Subtracting the difference between two dates in Excel is a straightforward process that can be achieved using different methods. Each method provides specific results, allowing you to calculate the time intervals in days, weeks, months, or years between the given dates.
Type 1: Find the Difference in Days
To find the difference in days between two dates in Excel, follow these steps:
Step 1 Enter the start and end dates in separate cells, such as A1 and A2.
Step 2 Use the DATEDIF function to calculate the difference. In an adjacent cell, type =DATEDIF(A1, A2, "d")
where A1 is the cell containing the start date, and A2 is the cell containing the end date.
Step 3 Press "Enter" to get the result, which will be the number of days between the two dates.
Type 2: Find the Difference in Weeks
To find the difference in weeks between two dates in Excel, follow these steps:
Step 1. Insert your start and end dates in two different cells.
Step 2. Use the DATEDIF formula in another cell. Type =DATEDIF(A1, A2, "d")
Step 3. Excel does not allow the usage of the lowercase letter "w" to compute weeks. Close the DATEDIF formula with a closing parenthesis and divide it by 7 using a forward slash and the number 7, like this:
Step 4. Press "Enter" to get the result, which will be the number of weeks between the two dates.
The result may appear as a whole number or a decimal, depending on the dates entered.
Type 3: Find the Difference in Months
To find the difference in months between two dates in Excel, follow these steps:
Step 1: Use the DATEDIF formula with A2 as the first argument (start_date) and B2 as the second argument (end_date).
Step 2: For the third argument (unit), use "m" to get the difference in the number of months.
Step 3: Press Enter to get the result
Type 4: Find the Difference in Years
To find the difference in years between two dates in Excel:
Step 1. Place start and end dates in separate cells.
Step 2. Use the DATEDIF function: "=DATEDIF(start_date, end_date, "y")".
Step 3. Press "Enter" to get the difference in years.
Part 3: What Details Should Be Paid Attention to When Calculating?
When calculating the difference between two dates in Excel, it's essential to pay attention to the following details:
The DATEDIF function is not a part of the standard Excel formulas but can be utilized within Excel for date calculations.
When using the YEARFRAC and DATEDIF functions, ensure that the end_date is always greater than the start_date to avoid encountering the #NUM! error.
The unit "M" extracts the number of complete months between two date values, while the unit "Y" returns the years between the two dates. Pay attention to these units for accurate calculations.
