Suppose you are in a situation where you have to calculate weeks from some given date range. And you need to calculate cost estimation by using those weeks, for instance. So how will you calculate those weeks? Well, you can calculate those using your calculator, or you can do it in Excel in a faster way. Guess what our topic is today? That’s right! This is how you can **calculate the number of weeks between two dates** in Excel.

Let’s assume we have a dataset, namely **“Timeline for Everest Base Camp Expedition”. **You can use any dataset suitable for you.

Here, we have used the **Microsoft Excel 365 **version; you may use any other version according to your convenience.

## 1. Using INT Function

Firstly, you can calculate the number of weeks between two given dates by doing a simple mathematical calculation. We will subtract two given dates and then divide them by** 7 **to get the number of weeks. To get an integer value, we will use the **INT function**.

📌 **Steps:**

- Initially, select the
**D5**cell and apply the following formula given below.

`=INT((C5-B5)/7)`

Here, **C5 **and **B5 **cells represent **“Ending Date”** and **“Starting Date”** respectively. In this formula, the mathematical subtraction returns the number of days first. Later, when the output is divided by **7**, we get the number of weeks, but not in integers. That’s why we need to use the **INT **function to get the desired output.

- Then press
**ENTER**.

- To get the rest of the value, drag the
**Fill Handle**tool from**D5**cell to**D15**.

- So, the final output will be as given below.

## 2. Applying ROUNDDOWN Function

The **ROUNDOWN function** returns the same output as found in the earlier method. Here, the output has been rounded down by using the **ROUNDDOWN** formula.

📌 **Steps:**

- To begin, put the following formula in the
**D5**

`=ROUNDDOWN((C5-B5)/7,0)`

- Then press
**ENTER**.

- Subsequently, drag the
**Fill Handle**

- As a result, your final output will be as follows.

## 3. Utilizing the DATEDIF Function

In this method, we will learn how to calculate the number of weeks between two dates using the **DATEDIF function**. The method is not hard. All you need to know is how you use the **DATEDIF** function to do your task.

📌 **Steps:**

- As we do before, click on cell
**D5**and then type the following formula.

**=ROUNDDOWN((DATEDIF(B5, C5, “d”) / 7), 0)**

- Press
**ENTER**.

- Finally, drag the
**Fill Handle**tool from the**D5**cell to**D15**to get the rest of the value.

- The output will look like the one below.

## 4. Employing WEEKNUM Function

By using the **WEEKNUM function**, you can calculate the number of weeks between two given dates. But one thing you should keep in mind is that this function will give you the correct output if two dates (from which you want to find the number of weeks) are in the same year. Sounds Confusing? Not at all! You will understand the functionality if you look at the example that I have given below.

Suppose we have a data set that looks like this:

Now follow the steps that are given below.

📌 **Steps:**

- First, click on cell
**D5**and type the following formula.

`=WEEKNUM(B5)-WEEKNUM(B5)`

Basically, the **WEEKNUM **returns the week number in a year from any specific date. For this reason, we have to use the function twice for each date.

- Press
**ENTER**.

- Drag the
**Fill Handle**tool as we have shown below.

** **

- Thus, we get the values of the weeks as follows.

## Calculating the Number of Weekdays Between Two Dates in Excel

Now, we can calculate our weekdays between given dates employing the **DATEDIF** function in our Excel sheet.

📌 **Steps:**

- Type the following formula in
**D5**

`=(DATEDIF(B5, C5, "d"))`

In this case, we use the **“d”** argument as we want to find the number of days between two dates.

- Then press
**ENTER**.

** **

- Then drag the
**Fill Handle**tool from the**D5**cell to**D15**to get the other value.

## Calculating the Number of Months Between Two Dates in Excel

The Excel **DATEDIF **function also allows you to determine the **number of months between two dates**, like** counting days.**

📌 **Steps:**

- Type the following formula.

`=(DATEDIF(B5, C5, "m"))`

In this formula,** “m”** gives Excel the direction to count the month as we have previously learned for counting days.

- Then press
**ENTER**.

- Drag the
**Fill Handle**tool from the**D5**cell to the**D15**cell to get the other value

- Finally, the output you get is as follows:

## Calculating the Number of Years Between Two Dates in Excel

Similarly, you can also find the **number of years between two dates** utilizing the **DATEDIF** function in Excel.

📌 **Steps:**

- First, type the following formula for
**D5**

`=(DATEDIF(B5, C5, "y"))`

- Secondly, press
**ENTER**.

- Next, drag the
**Fill Handle**

- In turn, the output you get is as follows:
