Did you know the names of the months are older than the calendar?
There are only 12 months in a year, with the start of every brand new year filled with resolutions, goals and promises. From forming good habits to learning new and exciting things, everyone is busy trying to make positive changes.
But….what do you think is the first thing we all change without fail at the start of a new year, with or without a resolution? It’s the calendar itself!
However, do you know that the names of the months are much older than the modern day calendar?! Have you ever wondered where the unique names of all months come from?
Some of the names sound like they might be English words but most of them sound exotic, don’t they? Well, wonder no more! In today’s story, we take you time-hopping through the calendar to explore the fascinating stories behind the names of each month in the year (Psst! As with a lot of things, the people responsible for this are the ancient Romans!)
The Gregorian Calendar – The calendar followed throughout the world:
The Gregorian calendar has a history older than itself. You’ll read more on that later in this post. The calendar that we follow internationally and the one that you see on your desktops and cell phones are all Gregorian calendars. This calendar had replaced the old Julian calendar in 1582 and over centuries it was used across cultures and countries all across the world. There are two main types of calendars, one is lunar based while the other is solar based. The Greek calendar was a solar based calendar.
Quick Fact Did you know that before the modern calendar took shape, the Roman Calendar was being followed which had just 10 months. |
Facts about the Gregorian calendar or the modern calendar:
- The modern calendar is a Solar calendar.
- It has a total of 12 months in a calendar year.
- Each month has a total of 28 days, 29 days, 31 days or 30 days depending on the month and year of the calendar.
- According to this calendar there are 365 days in a year.
- Every four years we have something called a leap year when an extra day is added to the month of February which usually has 28 days. This makes February in the leap year have 29 days.
- In a leap year there are 366 days in a year with 29 days in February instead of 28 days.
The Names of Months With Number of Days |
|
January
31 days The first month of the year, January gets its name from the Roman god Janus. A mythical deity with two faces, Janus was said to be able to look at the past and the future at the same time. Also symbolising gates and doors, Janus is thought to be the symbol of entering a new era or time. |

February
28/29 days February comes from the Latin word “’februare” which means “to purify”. Some believe that February, being the last month added to the calendar, was meant to “purify” it and make it an accurate record of time. Read Also: Why Is February So Odd This Year? |

March
31 days The pleasant month of March is actually named after the violent Roman god of war, Mars. Romans believed that the good weather in March was a great time to resume their battles with enemy kingdoms and hence named it after their god of war. |

April
30 days The etymology for the month of April is by far the most debated of all the calendar months. However, one interesting theory links the naming of April to springtime. Coinciding with the time when flowers begin to bloom, some scholars believe that April comes from the Latin word ‘aperire’ which means ‘to open,’ as flowers do in spring! |

May
31 days The origin of the month of May is relatively more straightforward. To celebrate the earth in all its glory as it begins to bloom and grow in the thick of spring, the month of May gets its name from Maia, the Roman goddess of the Earth. |

June
30 days In ancient Rome, the start of summer was a time to get married! A part of the Northern hemisphere, the days start getting longer around the middle of the year in Rome and a lot of celebrations, including marriages, was planned around this time. To commemorate this, Juno, the Roman goddess of marriages lends her name to the month of June.

July
31 days Arguably one of the most famous personalities from ancient Rome, the month of July is named after Julius Caesar. Following his assassination in 44 B.C., the month was renamed ‘July’ to honour Caeser, who was born in the said month. This was also the first month that was named after a real person and not a mythological deity.

August
31 days The month of August gets its name from the Roman Emperor Augustus Caesar, Julius Caesar’s nephew. Considered to be one of the greatest emperors of Rome, Augustus was immortalised with the naming of the month. The name ‘Augustus’ also means ‘respected’ or ‘impressive’. In English, the word ‘august’ is used to denote this too! For example, ‘The professor has an august reputation for his work!’

September, October, November & December
30, 31, 30 & 31 days September, October, November and December, the last four months of the year seem to rhyme. No, that was not a coincidence. Originally, the last four months of the year were the seventh, eighth, ninth and tenth months respectively in the old 10-month-long Roman calendar. Hence, their names also reflect the same, being named after the corresponding Roman numerals. However, once January and February were added to the calendar to make it more accurate, these last four months got pushed from their spots! Their names, however, stayed the same.

Easy way to remember the days in a month: (Knuckle mnemonic)
Some of you may already know this little trick. It is a very effective way to find out the number of months in a year. It is sometimes called the Knuckle mnemonic as we use the. There are two methods in Knuckle mnemonics.
In both these methods you will assign each knuckle with a value of 31 days and each depression between the knuckle with 30 days, 28 days or 29 days.
- Single Hand:
In the single handed method you start from the first knuckle (little finger knuckle) as January and the adjacent depression as February and the next knuckle as March until the last Knuckle as July. Remember to say the months while doing this.
Now repeat this again by coming back to the little finger knuckle (Now August) and then continue until you finish all the months.
There is another variation In this method where you could also reverse your direction of counting once you reach the last knuckle instead of starting from the little finger knuckle after reaching July.
- Double Hand:
In this second method you can use both your hands. You will need to make a fist and place your hands next to each other with the knuckles of your index fingers touching each other.
Just like in the previous method you can start from the small finger knuckle saying January and then when you reach the last knuckle of your hand jump to the next knuckle (index finger knuckle) on the second hand and then continue to complete the months.
What is a leap year?
In the Gregorian Calendar one year is not equal to 365 days. There is a quarter of a day in each year that gets carried over. That is why after completing four years you end up with four quarters of a day which is the same as a whole day. This day is what gets added to February thereby giving 29 days in that month when it is done. That year when February has 29 days instead of the usual 28 days is called a leap year.
How to calculate the next leap year?
For most of the years once you add 4 years to a leap year you get the next leap year but that does not hold true when you consider long spans.
Here is a simple way to calculate leap years:
- If the year under consideration is evenly divisible by 4 then,
- Check If the year is evenly divisible by 100. If it is still divisible then check
- If the year is evenly divisible by 400.
If your answer is a Yes after the above three checks then the year under consideration is a leap year.
But if the year is divisible by four and not divisible by 100 you still have a leap year.
But if the year is divisible by four, divisible by 100 and not divisible by 400 it is not a leap year.
Here is a list of leap years for years from 2000 to 2100:
Leap Years from 2000 to 2100 |
||
2000 | 2004 | 2008 |
2012 | 2016 | 2020 |
2024 | 2028 | 2032 |
2036 | 2040 | 2044 |
2048 | 2052 | 2056 |
2060 | 2064 | 2068 |
2072 | 2076 | 2080 |
2084 | 2088 | 2092 |
2096 | – | – |
In the above table, notice how 2100 failed to appear as a leap year. This is because despite the year being divisible by both 4 and 100 it was not divisible by 400 and hence is not a leap year.
So there you have it! Once again we see that history lives on with us even today. The Roman emperors who made the first calendars may be long gone. But the legacy of their culture still lives with us today in the form of the modern calendar! Want to know more about culture, history and geography? Check out the BYJU’S social science videos here!
