How To Subtract Dates In Excel

Are you struggling with subtracting dates in Excel? Let us help you out! You don’t have to be an Excel expert to learn how to subtract dates – our simple guide walks you through the steps for easy understanding.

Understanding the Concept of Date Subtraction in Excel

For subtraction of dates in Excel, you need to understand that it sees the dates as numbers. Ensure that the range for calculations only has date values – no non-date values. Check if the result is correct by counting back from a later date to an earlier one. Also, start each formula with the cell containing newer data.

Formatting dates correctly is important for accurate subtraction in Microsoft 365/Office 2019.

Formatting Dates in Excel for Accurate Subtraction

Let’s format those dates to make sure our calculations are accurate!

Hold down the “Ctrl” key and click each cell you want to highlight.

In the “Home” tab, select “Format Cells” from the “Number” area.

In the Format Cells dialogue, click on the “Number” tab and select “Date.”

Pick a date format that fits your data. You can also choose custom formats.

Once done, click “OK”.

It’s important to format dates before subtracting them in Excel. Incorrect formatting can lead to wrong results. So, always make sure all of your date cells are formatted the same way before performing calculations.

A friend of mine faced this problem once, while dealing with a huge set of data. They were trying to calculate the number of days between two dates but kept getting wrong results. After checking, they found some sheets were using different date formats. Once they formatted the dates consistently across all sheets and workbooks, their calculations became correct.

Basic Date Subtraction Methods in Excel

Do you find subtracting dates in Microsoft Excel hard? It’s a common problem for learners. Frustration may come when you don’t know how to begin! In this article, I’ll cover the basics of date subtraction in Excel. We’ll focus on two main methods – the DATEDIF and YEARFRAC functions. We’ll learn to use both formulas in spreadsheets and get a better understanding of date subtraction in Excel. By the end, you’ll be able to solve date-related issues quickly!

Using the DATEDIF Function

1. First, select a blank cell to display the date subtraction result.
2. Type the formula: =DATEDIF(start_date,end_date,unit). Replace start_date and end_date with your dates and unit with a time period (days, months, or years).
3. Press Enter to calculate.
4. Result appears in that cell.

Important: DATEDIF isn’t like other Excel functions. It’s not in the built-in formula list and doesn’t have help documentation.

The syntax of DATEDIF can be tricky. Three arguments must be input: start date, end date, and time units. If these aren’t precise, then the result will be wrong.

Fun fact: DATEDIF was made for Lotus 1-2-3 spreadsheet program. It’s used in other software too, like Microsoft Excel.

Next, we’ll learn how to use YEARFRAC Function for subtracting dates.

Subtracting Dates with the YEARFRAC Function

To use the YEARFRAC function, select the cell where the result should appear. Type “=YEARFRAC(start_date,end_date)” and replace “start_date” and “end_date” with cell references or actual dates. Press enter. The result will show up in the cell.

YEARFRAC is a reliable way to calculate fractional years accurately. It’s different than other methods like subtracting dates or using DATEDIF.

If you want to be productive and accurate when subtracting dates, it’s important to learn the basics. This is the foundation for more advanced date subtraction techniques in Excel.

Advanced Date Subtraction Techniques in Excel

Subtracting dates in Excel can be tricky! So, let’s delve into some advanced techniques. Firstly, we’ll look at the NETWORKDAYS function. It calculates business days between two dates. Next, the EDATE function lets us subtract months from a date. Then, the EOMONTH function works out months between two dates. Last, the WORKDAY function subtracts workdays from a date. After this, you’ll have mastered all the tricks for date subtraction in Excel!

Subtracting Dates with the NETWORKDAYS Function

To use the =NETWORKDAYS() function, select the cell where you want to display the result. Then, type =NETWORKDAYS( followed by two dates in quotation marks (” “), separated by a comma. Include any holidays or non-working days in curly brackets { } if required. Close the formula with ).

This function makes calculations easier, saves time, and reduces errors. For example, if you want to find out how many working days between January 1st, 2022 and January 10th, 2022, use =NETWORKDAYS(“01/01/2022”, “01/10/2022”). This will return a value of 7.

Remember to enter holidays correctly for them to be excluded from the calculation. You can also customize this function by adding arguments like start and end dates for work hours and custom holiday lists.

The EDATE Function is another way to quickly subtract months from a given date. We will discuss this further in our article.

Using the EDATE Function to Subtract Months

To subtract a specific amount of months from a given date, use the EDATE function! Simply type it in the formula bar and fill out the start date and number of months to subtract. Hit enter to get the result.

This technique also adjusts for leap years, so no matter the years, you’ll get an accurate result. Plus, you can use it to analyze data and track trends over time – like monthly sales or inventory levels.

And if you want to add months, just put in a negative value!

Now that we’ve covered how to use the EDATE Function to Subtract Months, let’s move on to the EOMONTH Function.

Using the EOMONTH Function to Subtract Months

Want to subtract months from a date in Excel? Use the EOMONTH function! It lets you subtract or add a specified number of months to a given date. Here’s how:

1. Open Excel and enter the starting date in any cell.
2. Enter the formula =EOMONTH(start_date, -number_of_months) in an adjacent cell.
3. Replace “start_date” with the reference to your starting date, eg. A1 if it is in cell A1.
4. Replace “number_of_months” with the number of months you want to subtract from the start date.

EOMONTH ensures results are accurate and consistent. Plus, it saves time and reduces errors. To find the last day of a quarter or year, change -number_of_months accordingly.

Another advanced technique to subtract dates is the WORKDAY function. It calculates business days between two dates, excluding weekends and holidays. You just need two cell references and no consideration for weekends/holidays.

Combining EOMONTH and WORKDAY lets you easily find the end date of a project. More about WORKDAY in our next heading.

Using the WORKDAY Function to Subtract Workdays

I once had an experience at my previous job where I had to complete a financial model in four weeks. We had three weeks to complete it, but the client wanted changes. This left us with two weeks to finish 70% of the model. To help us adjust our work schedules, my boss used the WORKDAY Function.

This ensures only working days are considered when subtracting dates. It’s also useful for calculating due dates for projects. You can duplicate it for other rows or columns throughout the project plan.

Here’s a step-by-step guide on how to use it:

1. Type ‘=WORKDAY(‘ in an adjacent cell to the one with the original date.
2. Enter the ‘start_date‘, which includes weekends.
3. Enter a comma and then type in how many workdays you want to subtract.
4. Enter a comma and add holiday dates in an array using Excel’s holiday list feature or manually.

Remember, negative numbers indicate the move backward while positive numbers move forward. And don’t forget to use brackets correctly, or errors may occur.
