and not reckoned according to the revolutions of the moon. This is our modern system.
