Mastering Excel: How To Use Dates To Return Values Between Two Dates

Excel is an incredibly powerful tool for data management and analysis, and mastering its features can help you become more efficient in your work. One essential skill to have in your Excel toolkit is the ability to use dates effectively to return values between two dates. This can be especially useful for project management, tracking sales figures, or analyzing time-based data trends. In this blog post, we will explore tips, shortcuts, and advanced techniques for using dates in Excel. Plus, we'll discuss common mistakes to avoid and troubleshooting issues you might face along the way.

Understanding Dates in Excel

Before diving into returning values between two dates, it’s important to understand how Excel handles dates. Excel stores dates as serial numbers, which count the number of days since a base date. For example, January 1, 1900, is represented as 1, while January 2, 1900, is 2, and so on. This system makes it easy to perform calculations and comparisons with dates.

Formatting Dates

To effectively work with dates, ensure your data is formatted correctly. You can format dates by:

1. Selecting the date cells.
2. Right-clicking and choosing "Format Cells."
3. Navigating to the “Number” tab and selecting “Date.”
4. Choosing your preferred date format and clicking “OK.”

This formatting ensures Excel interprets your entries as dates, allowing for accurate calculations.

Using the IF Function with Dates

One of the most straightforward ways to return values between two dates is using the IF function. Here’s how it works:

Syntax of the IF Function

=IF(logical_test, value_if_true, value_if_false)

In this context:

• logical_test is the condition you are testing.
• value_if_true is what you want Excel to return if the condition is true.
• value_if_false is what Excel returns if the condition is false.

Example Scenario

Let’s say you have a sales report with the following data:

You want to find the total sales between January 1 and January 10, 2023.

Step-by-Step Guide

1. Use the IF function to check if the Sale Date is between the two dates.

=SUM(IF((A2:A5>=DATE(2023,1,1))*(A2:A5<=DATE(2023,1,10)), B2:B5))

2. Press Ctrl + Shift + Enter to enter it as an array formula. Excel will surround the formula with curly braces {} if done correctly.

Result

This formula will return $950, which is the total sales amount for that date range.

Advanced Techniques: Using the SUMIFS Function

While the IF function is great for simple conditions, the SUMIFS function is perfect for multiple criteria. The syntax for SUMIFS is:

=SUMIFS(sum_range, criteria_range1, criteria1, [criteria_range2], [criteria2], ...)

Example of SUMIFS

Using the same sales data, if you want to sum all sales between January 1 and January 10:

=SUMIFS(B2:B5, A2:A5, ">=2023-01-01", A2:A5, "<=2023-01-10")

This will yield the same result of $950.

Common Mistakes to Avoid

1. Incorrect Date Formatting: Always ensure your date cells are formatted correctly. If dates are entered as text, Excel may not recognize them.

2. Using Absolute References Incorrectly: If you plan to drag your formula down, make sure to use absolute references for criteria ranges where necessary.

3. Forgetting Array Formula: When using array formulas, don’t forget to press Ctrl + Shift + Enter!

Troubleshooting Issues

If your formulas are not working as expected:

• Check Cell Formats: Make sure the cell with the date is indeed formatted as a date, not text.

• Evaluate Formula: Use the “Evaluate Formula” feature found under the Formulas tab to see how Excel is interpreting your formula step-by-step.

• Check for Blank Rows: Blank rows in your data can lead to errors; make sure to clean your data before using formulas.
