How to Use the DAY Excel Function
For good reason, Excel is one of the world’s most popular data analysis tools. With its powerful functions and intuitive interface, Excel makes it easy to analyze large amounts of data and create professional-looking reports.

=DAY(serial_number)
Where serial_number is a date value that you want to extract the day from.
For example, if you have a date in cell A1 and you want to extract the day from it, you can use the following formula:
=DAY(A1)
This will return the day of the month as a number.
Why the DAY Function Matters
The DAY function is useful and can help you analyze your data differently. Here are just a few examples of how you can use the DAY function in Excel:
- Calculating the number of days between two dates: By using the DAY function to extract the day of the month from two dates, you can easily calculate the number of days between them.
- Filtering data by day of the month: By using the DAY function in combination with other functions like FILTER or SORT, you can easily filter your data only to show entries from a specific day of the month.
- Analyzing trends over time: Using the DAY function and other functions like AVERAGE, you can easily analyze trends over time to see if certain days of the month are more profitable or productive than others.
Benefits of Using the DAY Excel Function
The DAY Excel function can be incredibly useful when working with dates in Excel. Also, here are just a few of the benefits it provides:
- Simplifies data analysis: By extracting the day from a date, you can more easily analyze data based on specific days of the month. This can be especially useful for tracking sales, expenses, or other financial data.
- Saves time: Instead of manually extracting the day from a date, the DAY function allows you to do it quickly and easily.
- Reduces errors: Because the DAY function is built into Excel, you can be sure that it will return accurate results every time.

DAY Excel Function Example
Let’s say you’re tracking sales data for your business and want to analyze sales by day of the month. You have a table with the following data:
| Date | Sales |
|---|---|
| 2023-01-01 | $100 |
| 2023-01-02 | $200 |
| 2023-01-03 | $300 |
| … | … |
To extract the day from the date, you can use the following formula in a new column:
=DAY(A2)
This will return the day of the month as a number. Also you can then use this data to perform various calculations and analyses based on specific days of the month.
The Basic Syntax of the DAY Function
The DAY function is a built-in function in Excel that allows you to extract the day of the month from a date. The basic syntax of the DAY function is as follows:
=DAY(serial_number)
The “serial_number” argument in this function is the date you want to extract the day from. Also, this argument can be entered in several formats, including as a date in quotation marks, as a reference to a cell containing a date, or as a formula that returns a date.
For example, if you want to extract the day from the date “January 15, 2023”, you would enter the following formula:
=DAY("1/15/2023")
This formula would return the value “15”, which is the day of the month.
Advanced Applications of the DAY Function
While the basic syntax of the DAY function is simple, this function can be used in various ways to make your Excel spreadsheets more effective. Here are just a few examples of the advanced applications of the DAY function:
Calculating the Number of Days Between Two Dates
One common use of the DAY function is calculating the number of days between two dates. Furthermore, to do this, you can subtract the earlier date from the later date, and then use the DAY function to extract the day of the month from the result.
For example, if you have two dates in cells A1 and B1, you can calculate the number of days between these dates with the following formula:
=DAY(B1-A1)
This formula will return the number of days between the two dates, including the fractional part of the result. If you want to round the result to the nearest whole number, you can use the ROUND function, like this:
=ROUND(DAY(B1-A1),0)
This formula will return the number of days between the two dates, rounded to the nearest whole number.
Calculating the Number of Days Until a Future Date
Another common use of the DAY function is to calculate the number of days until a future date. To do this, you can subtract the current date from the future date. Also, then use the DAY function to extract the day of the month from the result.
For example, if you want to calculate the number of days until December 31, 2023, you can use the following formula:
=DAY("12/31/2023")-DAY(TODAY())
This formula subtracts the current day of the month from the day of the month for December 31, 2023, giving you the number of days until that date.
Filtering Data by Day
The DAY function can also filter data in Excel by the day of the month. For example, if you have a list of transactions that includes the date of each transaction, you can use the DAY function to filter the list to show only transactions that occurred on a specific day of the month.
To do this, you can use the FILTER function in Excel and the DAY function. For example, if you want to filter a list of transactions to show only transactions that occurred on the 15th day of the month, you can use the following formula:
=FILTER(transactions, DAY(date)=15)
This formula filters the “transactions” range to show only rows where the day of the month in the “date” column is equal to 15.
Calculating the Day of the Week
In addition to calculating the day of the month, the DAY function can also be used to calculate the day of the week. Also, you can use the WEEKDAY function in Excel and the DAY function to do this.
For example, if you have a date in cell A1 and you want to calculate the day of the week for that date, you can use the following formula:
=WEEKDAY(A1)
This formula returns a number between 1 and 7, where 1 represents Sunday, 2 represents Monday, and so on.
