These names actually carried through to European languages fairly closely, and in English the names of Sunday, Monday and Saturday made it straight through. The other four names in English were replaced with names from Anglo-Saxon gods. According to Encyclopedia Britannica :. Sign up for our Newsletter! Mobile Newsletter banner close.

The Romans started with a month calendar in B.

What does Greenwich Mean Time mean? Can you tell the time with flowers? When did time begin? This light-hearted, illustrated miscellany from Royal Observatory Greenwich goes a long way to answering some of these questions and also presents a whole range of other amazing facts and figures which show the influence of time on our daily lives The Romans did not have weekdays in the same sense as our Monday, Tuesday, etc. Originally, the month and the markers were based on the moon.
At the time of their early kings, Roman months were of a length identical to the lunar cycle. Each month was divided into sections that ended on the day of one of the first three phases of the moon: new, first quarter or full. All days were referred to in terms of one of these three moon phase names, Kalends, Nones or Ides. At that time a pontifex priest was assigned to observe the sky.
When he first sighted a thin lunar crescent he called out that there was a new moon and declared the next month had started. For centuries afterward, Romans referred to the first day of each month as Kalendae or Kalends from the Latin word calare to announce solemnly, to call out. The word calendar was derived from this custom. The day of Kalends itself began a new month. It was dedicated to Juno, a principal goddess of the Roman Pantheon.
Unnamed days in the early Roman month were assigned a number by counting down following the day of each named phase, day by day, ending with the next of those three phases. Each succeeding day was one number lower than that of the day before. Similar to the modern count-down when coordination of a group of people is required for a complicated activity such as launching a rocket.
Latin for "the evening before" is " Pridie ," a word that was used to refer to the day before each of these named phases. So Pridie was always the day that would otherwise have been numbered two. The count-down was inclusive; the day from which they started as well as that of the moon phase to which they were counting down, day one, were both included. Nones Latin nonus or ninth was originally the day when the moon reached its first quarter phase.
When the pontifex initially saw the lunar crescent he noted its width and, using empirical knowledge, calculated the number of days that were expected to elapse between then and the first quarter moon. He then specified that number after he announced the new crescent.
If he called out the number six, the day following Kalends would be referred to as the sixth day before Nones. In any given year, the second day of Martius might well have been designated as the sixth of the Nones of March: " ante diem VI Non.
The difference between these two dates, eight days, was always the length of the Ides section. Use of the word "Nones" nine was intended to express the inclusive number of elapsed days between first quarter and full moons. Actually, the time between moon phases now averages about 7. Eight-day separations of first quarter and full moons now usually come grouped in consecutive lunations. They then give way to mostly seven-day periods.
Six of the first seven lunations of , for instance, had their first quarter and full moon phases eight days apart inclusive nine-day spans.
Also, July 1 of had a first-quarter moon followed by a new moon on July 9, a nine-day period. Ides, dedicated to Jupiter, was originally the time of the full moon. Because a full moon comes halfway thru each lunation, its day was called Idus in Latin from an Etruscan word meaning "divide.
After Ides, the next new moon was expected to appear in from 15 to 17 days. Variations in the length of time before another new moon can be sighted is due to constantly changing positions of moon and Earth relative to the sun. Romans separated their months from the lunar cycle in the fifth century B. Month lengths then became fixed. It was designated as the 13th day in all other months.
As a result, from then on the Kalends section had from 16 to 19 days, the Nones section had either four or six days and the Ides section, as before, always had eight days. The first day of each new year was represented by the letter "A.
The early Roman calendar originated as a local calendar in the city of Rome, supposedly drawn up by Romulus some seven or eight centuries before the Christian Era. The year began in March and consisted of 10 months, six of 30 days and four of 31 days, making a total of days: it ended in December, to be followed by what seems to have been an uncounted winter gap. Numa Pompilius, according to tradition the second king of Rome ?
To obtain sufficient days for his new months, he is then said to have deducted one day from the day months, thus having 56 days to divide between January and February. But since the Romans had, or had developed, a superstitious dread of even numbers, January was given an extra day; February was still left with an even number of days, but as that month was given over to the infernal gods, this was considered appropriate.
The system allowed the year of 12 months to have days, an uneven number. The so-called Roman republican calendar was supposedly introduced by the Etruscan Tarquinius Priscus B. The Roman republican calendar was a dating system that evolved in Rome prior to the Christian era. According to legend, Romulus, the founder of Rome, instituted the calendar in about B. This dating system, however, was probably a product of evolution from the Greek lunar calendar, which in turn was derived from the Babylonian.
The original Roman calendar appears to have consisted only of 10 months and of a year of days. The Roman ruler Numa Pompilius is credited with adding January at the beginning and February at the end of the calendar to create the month year. In B. By the 1st century B. The occasional intercalation of an extra month of 27 or 28 days, called Mercedonius, kept the calendar in step with the seasons. The confusion was compounded by political maneuvers.
