# How to Count the Average Between Two Dates in Excel

In our daily work, we usually have the problem of counting the average of a period. If the given dates are continuous, we can handle this situation very well, and if the dates are discontinuous, how do we count the average for different periods? In this article, we will use some examples to show you how to** count the average for two dates by Average formula** in different situations.

**Count the Average Between Continuous Dates**

First prepare a table with given dates and sales.

You can see the given dates are continuous, so we can count average by Average formula directly.

**Step 1:** In B7, enter the formula **=AVERAGE(B2:B4)** to count the average between dates ** 1/28/2019** and

**.**

`3/28/2019`

**Step 2:** Click **Enter** to get the result.

**Count the Average Between Discontinuous Dates**

If in above table the dates are discontinuous and unordered, how can we count the average of sales? See screenshot below.

You can follow below steps to count the average for two discontinuous dates.

**Step 1:** Prepare another table to save the **Start Date, End Date and Average**.

**Step 2:** In **Start Date** enter the start date of the period you want to count the average. In **End Date** enter the end date of the period you want to count the average. For example, we count the average for period ** 2/28/2019** and

**.**

`4/28/2019`

**Step 3:** In Average, enter the formula **=AVERAGE(IF((A2:A7>=B10)*(A2:A7<=B11),B2:B7)).**

In above formula, A2:A7 is the given date range, B10 is the start date, B11 is the end date, B2:B7 is the sales range.

**Step 4:** After entering the formula, click ** Ctrl + Shift + Enter** to get the result.

Check the formula bar, you can find the formula is displayed as below. That’s an array formula.

**Notes:**

**1.** In step 4, if we just click **Enter** after entering the formula, then we will get an error here. That’s because above formula is an array formula.

**2.** If we just want to use a normal formula to count the average and click **Enter** to get the result, we can use below formula **=SUMPRODUCT(–(A2:A7>=B10),–(A2:A7<=B11),B2:B7)/SUMPRODUCT(–(A2:A7>=B10),–(A2:A7<=B11))**. We can get the same result.
