5 Excel Formulas To Convert Dates Into Days Of The Week

Excel is an incredibly powerful tool, and knowing how to manipulate dates to extract specific information can be a game changer for data management. One of the common tasks users encounter is converting dates into the corresponding days of the week. Fortunately, Excel makes this process straightforward with a variety of formulas that can help you do just that. Here, we’ll explore five effective Excel formulas that will help you convert dates into the days of the week. 💡

Understanding the Basics of Date Formatting

Before diving into the formulas, it’s essential to grasp how Excel handles dates. Excel treats dates as serial numbers, starting from January 1, 1900. For instance, January 1, 1900, is represented as 1, while January 2, 1900, is 2, and so on. This means that when you input a date into Excel, it can perform mathematical calculations based on these serial numbers.

Formula 1: Using the TEXT Function

The simplest way to convert a date into a day of the week is by using the TEXT function. Here’s how:

=TEXT(A1, "dddd")

• A1 is the cell containing the date you want to convert.
• "dddd" returns the full name of the day (e.g., "Monday").

If you prefer the abbreviated form (e.g., "Mon"), you can use:

=TEXT(A1, "ddd")

Example Scenario: If cell A1 has the date 01/01/2023, using the above formula will return "Sunday".

Formula 2: Using the WEEKDAY Function

The WEEKDAY function provides a number representing the day of the week, which can be further manipulated to display the name of the day.

=WEEKDAY(A1, 1)

• The first argument is the date (A1).
• The second argument is the return type; "1" means Sunday = 1, Monday = 2, and so forth.

To convert this number into a text day, you can combine it with the CHOOSE function:

=CHOOSE(WEEKDAY(A1, 1), "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday")

This will give you the full name of the day based on the numerical output of the WEEKDAY function.

Important Note: Adjust the return type in the WEEKDAY function if you prefer a different starting day of the week (e.g., 2 for Monday).

Formula 3: Using the TEXT and DATEVALUE Functions Together

If you're dealing with dates in text format, you might want to convert them first before extracting the day. Here’s a combination of TEXT and DATEVALUE:

=TEXT(DATEVALUE(A1), "dddd")

• This first converts the date in text format to a valid Excel date before formatting it.

This is particularly useful when dealing with imported data that might not be recognized as dates.

Formula 4: Utilizing the EDATE Function

If you need to calculate the day of the week for dates offset by a certain number of months, the EDATE function comes in handy. You can combine this with the TEXT function:

=TEXT(EDATE(A1, 1), "dddd")

• This will calculate the date one month later than the date in A1, and return the day of the week for that new date.

Formula 5: Using the NETWORKDAYS Function for Weekday Calculation

If you're interested in calculating working days and their corresponding weekdays, the NETWORKDAYS function can help:

=TEXT(NETWORKDAYS(A1, A1), "dddd")

• This formula counts the number of working days between two dates. Since we're only using the same date (A1), it effectively gives us the weekday, ensuring we only consider weekdays.

Common Mistakes to Avoid

• Date Format Issues: Ensure your dates are correctly formatted as Excel dates. Otherwise, formulas will not work as expected.
• Using Incorrect Cell References: Double-check that your formulas reference the correct cells containing the dates.
• Formula Structure: Maintaining proper syntax and structure in your formulas will prevent errors. A small typo can lead to frustrating debugging sessions!

Troubleshooting Tips

• If your formulas return an error, verify if the date in the referenced cell is valid.
• For the TEXT function, remember to apply the correct format strings ("dddd" for full names and "ddd" for abbreviations).
• Adjust your regional settings if date formats appear incorrect, as this can affect how Excel interprets your input.
