The Simple Answer Is Cus Then Each Year Would Not Have Enough Days then. For example if each month had 30 days with 12 months that would be 360 days but there are 365 days in a year (366 leap year). So the biggest reason why there are different days in months are cus there won’t be enough days in a year.

Why are the number of days different in each month?
The ancient Romans, like ancient civilizations before them, based their concept of the month on the Moon.Julius Caesar modified the Roman calendar in 46 B.C. to make each month have either 30 or 31 days, with the exception of Februarius, which had 29 days and gained an extra day every fourth year.
Why do some months have more days than others?
The reason that some months are longer than others is that to make their months longer, they took months from other days. So July and August are both 31 days, while others are shorter.
Why are there 7 months with 31 days?
The months of January and February were added to the calendar and the original fifth and sixth months were renamed July and August in honour of Julius Caesar and his successor Augustus. These months were both given 31 days to reflect their importance, having been named after Roman leaders.
What determines how many days a month has?
29.53 days
A month is a unit of time, used with calendars, that is approximately as long as a natural orbital period of the Moon; the words month and Moon are cognates. The traditional concept arose with the cycle of Moon phases; such lunar months (“lunations”) are synodic months and last approximately 29.53 days.
Why does February have less days?
This is because of simple mathematical fact: the sum of any even amount (12 months) of odd numbers will always equal an even number—and he wanted the total to be odd. So Numa chose February, a month that would be host to Roman rituals honoring the dead, as the unlucky month to consist of 28 days.
Why is a month not 27 days?
Anomalistic month
The Moon’s orbit approximates an ellipse rather than a circle. However, the orientation (as well as the shape) of this orbit is not fixed.This longer period is called the anomalistic month and has an average length of 27.554551 days (27 d 13 h 18 min 33.2 s).
Why do some months have more than 28 days?
Because Romans believed even numbers to be unlucky, each month had an odd number of days, which alternated between 29 and 31. But, in order to reach 355 days, one month had to be an even number. February was chosen to be the unlucky month with 28 days.
Which month has a different number of days from all the other months?
All months have 30 or 31 days, except for February which has 28 days (29 in a leap year). Every fourth year, the month of February has 29 days instead of 28. This year is called a “leap year” and the 29th day of February is a “leap day”.
Are there twelve months?
The 12 Months of the Year. A year is divided into 12 months in the modern-day Gregorian calendar. The months are either 28, 29, 30, or 31 days long.During leap years, which occur nearly every 4 years, we add an extra (intercalary) day, Leap Day, on 29 February, making leap years 366 days long.
Why is October not the 8th month?
Why Is October Not the Eighth Month? The meaning of October comes from the Latin word Octo meaning eight. The old Roman calendar started in March, so October was the eighth month. When the Roman senate changed the calendar in 153 BCE, the new year started in January, and October became the tenth month.
Who invented the 7 day week?
For centuries the Romans used a period of eight days in civil practice, but in 321 CE Emperor Constantine established the seven-day week in the Roman calendar and designated Sunday as the first day of the week.
How were all the months named?
Tradition had it that Romulus named the first month, Martius, after his own father, Mars, the god of war.Thereafter, however, the months were simply called the fifth month (Quintilis), sixth month (Sixtilis) and so on, all the way through to the tenth month, December.
How were months determined?
As a calendrical period, the month is derived from the lunation—i.e., the time elapsing between successive new moons (or other phases of the moon). A total of 12 lunations amounts to 354 days and is, roughly, a year. A period of 12 lunations was therefore used by some primitive peoples to make their calendrical year.
How many months were there originally?

Why does a year have 365 days?
The Earth’s orbit around the Sun takes 365.24 days. A ‘day’ is defined as the Earth spinning once on its axis.The Earth takes approximately 365.25 days to go around the Sun, yet our calendar year is 365 days. To fix this, we put on extra days in some years, called leap years.
Does a leap year have 365 days?
A year, occurring once every four years, which has 366 days including 29 February as an integral day is called a Leap year. 2021 is not a leap year and has 365 days like a common year. It takes approximately 365.25 days for Earth to orbit around the Sun.
Does month come from Moon?
A month is a unit of time that corresponds to the phases of the moon — which is the reason the word month, which comes from the Proto-Germanic menoth, is closely related to the word moon, whose root is menon.
Why was February chosen for leap year?
February 29 is a date that usually occurs every four years, and is called the leap day. This day is added to the calendar in leap years as a corrective measure because the Earth does not orbit the Sun in precisely 365 days. The Gregorian calendar is a modification of the Julian calendar first used by the Romans.
Does the moon rotate?
The moon does rotate on its axis. One rotation takes nearly as much time as one revolution around Earth.Over time it has slowed down because of the effect of Earth’s gravity. Astronomers call this a “tidally locked” state because it will now remain at this speed.
