^{P651:1, 57:0.1} In presenting excerpts from the archives of Jerusem for the records of Urantia respecting its antecedents and early history, we are directed to reckon time in terms of current usage -- the present leap-year calendar of 365¼ days to the year. As a rule, no attempt will be made to give exact years, though they are of record. We will use the nearest whole numbers as the better method of presenting these historic facts.

^{P651:2, 57:0.2} When referring to an event as of one or two millions of years ago, we intend to date such an occurrence back that number of years from the early decades of the twentieth century of the Christian era. We will thus depict these far-distant events as occurring in even periods of thousands, millions, and billions of years.
