Hello! As an expert in various fields, including general knowledge, I'm here to provide you with accurate and helpful information. Let's dive into the question about the months with less than 31 days.
In the Gregorian calendar, which is the most widely used calendar system today, there are 12 months. These months are divided into three categories based on the number of days they contain:

1. Months with 31 days: These are considered "long" months and include January, March, May, July, August, October, and December. Each of these months has exactly 31 days.

2. Months with 30 days: These are considered "short" months and include April, June, September, and November. Each of these months has exactly 30 days.

3. February: This is a unique month as it has either 28 or 29 days, depending on whether it is a common year or a leap year. In a common year, February has 28 days, while in a leap year, it has 29 days.

Now, focusing on the question at hand, the months with less than 31 days are all months except for the seven "long" months mentioned earlier. Therefore, the months with less than 31 days are:

- April
- June
- September
- November

It's important to note that February is also less than 31 days, but since it varies between 28 and 29 days, it's not typically categorized with the "short" months that consistently have 30 days.

To further clarify, let's discuss the "knuckle method" you mentioned. This is a mnemonic technique used to remember the number of days in each month. Here's how it works:

1. Fold your hand into a fist, and you'll see that you have four knuckles on each side (excluding the thumb).
2. The knuckles represent the "long" months with 31 days, while the spaces between the knuckles represent the "short" months with 30 days.
3. The two knuckles where your hands meet represent July and August, both of which are "long" months with 31 days.

Using this method, you can easily recall the number of days in each month by looking at your hand. The knuckle method is a fun and effective way to remember the calendar, especially for children or anyone learning about the months and their respective day counts.

In conclusion, the months with less than 31 days are April, June, September, and November, with February also having less than 31 days but varying between 28 and 29 days. The knuckle method is a helpful mnemonic tool for remembering the day counts of each month.

April, June and November. Or you can use the "knuckle method": A knuckle is "31 days", and in between each knuckle it isn't. And where you hands meet, the two knuckles are "July, August", which both have 31 days.read more >>
