Gregorian Calendar - Months of The Year

Months of The Year

English speakers sometimes remember the number of days in each month by memorizing a traditional mnemonic verse:

Thirty days hath September,

April, June, and November.

All the rest have thirty-one,

Excepting February alone,

Which hath twenty-eight days clear,

And twenty-nine in each leap year.

For variations and alternate endings, see Thirty days hath September.

A language-independent alternative used in many countries is to hold up one's two fists with the index knuckle of the left hand against the index knuckle of the right hand. Then, starting with January from the little knuckle of the left hand, count knuckle, space, knuckle, space through the months. A knuckle represents a month of 31 days, and a space represents a short month (a 28- or 29-day February or any 30-day month). The junction between the hands is not counted, so the two index knuckles represent July and August.

This method also works by starting the sequence on the right hand's little knuckle, then continuing towards the left. It can also be done using just one hand: after counting the fourth knuckle as July, start again counting the first knuckle as August. A similar mnemonic can be found on a piano keyboard: starting on the key F for January, moving up the keyboard in semitones, the black notes give the short months, the white notes the long ones.

The origins of English naming used by the Gregorian calendar:

• January: Janus (Roman god of gates, doorways, beginnings and endings)
• February: Februus (Etruscan god of death) Februarius (mensis) (Latin for "month of purification (rituals)" it is said to be a Sabine word, the last month of ancient pre-450 BC Roman calendar). It is related to fever.
• March: Mars (Roman god of war)
• April: "Modern scholars associate the name with an ancient root meaning 'other', i.e the second month of a year beginning in March."
• May: Maia Maiestas (Roman goddess)
• June: Juno (Roman goddess, wife of Jupiter)
• July: Julius Caesar (Roman dictator) (month was formerly named Quintilis, the fifth month of the calendar of Romulus)
• August: Augustus (first Roman emperor) (month was formerly named Sextilis, the sixth month of Romulus)
• September: septem (Latin for seven, the seventh month of Romulus)
• October: octo (Latin for eight, the eighth month of Romulus)
• November: novem (Latin for nine, the ninth month of Romulus)
• December: decem (Latin for ten, the tenth month of Romulus)
