If you need to find the number of hours between two dates and times in Excel, you can use a simple formula with a writing pattern. This article will guide you through the steps required to calculate hours in Excel. The scenario could be anything from calculating hours worked to finding the duration of a specific project. The method remains the same regardless of the particular use case.

Before diving into the steps involved, let’s first discuss what a writing pattern is. In Excel, a writing pattern is a shorthand way of inputting data in a specific format. For example, if you want to input a date in the format of dd/mm/yyyy, you can use a writing pattern to ensure that Excel understands the format you are using. The writing pattern for this date format would be “dd/mm/yyyy”.

## Step 1: Input the Start and End Dates and Times

To begin the process of calculating hours in Excel, you first need to input the start and end dates and times. You can do this in any cell within your workbook, but it is recommended to create a dedicated section for this information. Start by inputting the start date and time in one cell, and the end date and time in another cell. Make sure to use a writing pattern for the dates and times to ensure that Excel understands the format you are using.

## Step 2: Calculate the Time Difference

Once you have input the start and end dates and times, the next step is to calculate the time difference between the two. You can do this by subtracting the start date and time from the end date and time. To do this, you can use the following formula:

=end_date_and_time - start_date_and_time

## Step 3: Convert the Time Difference to Hours

After calculating the time difference, you need to convert it to hours. To do this, you can use the following formula:

=(end_date_and_time - start_date_and_time) * 24

This formula multiplies the time difference by 24 to convert it to hours.

## Step 4: Format the Result

The final step is to format the result to display the number of hours in a clear and concise manner. You can do this by using a custom number format. To create a custom number format, right-click on the cell containing the result and select “Format Cells”. In the Format Cells dialog box, select the “Number” tab and choose “Custom” from the Category list. In the Type box, enter the following format:

This format will display the number of hours and minutes in the result.

## Conclusion

Calculating hours in Excel can be a simple process, but it requires a basic understanding of writing patterns and formulas. By following the steps outlined in this article, you can easily calculate the number of hours between two dates and times in Excel. Whether you need to calculate hours worked or the duration of a project, this method will provide you with an accurate and efficient solution.
