Are you having trouble adding days to a date in Excel? This step-by-step guide will show you how to do it quickly and easily. You can use this to automate your date tracking and make your workflow smoother. Let’s get started!

## How to Add Days to a Date in Excel: A Comprehensive Guide

Excel users, fear not! We’ve got you covered when it comes to calculating dates. Adding days to a date can be tricky, but this guide will show you how it’s done. First, we’ll learn how the Excel date system works. No matter if you’re a pro or a beginner, this guide will help you master date calculations.

Let’s get started!

### Mastering the Excel Date System for Accurate Calculations

Understanding how Excel’s two date systems interact is key for accurate calculations. Serial numbers are days since January 1, 1900, and dates are traditional calendar dates. To master the date system: Select cells, type desired date (in a predefined format), verify that it appears as a recognizable date, and use functions/formulas to manipulate it. Different countries use different conventions for displaying dates, so double-check when exchanging data. Now we’ll explore adding days to a date in Excel for easier manipulation.

## Adding Days to a Date

Do you use Excel a lot? Adding days to a date can be a routine task, but sometimes it’s tricky. Let’s explore 3 ways of doing this in Excel.

1. The Basic Method – using the DATE function.
2. The Advanced Method – using the EDATE function.
3. The Business Days Method – using the WORKDAY function. We’ll also learn how to skip weekends and holidays.

Let’s start!

### Basic Method: Using the DATE Function

Need to add days to a date in Excel? The DATE Function is the basic way! Here’s a 4-step guide to get you started.

1. Select a cell for the result.
2. Type “=” in the formula bar, then start typing “DATE”. Click/tap it in the suggestions.
3. Inside the parentheses, enter 3 comma-separated arguments: year, month and day.
4. Press “Enter” or click/tap outside the formula bar to evaluate your formula.

That’s it! You’ve now got a new date value in the selected cell. Worried about which method is best? Don’t be – we’re here to help. Avoid wasting time by using Excel’s capabilities!

Ready for more? Try EDATE Function – an even faster approach that knows how many months away your target date is!

### Advanced Method: Using the EDATE Function

The EDATE Function is a useful way to add days to a date in Excel. Here’s how to use it in 5 steps:

1. Select the cell where you want to enter the formula.
2. Type =EDATE( and then select the cell with the starting date.
3. Put a comma (,) after the starting date cell reference and enter the number of months to add. Use negative numbers to subtract months.
4. Close the bracket and press Enter. The result will be displayed in the selected cell.
5. To copy this formula to other cells, click and drag from the bottom right corner of the cell.

Limitations: This function only works with months, not individual days or weeks. To add or subtract months and days from a date, combine EDATE with other Excel functions like DAY, MONTH, and YEAR.

Business Days Method: The WORKDAY Function is another way of adding days to a date in Excel. It can be useful for project management or finance data.

### Business Days Method: Using the WORKDAY Function

The Business Days Method is super useful! Excel’s WORKDAY Function makes it easy to add or subtract biz days from a date. Here’s the steps on how to do it:

1. Choose the cell for the result.
2. Type “=WORKDAY(start_date, days, [holidays])” in the cell, replacing “start_date” with the starting date and “days” with number of biz days to be added or subtracted.
3. If needed, list any holidays that happen during the calculation inside the brackets after “days.”

Excel will only count weekdays when calculating the biz days, and it’ll ignore weekends and holidays. So it’s great for working out due dates for projects that have to avoid weekends and holidays.

Plus, you can use negative values for “days” if you need to subtract days from a date. But be careful not to use too many negative values, as it can cause an error if Excel tries to count back beyond a valid date range.

For a time-saving tip, make a formula template outside your main worksheet if you find yourself needing this calculation often, so you can quickly adjust it and reuse it when needed.

## Subtracting Days from a Date

I was working on my Excel sheet. I needed to add and subtract days from a given date. Adding was easy, but subtracting was tricky.

So, here’s a guide on how to do it. I’ll share two sub-sections:

1. The Simple Method using the DATE function
2. The Month-End Method using the EOMONTH function

Let’s start!

### Simple Method: Using the DATE Function

The “Simple Method: Using the DATE Function” is a straightforward way to add or subtract days from a given date in Excel. It uses the built-in DATE function. Here’s how to do it:

1. Select a cell to display the resulting date.
2. Type “=DATE(” into the cell.
3. After the opening parenthesis, type the year, month, and day arguments separated by commas. For example, to create a date for February 15th, 2022, type “2022,2,15” after “=DATE(“.
4. Close the parentheses and press enter.

This method lets you quickly add or subtract days. You can do this by changing the day argument before closing parentheses with a positive or negative integer.

Using this method is advantageous because it works even if you don’t have valid dates stored yet need to do calculations with time intervals quickly.

Pro tip – You can combine the DATE function with other functions like TODAY(), MONTH(), YEAR(), etc., to make versatile formulas for different purposes like calculating age and more.

The next heading is “Month-End Method: Using the EOMONTH Function“.

### Month-End Method: Using the EOMONTH Function

The EOMONTH function is another way to subtract days from a date in Excel. It can be used to find the end of a month or count the number of months between two dates. Here’s how:

1. Select the cell for the result.
2. Enter the formula: =EOMONTH(start_date,0). Where start_date is the date you want to end on.
3. Press Enter and check it.
4. To subtract days, put a minus sign (-) before the number of days. For example: =EOMONTH(A1,-15).
5. To make it easier, use cell references for start_date and days. Like this: =EOMONTH(A1,-B1).

This way is better since it doesn’t require entering various dates. It saves time and avoids errors.

For instance, it can help when closing books at month-end. It gives clarity on financial reports and makes sure all transactions are captured.

## FAQs about How To Add Days To A Date In Excel: Step-By-Step Guide

### 1. How do I add days to a date in Excel?

To add days to a date in Excel, you can use the simple formula: =Date + Number of days. For instance, if you want to add 10 days to a date, type “=Cell with the date + 10” in a separate cell, and the result will be a new date which is 10 days after the initial date.

### 2. Can I add negative days to a date in Excel?

Yes, you can add negative days to a date in Excel. All you need to do is use the same formula described in the first question but replace the number of days with a negative number. For example, if you want to subtract 15 days from a date, use “=Cell with the date – 15” in a separate cell.

### 3. Can I use a cell reference instead of a date in the formula?

Yes, you can use a cell reference instead of the date in the formula. Simply replace “Date” in the formula with the cell reference that contains the date you want to add days to. For example, if the cell A1 contains the initial date, you can use the formula “=A1 + 10” to add 10 days to it.

### 4. Is there a limit to the number of days I can add to a date in Excel?

There is no limit to the number of days you can add to a date in Excel. As long as the result fits into the date format that Excel recognizes, you can add any number of days.

### 5. How can I add weekdays only to a date in Excel?

To add weekdays only to a date in Excel, you can use the WORKDAY function. The syntax for the function is “=WORKDAY(Date, Number of days)”. This formula adds a specified number of weekdays to a starting date and excludes weekends.

### 6. What happens if I add days to a date that falls into a month with fewer days?

If you add days to a date that falls into a month with fewer days, Excel will automatically adjust the result to the last day of the month. For example, if you add 15 days to February 28th, the result will be March 15th instead of March 13th.
