Choosing the right interpretation of a year number is difficult, so much more as one country might use different systems for religious and civil needs. Since about most countries have used 1 January as the first day of the year.
Italy and England, however, did not make 1 January official until around It is sometimes claimed that having the year start on 1 January was part of the Gregorian calendar reform. This is not true. This myth has probably started because in England moved the start of the year to 1 January and also changed to the Gregorian calendar. But in most other countries the two events were not related. Scotland, for example, changed to the Gregorian calendar together with England in , but they moved the start of the year to 1 January in If the year started on, for example, 1 March, two months later than our present year, when was the leap day inserted?
When it comes to determining if a year is a leap year, since AD 8 the Julian calendar has always had 48 months between two leap days. So, in a country using a year starting on 1 March, would have been a leap year, because their February would correspond to February in the January-based reckoning. A lot of languages, including English, use month names based on Latin. Their meaning is listed below.
However, some languages Czech and Polish, for example use quite different names. February Februarius Named after Februa, the purification festival. March Martius Named after the god Mars. April Aprilis Named either after the goddess Aphrodite or the Latin word aperire, to open.
May Maius Probably named after the goddess Maia. June Junius Probably named after the goddess Juno. Prior to that time its name was Quintilis from the word quintus, fifth, because it was the 5th month in the old Roman calendar.
August Augustus Named after emperor Augustus in 8 B. Prior to that time the name was Sextilis from the word sextus, sixth, because it was the 6th month in the old Roman calendar. September September From the word septem, seven, because it was the 7th month in the old Roman calendar. The moon is where the concept of a month comes from. Many cultures used months whose lengths were 29 or 30 days or some alternation to chop up a year into increments.
The main problem with this sort of system is that moon cycles, at When you look at the modern calendar, the months are extremely confusing. One has 28 or 29 days, some have 30 days and the rest have 31 days. According to the "World Book Encyclopedia," here is how we got such a funny calendar:.
This little history explains why we have 12 months, why the months have the number of days they have, why leap day falls at such an odd time and why the months have such funny names. What about weeks? Days, months and years all have a natural basis, but weeks do not. They come straight out of the Bible:. The Romans gave names to the days of the week based on the sun, the moon and the names of the five planets known to the Romans:.
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! If you check your calendar , you'll notice that February only has 28 days unless it's a leap year , September only has 30 days, October only has 31 days, and November only has 30 days.
What's the deal with that? To solve this mystery, we must dig deep into the history of our modern calendar , which is known as the Gregorian calendar. The Gregorian calendar was a modification of the Julian calendar , which itself was a modification of the ancient Roman calendar. The ancient Romans, like ancient civilizations before them, based their concept of the month on the Moon. Unfortunately, the lunar cycle is approximately As a result, the earliest ancient Roman calendars had months that were either 29 or 30 days.
To make things even more confusing, the ancient Romans borrowed from the ancient Greeks to develop the idea of a month calendar that left approximately 60 days unaccounted for.
For example, the ancient Romans started using a month calendar in B. The names Quintilis through December derived from the Latin words for five through ten. To account for the remaining 60 or so days, Januarius was added to the beginning of the year and Februarius to the end of the year during Numa's reign around B.
The calendar stayed in that order until B. Julius Caesar modified the Roman calendar in 46 B. Quintilis was later renamed Julius in his honor. Likewise, Sextilis later became Augustus to honor Augustus Caesar. Augustus was also given an extra day taken away from Februarius , so that Augustus and Julius would have an equal number of days. So the next time you're curious about why a particular month has the number of days that it does, you can thank the Moon and the ancient Romans!
In tomorrow's Wonder of the Day, we say goodbye to a year gone by and welcome the promises of a new year ahead! Are you already counting down the days until next month? Be sure to check out the following activities with a friend or family member:. I learned months are as long as it takes for the full moon to go around back to a full moon and it does this 12 times a year which is why there are 12 months but since Sure thing!
My system is simple, really. It's based loosely on how the Romans originally had it. Starting the year with March, and ending it with February, each other month has either 31 days or 30 days. The exception is of course February, which only has March is 31, April is 30, May is 31, etc.
Yet, as simple as this method is, I fear it's just as likely to change as the electoral college is Because if it matches the lunar cycle perfectly, Spring would keep moving. As would all other seasons. Hi, Wonder Friend! Sometimes there isn't a clear cut answer to our questions, which can be frustrating.
But we hope that you'll continue researching to find out more information! Probably because in acient history they got tired of being in the same month instead of being in the same month for 29 days.
Thanks for sharing your thoughts, makiya! We hope this Wonder helped you learn more about how the months got their number of days! Hi, Sydney! In the Wonder text above, we briefly touched on why February has fewer days than the rest of the months. However, a longer explanation can be found at The Galileo Project website. We hope that helps! Thanks for joining the discussion, Matthew! We encourage you to check out The Galileo Project website as well!
