The Day Function in Excel: All You Need to Know

Excel is one of the most powerful and versatile software applications available. It is used by millions of people around the world to create and analyze complex data sets. The built-in formulas, functions, and features make it incredibly easy to work with numbers, text, and other data. One of the most powerful functions available in Excel is the Day function. This function allows users to quickly and easily extract the day of the week from a given date. In this article, we will discuss the basics of the Day function and how to use it to your advantage. We will also explore some of the more advanced features of the Day function and how to use them to get the most out of your Excel data. By the end of this article, you will have a better understanding of how to use the Day function in Excel and how to maximize its potential.

The Excel DAY function is a useful tool for quickly extracting the day of the month from a date. The syntax for the DAY function is =DAY(serial number). The serial number argument is the date you want to extract the day of the month from. The function will return a number between 1-31, representing the day of the month.

For example, if you enter the following formula into an Excel worksheet:

=DAY(DATE(2018,11,12))

The result will be 12, since the 12th is the day of the month for the given date.

The Excel DAY function can also be used in combination with other date functions such as YEAR, MONTH, and WEEKDAY to extract more information from a date. For example, you can use the following formula to extract the day of the week for a given date:

=WEEKDAY(DATE(2018,11,12))

This will return a number from 1-7, representing the day of the week (Monday-Sunday).

The Excel DAY function is especially useful when combined with other functions such as IF and COUNTIF. For example, you can use the following formula to count the number of days in a given month:

=COUNTIF(A2:A31, “>”&DAY(DATE(YEAR(A2),MONTH(A2)+1,1)-1)

This formula will count the number of dates in the range A2:A31 that are less than the last day of the current month (which is calculated using the DAY function).

In summary, the Excel DAY function is a useful tool for quickly extracting the day of the month from a date. It can be used in combination with other date functions to extract more information such as the day of the week or the number of days in a month.

The Day function in Excel is a powerful and versatile tool that can be used to quickly and easily extract the day of the week from a given date.
