Iconography of the month
The
Calendar of Filocalus illustrated the month of August with a seasonal representation of summer's heat. A peacock fan overhangs a nude male who drinks from a large bowl, with his cast-off garment in the top right corner. The

beside him is sealed with a flower and in one extant copy is inscribed ''ZLS'', probably a mistaken transcription for the Greek exhortation ''zeses'', "to your health". Three mature gourds or melons are another seasonal motif.
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 August was the 5th, and the Ides the 13th. The last day of August was the ''pridie Kalendas Septembris,'' "day before the Kalends of September". Roman counting was
inclusive; 9 August was ''ante diem V Idūs Sextīlis'' (''ante diem V Idūs Augustas''), "the 5th day before the Ides of August," usually abbreviated ''a.d. V Id. Sext.'' (''a.d. V Id. Aug.''), or with the ''a.d.'' omitted altogether. The Julian calendar reform added two days to Sextilis; thus on the pre-reform calendar, 23 August was ''VIII Kal. Sept.'', "the 8th day before the Kalends of September," but on the Julian calendar ''X Kal. Sept.'', "the 10th day before the Kalends of September".

, each day was marked with a letter to denote its religiously lawful status. In August, 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;
* 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.

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 ''
