Roman Calendar

The Roman Calendar Revised by Julius Caesar in 46/45 BC (“Julian Calendar”) He increased the calendar from 355 days to 365 days He’s the reason our months today have 30 or 31 days (Feb. has always been shorter)

Julian vs. Gregorian By 1582, the Julian calendar was about 10 days out of alignment due to some small errors Pope Gregory XIII revised the calendar in 1582 to correct this problem (Gregorian Calendar) Fun fact: Britain (and its colonies) didn’t adopt the Gregorian Calendar until 1752! Wed. Sept. 2, 1752, was followed by Th., Sept. 14, 1752 in America!

How the Roman Calendar Worked The month names we use today come from the Latin month names. Romans did not number the days of the month like we do. Romans used 3 reference days each month to count down their dates.

Reference Days Kalendae: the Kalends, the 1 st of the month (where we get the word “calendar”) Nonae: the Nones, the 5 th day of the month except for March, May, July and October when they’re the 7 th day Idus: the Ides, the 13 th day of each month except for March, May, July, and October when they’re the 15 th day

Writing Dates a.d. NN = ante diem NN (on the ‘n’th day before the nomen/named day) “a.d. III Kal Nov” = “on the 3 rd day before the Kalends of November” (Oct. 30) Always count inclusively (start your count with the reference day) Pridie = “the day before” (prid Kal Ian = Dec. 31)

Naming Years Years were named after the 2 consuls elected for that year: “in the consulship of Marcus Batiatus and Quintus Secundus” Years could also be named “ab urbe condita” or AUC: “from the founding of the city” (754/753 BC).

Example of Years "Claudius was born... on the Kalends of August in the consulship of Iullus Antonius and Fabius Africanus,..." (Suetonius Claudius II.i) We know from other Roman records these 2 guys were consuls in a.u.c. 744… so that’s about 10 BC on our calendar.

Days of the Week Dies Solis (day of the Sun)---Sunday Dies Lunae (day of the Moon)---Monday Dies Martis (day of Mars)---Tuesday Dies Mercuris (day of Mercury)---Wednesday Dies Iovis (day of Jove/Jupiter)---Thursday Dies Veneris (day of Venus)---Friday Dies Saturni (day of Saturn)---Saturday

Telling Time Each day was divided into 12 hours (horae), from sunrise to sunset. Hours were numbered: prima, secunda, tertia, etc. (first, second, third…) In the summer, hours would be longer than in the winter since days were longer.
