# Weekday Formula Excel: An Essential Tool For Your Spreadsheet

## Introduction

Excel is an essential tool for businesses and individuals to organize and analyze data. However, working with dates in Excel can be challenging, especially when you need to calculate weekdays accurately. The good news is that Excel has a formula that can help you with this task: the “weekday formula.” In this article, we’ll explore what the weekday formula is and how to use it effectively.

## What Is the Weekday Formula?

The weekday formula is an Excel function that helps you determine the day of the week for a given date. It returns a number between 1 and 7, representing the day of the week, with 1 being Sunday and 7 being Saturday. The formula takes three arguments: the date, the type of return value, and the optional argument to specify the starting day of the week.

### How to Use the Weekday Formula

To use the weekday formula, you need to start by selecting the cell where you want to display the result. Then, type “=WEEKDAY(” followed by the date you want to evaluate. Next, you need to specify the type of return value you want. There are two options: 1 for returning the day of the week as a number between 1 and 7 or 2 for returning the day of the week as an abbreviation. Finally, you can specify the starting day of the week by adding a third argument, which is optional.

## Sample Weekday Formulas

Here are three examples of how to use the weekday formula in Excel:

**1. Display the day of the week as a number:**

=WEEKDAY(“2023-09-15”,1)

Result: 5 (which means Thursday)

**2. Display the day of the week as an abbreviation:**

=WEEKDAY(“2023-09-15”,2)

Result: Thu

**3. Display the day of the week using a custom starting day:**

=WEEKDAY(“2023-09-15”,1,2)

Result: 4 (which means Wednesday, as we specified the starting day of the week as Monday)

## Tips for Using the Weekday Formula in Excel

Using the weekday formula in Excel can be tricky, especially if you’re not familiar with the syntax. Here are some tips to help you use it effectively:

**1. Use the DATE function to input dates:**

Instead of typing dates manually, use the DATE function to input them. This function takes three arguments: the year, month, and day. For example, to input September 15, 2023, you would use the formula “=DATE(2023,9,15)”.

**2. Use conditional formatting to highlight weekdays:**

Conditional formatting is a great way to highlight weekdays in your spreadsheet. You can use the WEEKDAY formula to determine if a cell contains a weekday and then apply a formatting rule to highlight it.

**3. Be aware of the starting day of the week:**

The starting day of the week can vary depending on your location and culture. In Excel, the default starting day is Sunday, but you can change it to Monday or any other day by using the third argument of the weekday formula.
