Put these on your calendar next to the English month names:
- Ianuarius (January)
- Februarius (February)
- Martius (March)
- Aprilis (April)
- Maius (May)
- Iunius (June)
- Iulius or Quinctilis (July) *
- Augustus or Sextilis (August) *
- September (September)
- October (October)
- November (November)
- December (December)
* Iulius and Augustus were the new names in Imperial times. Use Sextilis and Quinctilis to be authentic to the Republic.
The first day of each month, called the "Kalends" is sacred to Iuno, so write "Kalends" on the first of each month. Write the word "Nones" on the 7th day of March, May, July, and October. Write "Nones" on the 5th day of all other months. Write the word "Ides" on the 15th day of March, May, July, and October. Write "Ides" on the 13th day of all other months. The Ides of every month were sacred to Iuppiter (Jupiter), so you can make a note of that too.
"Ater" means "unlucky" in Latin. Each day after the Kalends, Nones or Ides is "ater", an unlucky day, so write "Ater" or "Unlucky" on every day after each Kalends, Nones and Ides.
There are a lot of holidays; these are just some of the important ones:
- January Kalends: Add Ianus to Iuno on this, the first day of the year.
- January 11th and January 15th: Carmentalia, to the goddess Carmenta.
- February 13th: Parentalia, in honor of one's deceased parents.
- March 17th: Liberalia, in honor of Liber, god of agriculture.
- April 21st: Parilia, in honor of Pales, guardian of shepherds. Also, the founding day of Rome.
- May 9th, 11th and 13th: Lemuria. A festival to exorcise the restless spirits of the undead. (Similar to Japanese "Setsubun".)
- June 9th: Vestalia. In honor of Vesta, goddess of the hearth.
- July 6th through 13th: Ludi Apollinares, the "Games of Apollo", in honor of Apollo, patron of music and healing.
- September 13th: Epulum Iovis, sacred to Iuppiter (Jupiter).
- October 13th: Fontinalia, a festival to the god Fontus, who gives fresh water.
