Excel Formula To Convert Date To Day Of Week Easily

Excel formulas can be incredibly powerful tools for manipulating and analyzing data. One common task that users often face is converting a date to the corresponding day of the week. This can be particularly useful for scheduling, calendar-based analyses, and more. Excel provides several formulas to achieve this conversion with ease.

Understanding the Need to Convert Dates

Converting dates to days of the week can be essential for various tasks, including creating weekly schedules, analyzing sales trends by day of the week, or simply organizing events. Excel's formulas make this process straightforward, allowing you to focus on the insights and actions derived from the data rather than the data manipulation itself.

The WEEKDAY Function: A Simple Approach

One of the most straightforward ways to convert a date to the day of the week in Excel is by using the WEEKDAY function. This function returns a number from 1 (Sunday) to 7 (Saturday) representing the day of the week for a given date.

• Syntax: WEEKDAY(serial_number, [return_type])
• serial_number: The date for which you want to find the day of the week.
• [return_type]: An optional argument that specifies the type of return value. By default (or if 1 is used), Sunday is returned as 1 and Saturday as 7. If 2 is used, Monday is returned as 1 and Sunday as 7.

Example:

Suppose you have a date in cell A1, and you want to find out the day of the week for this date using the default return type.

=WEEKDAY(A1)

The TEXT Function: A Customizable Approach

For more customized results, such as displaying the full day name (e.g., "Monday") instead of a number, you can use the TEXT function in combination with the WEEKDAY function.

• Syntax: TEXT(date, format_text)
• date: The date you want to convert.
• format_text: The format of the result. You can use "dddd" for the full weekday name.

However, to directly convert to the day of the week using TEXT, you would still need to use WEEKDAY within the formula to first determine the day of the week, then use TEXT to format the output, which isn't as straightforward.

The CHOOSE Function: A More Versatile Method

Another approach to converting a date to the day of the week involves using the CHOOSE function in combination with WEEKDAY. This method allows for more flexibility in the output format.

• Syntax: CHOOSE(index_num, value1, [value2],...)
• index_num: The position of the value to return. Use the WEEKDAY function here.
• value1, [value2],...: The list of values to choose from.

Example:

If you want to display the full day names based on the date in A1, you can use the following formula:

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

This formula uses WEEKDAY(A1) to determine the day of the week (as a number) and then uses CHOOSE to select the corresponding day name from the list.

Additional Tips and Considerations

• Locale and Language: The display of day names can be affected by your Excel settings, including your locale and language. Ensure your settings match the language you're using in your formulas.
• Combining Functions: Often, the most powerful Excel formulas involve combining multiple functions. Experiment with different combinations to achieve the desired output.
