## What Is HOUR Function In Excel?

The HOUR function in Excel is a powerful tool that allows users to extract the hour component from a particular time value. It can be particularly useful in scenarios where data analysis or calculations require isolating and manipulating the hour portion of a timestamp.

By using Hour function, professionals can easily determine specific hours in a given dataset and perform various operations on them. For example, they can use it to track peak hours of customer activity, calculate working hours for employees, or generate reports based on specific time intervals.

In the following example, we will illustrate the process of calculating the hour from a given time using the HOUR function in Excel.

To achieve this, the complete formula to be entered should be =HOUR(A2).

Once you have entered each value in the previous step, press the Enter key. As a result, the hour will be displayed as 7 in cell B2.

###### Key Takeaways

- The HOUR function is typically utilized in programming and data analysis to extract the hour component from a given time or timestamp.
- In Excel, time values play a crucial role in representing fractions of a date. These values are cleverly expressed as decimal numbers, allowing for precise calculations and comparisons.
- Excel errors can occasionally disrupt our meticulously crafted formulas. One such error is known as the #VALUE! Error arises when the provided serial_number fails to meet the criteria for a valid Excel time.
- The #VALUE! error serves as a gentle reminder to double-check our inputs and ensure they align with the expected time format. By adhering to Excel’s guidelines, we can navigate the vast sea of data with confidence and precision.

### Syntax

**Serial_number** – This is a required argument. This argument specifies the time from which we want to extract the hour. It should be noted that the function will return the hour value of the specified time. The hour value will be an integer ranging from 0 to 23, where 0 represents 12:00 AM, and 23 represents 11:00 PM.

The serial_number argument can be provided in the following formats:

- Decimal (serial number) representation of an Excel time.
- Text representation of a time.
- Reference to a cell containing a time.
- Time value obtained from another Excel function or formula.
