In Latin records, dates are often written out. Numbers generally end with -o when used in a date. For example:

Anno Domini millesimo sescentesimo nonagesimo quarto et die decimo septimo mensis Maii [In the year of (our) Lord one thousand six hundred ninety-four, and on the seventeenth day of the month of May]

To understand Latin dates, use the following lists as well as the preceding "Numbers" section.
