Excel HOUR Function

The Microsoft Excel HOUR function is a practical tool designed to extract the hour from a time value. It converts a given time into an hour format, ranging from 0 (12:00 AM) to 23 (11:00 PM), enabling users to manipulate and work with time-related data easily.

This function falls under the Excel Date and Time Functions category, a crucial aspect for those dealing with scheduling, logging, or any time-specific records in Excel.

Excel HOUR Function Syntax:

=HOUR(serial_number)

In this syntax:

• serial_number is the time value from which you want to extract the hour. It can be a cell reference, a time entered as text, or a time serial number generated by other Excel functions.

Excel HOUR Function Parameters:

The HOUR function has a single parameter:

• serial_number: This represents the time you wish to convert into hours. Excel manages dates and times as serial numbers, where time is a fraction of a day. It’s important to ensure that the time is input correctly to get the desired hour value.

Return Value:

This function returns an integer between 0 and 23, representing the hour of the time value provided.

Examples:

• To extract the hour from the time in cell A1: =HOUR(A1)
• If cell A2 contains 15:45 (3:45 PM), the formula =HOUR(A2) returns 15.
• For a direct time input: =HOUR("18:30") gives a result of 18.

Use Cases:

The HOUR function is widely used in scenarios such as:

• Scheduling: Determining the hour component of start and end times for shifts or events.
• Logging: Extracting hours from timestamps in log files.
• Reporting: Generating reports that require the hour part of times, such as hourly sales data.

For effective utilization, combine the HOUR function with other date and time functions to extract or manipulate specific components of timestamps in your data analysis tasks.

Common Errors:

• #VALUE! Error: Occurs if the supplied argument is not a valid time. Ensure your time values are correctly formatted.
• Incorrect Result: Ensure AM/PM is correctly applied when entering times as text to prevent unexpected results.

Compatibility:

The HOUR function is widely compatible across different versions of Excel. However, always check your Excel version for the complete function support if you encounter issues.
