Thirteen months of twenty-eight days, and one day that belongs to no week.
Every month starts on Lanius and ends on Dardonis, so a given date falls on the same weekday every month and every year. The 29th of Castus, Terminalia, is the festival of boundaries and sits outside the week; the next day is 1 Glacius, a Lanius again.
The winter solstice falls on Terminalia, the last day of the year, and the seasons turn every 91 days from there: the vernal equinox on 7 Vernus, the summer solstice on 15 Solaris, and the autumnal equinox on 22 Vindemius.
The moon waxes and wanes once a month: new on the 1st, full on the 15th. Holidays tied to a weekday fall on a fixed date, since the weeks never shift. Lanius is the first working day; Dies Danae and Dardonis are the rest days.
Years are counted ab Capitali condita (A.C.C.), from the founding of Capital. The empire held Orden for about 1,700 years and fell about 3,000 years ago, and the present year is 4679 A.C.C.
