The most "universal" timekeeping system in the Ninth World is that of the Order of Truth. It has these properties:

• A day is 28 hours long.
• Each year is 313 days long, divided into 52 weeks of 6 days each. The last day of the year is called Safe Haven, and is not counted as part of any week.
• There are 10 months in a calendar year, of 31 days each. The three days that are "missing" are counted inbetween the old and the new year.
• Calendar years are counted from the year of the founding of the order.

The names of the months are:

1. Moonlyth
2. Yorkental
3. Drebental
4. Kaizenar
5. Poizenar
6. Aftental
7. Kiltental
8. Hebendar
9. Sobendar
10. Sunlyth

The campaign starts on 13, Poizenar, in the year 413.
