## 8 Examples to Understand and Use WEEKDAY Function in Excel

Excel offers different applications using the **WEEKDAY** function. We’ll try to discuss those as examples.

### Example 1: Basic Examples of WEEKDAY Function

If the days are given in date format and do not need to input the return_type value, you may utilize the following formula in the **D5 **cell.

`=WEEKDAY(C5)`

Here, **C5 **is the **Joining Date** of **Robert**.

- Secondly, press
**ENTER**. - Thirdly, use the
**Fill Handle**by dragging down the cursor while holding it at the**right-bottom**corner of the**D5**cell like this.

- Eventually, the outputs will be like this.

But if the return type is **2** and **16** respectively for the same dataset. You may use the following formula in the **D5 **cell.

- When the value of return_type is
**2**:

`=WEEKDAY(C5,2)`

- When the value of return_type is
**16**:

`=WEEKDAY(C5,16)`

**D5**cell like this.

`=WORKDAY(B5,C5,G5:G9)`

- Eventually, press
**ENTER** - Lastly, use the
