how to use workday function in excel

The WORKDAY function in Excel helps you calculate the date that is a specific number of working days away from a given start date. This is super useful for project planning and scheduling. To use it, you input a start date and the number of days to add. The function then skips weekends and optionally, holidays, to give you an end date.

## How to Use the WORKDAY Function in Excel

In the following steps, you will learn how to use the WORKDAY function in Excel to simplify your project timelines and scheduling tasks.

### Step 1: Open Excel and Select a Cell

Open Excel and select the cell where you want the result to appear.

First things first, open up your Excel workbook. Click on a cell where you want the end date to be displayed. It’s important to choose a cell that makes sense in your spreadsheet layout.

### Step 2: Type the Formula

Enter the formula `=WORKDAY(start_date, days, [holidays])` into the selected cell.

Start by typing `=WORKDAY(`. Excel will prompt you with the formula structure. The `start_date` is the date from which you want to start counting, `days` is the number of working days to add, and `[holidays]` is an optional range of dates you want to exclude as holidays.

### Step 3: Input the Start Date

Input your start date within the formula either by clicking a cell or typing a date.

If your start date is in another cell, click that cell. If you’re typing it manually, ensure it’s in quotes like `"01/01/2023"`. This tells Excel where to begin counting.

### Step 4: Enter the Number of Days

Type in the number of working days to add in the formula.

After the start date, type a comma and then the number of days you want to add. This should be a whole number. Excel will then know how many working days to count forward.

### Step 5: Add Holidays (Optional)

Specify any holidays you want to exclude by entering a cell range or specific dates.

If you have holidays to consider, include them in your formula by adding a comma after the days and then highlighting the range of holiday dates in your spreadsheet. If not, you can close the formula with a parenthesis.

### Step 6: Press Enter

Hit the Enter key to execute the formula.

Once you’ve entered all the necessary components of the WORKDAY function, press Enter. Excel will calculate and display the end date in the selected cell.

After completing these steps, Excel will give you a date that skips weekends and any specified holidays. This is your project end date or due date.

## Tips for Using the WORKDAY Function in Excel

• Always double-check your start date format. Incorrect formats can cause errors.
• Use cell references for dates and days for easier adjustments later.
• If your project spans multiple months, consider adding holidays to avoid inaccuracies.
• Use the WORKDAY.INTL function for custom weekend definitions.
• Combine with other functions like NETWORKDAYS for more complex scheduling needs.
