## Why Are There 7 Months with 31 Days?

There are seven months out of the year with 31 days. This is because the lunar cycle is 29.5 days long, and it takes 30.44 days to orbit around the sun.

When you have a 31-day month, it’s called a “long month.”

The extra day in a long month helps to keep the calendar year synchronized with the solar year. If there were no long months, then eventually the seasons would get out of whack.

For example, if February always had 28 days, then every 4 years there would be an extra day tacked on at the end of the month. Over time, this would cause spring to arrive earlier and earlier.

Having long months keeps everything nice and orderly, which is why we have 31 days in seven different months out of the year. Thanks, long months!

## What Seasons Fall in 31-Day Months?

Most of the months with 31 days are in the autumn and winter seasons. October, December, and January are typically cold months with shorter days.

March also has 31 days, and although it is the beginning of spring, in many places it is still quite cold.

So, if you’re looking for a month with 30 days to celebrate a holiday, you’re most likely to find one in September, April, June, or November.

But if you want to enjoy the warmer weather, you’ll have to wait until March, May, July, or August.

## What Months Have 30 Days?

There are twelve months in a year, and each month has either 28, 30, or 31 days. Out of the twelve months, only four have 30 days.

Those months are September, April, June, and November.

All the rest have 31 days except for February which has 28 days (29 in leap years).

## Why Do Some Months Have 30 Days?

The reason why some months have 30 days has to do with the moon and its phases.

A lunar month is a time it takes for the moon to go from a new moon (when it is black) to a full moon (when it is bright) and back to a new moon again.

This cycle takes about 29.5 days on average. That’s why February is the only month that can have 28 or 29 days.

The other 30-day months are September (Latin for “seven”), April (Latin for “to open”), June (named after the Roman goddess Juno), and November (Latin for “nine”).

## What Holidays Do 30-Day Months Have?

Since 30-day months have one extra day, they are good months for holidays.

In the United States, September has Labor Day, October has Halloween, and November has Thanksgiving.

In other countries, May 1 is a holiday in many places. It is called International Workers’ Day or May Day.

June 2 is also a popular day for holidays. It is called Eid al-Fitr and marks the end of Ramadan, the Islamic month of fasting.

## Do All Months Have 30 Days?

No, not all months have 30 days. As we mentioned before, there are twelve months in a year, and each month has either 28, 30, or 31 days.

Out of the twelve months, only four have 30 days. Those months are September, April, June, and November.

All the rest have 31 days except for February which has 28 days (29 in leap years).

## Why Do February Have 28 Days?

February has 28 days because it is the shortest month. It is also the only month that can have 29 days in a leap year.

A leap year happens every four years, and February gets an extra day because the Earth’s orbit around the sun takes 365.24 days—a bit more than 365 days.

So, every four years, we add an extra day (February 29) to keep the calendar in sync with the Earth’s orbit.

## What is a Leap Year?

Leap years occur every 4 years, and February gains an extra day, or 29 days total. Non-leap years are any other year that isn’t divisible by 4. So the next leap year is 2020, followed by 2024, 2028, and so on.

If you’re born on a leap day, February 29th, then you technically only have a birthday every 4 years! Leap years are special because they help keep our calendar aligned with the Earth’s revolutions around the sun.

Over time, without leap years, our calendar would become misaligned with the seasons.
