The Romans did not number days of a month sequentially from the 1st through the last day. Instead, they counted back from the three fixed points of the month: the
Nones (5th or 7th, depending on the length of the month), the
Ides (13th or 15th), and the
Kalends (1st) of the following month. The Nones of June was the 5th, and the Ides the 13th. Roman counting was
inclusive; June 9 was
ante diem V Idūs Iunias, "the 5th day before the Ides of June," usually abbreviated
a.d. V Id. Iun. (or with the
a.d. omitted altogether). The last day of June was the
pridie Kalendas Quinctilis (
pridie Kalendas Iulias after July was renamed), "day before the Kalends of July". The modern equivalent of this date was June 29 on the pre-Julian calendar, but June 30 on the Julian, because June was one of the months to which a day was added in realigning with astronomical time. June 23 was thus
VIII Kal. Quinct., "the 8th day before the Kalends of Quinctilis", during the
Republican era, but
IX Kal. Iul., "the 9th day before the Kalends of July", in the
Imperial era. On the calendar of the Republic and early
Principate, each day was marked with a letter to denote its religiously lawful status. In June, these were: •
F for
dies fasti, days when it was legal to initiate action in the courts of
civil law; •
C for
dies comitalis, a day on which the Roman people could hold assemblies
(comitia), elections, and certain kinds of judicial proceedings; •
N for
dies nefasti, when these political activities and the administration of justice were prohibited; •
NP, the meaning of which remains elusive, but which marked
feriae, public holidays. By the late 2nd century AD, extant calendars no longer show days marked with these letters, probably in part as a result of calendar reforms undertaken by
Marcus Aurelius. The unique Q.ST.D.F. of June 15 stands for , when it was a religious obligation to remove dirt from the
Temple of Vesta.
Varro specifies the act of sweeping '. Days were also marked with
nundinal letters in cycles of
A B C D E F G H, to mark the "market week" (these are omitted in the table below). Festivals marked in large letters on extant , represented by festival names in all capital letters on the table, are thought to have been the most ancient holidays, becoming part of the calendar before 509 BC. A
dies natalis was an anniversary such as a temple founding or rededication, sometimes thought of as the "birthday" of a deity. Unless otherwise noted, the dating and observances on the following table are from
H.H. Scullard,
Festivals and Ceremonies of the Roman Republic. Scullard places the
Taurian Games on June 25–26 on a five-year cycle, but other scholars believe these
ludi had no regular date and were held as a crisis ritual when needed. After the Ides, dual dates are given to represent both the earlier calendar, when June had 29 days and July was called
Quinctilis, and the 30-day month of the Julian calendar. ==References==
