March marked a return to the active life of farming, military campaigning, and sailing. It was densely packed with
religious observances dating from the earliest period of Roman history. Because of its original position as the first month, a number of festivals originally associated with the new year occurred in March. In the
Imperial period, March was also a time for public celebration of
syncretic or
international deities whose ''
cultus'' was spread throughout the empire, including
Isis and
Cybele.
In the agricultural year
The ''
menologia rustica'' told farmers to expect 12 hours of daylight and 12 of night in March. The
spring equinox was placed March 25. The

. As a god of war, Mars was a guardian of agriculture and of the state, and was associated with the cycle of life and death. The season of Mars was felt to close in October, when most farming and military activities ceased, and the god has a second round of festivals clustered then.

"holy week" for Cybele and Attis developed in the latter half of the month, with an entry festival on the Ides, and a series of observances from March 22 through March 27 or 28. Isis had official festivals on March 7 and 20.
Dates

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 March was the 7th, and the
Ides of March was the 15th. Thus the last day of March was the ''pridie Kalendas Aprilis,'' "day before the Kalends of April". Roman counting was
inclusive; March 9 was ''ante diem VII Idūs Martias'', "the 7th day before the Ides of March," usually abbreviated ''a.d. VII Id. Mart.'' (or with the ''a.d.'' omitted altogether); March 23 was ''X Kal. Apr.'', "the 10th day before the Kalends of April."

, each day was marked with a letter to denote its religiously lawful status. In March, 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;
* QRCF (perhaps for ''quando rex comitiavit fas''), a day when it was religiously permissible for the ''rex'' (probably the priest known as the ''
rex sacrorum'') to call for an assembly;
* EN for ''endotercissus'', an
archaic form of ''intercissus'', "cut in half," meaning days that were ''nefasti'' in the morning, when
sacrifices were being prepared, and in the evening, while sacrifices were being offered, but were ''fasti'' in the middle of the day.
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
Marcus Aurelius Antoninus ( ; ; 26 April 121 – 17 March 180) was Roman emperor from 161 to 180 and a Stoicism, Stoic philosopher. He was a member of the Nerva–Antonine dynasty, the last of the rulers later known as the Five Good Emperors ...
. 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).
A ''
dies natalis'' was an anniversary such as a temple founding or rededication, sometimes thought of as the "birthday" of a deity. During the
Imperial period, some of the traditional festivals localized at Rome became less important, and the birthdays and anniversaries of the emperor and his family gained prominence as Roman holidays. On the calendar of military religious observances known as the ''
Feriale Duranum'', sacrifices pertaining to

outnumber the older festivals, but among the military the importance of Mars was maintained and perhaps magnified. The ''
dies imperii'' was the anniversary of an emperor's accession. After the mid-1st century AD, a number of dates are added to calendars for
spectacles and games ''(
ludi)'' held in honor of various deities in the venue called a "
circus" ''(ludi circenses)''. Festivals marked in large letters on extant ''fasti'', 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.
