### Method 1 – Using Subtraction

If we know the starting time and the finishing time, we can calculate hours by using subtraction.

#### Case 1.1. Time Value Difference Less than 24 Hours

Suppose we have the following dataset with column headers as **Start Time**, **Finish Time**. We need to** calculate the Total Hours **in **Column D**. Here, we can see that the time value difference is **less** than **24** hours.

- Apply the simple subtraction formula in the
**D5:**

`=C5-B5`

- Press
**Enter**to get the output. - Use the
**Fill Handle**by dragging down the cursor while holding the**right-bottom**corner of the**D5**cell.

- Eventually, weâ€™ll get the
**Total Hours**as output like this.

#### Case 1.2. Time Value Difference More than 24 Hours

In the following dataset, the time difference between the **Start Time** and **Finish Time** is more than **24** hours.

- Write the following formula in the
**D5**cell:

`=(C5-B5)*24`

- Press
**Enter**. - Use the
**Fill Handle**to get all the outputs.

### Method 2 – Calculating Working Hours Between Two Consecutive Days

Suppose we have the following dataset where we need to calculate hours between two consecutive days.

- Write this formula in the
**D5**cell.

Let’s find the hours in **Column D** of the following dataset.

- Write the formula in the
**D5**cell:

`=TEXT(C5-B5,"[hh]:mm")`

Here, **hh **and **mm **refer to **Hours **and **Minutes **respectively. **[hh]:mm** refer that weâ€™ll get the output in this format i.e. first hour then a minute.

- Press
**Enter**. - Use the
