HOUR Formula Syntax
Example Use Case
Extracting the hour component from a time value
Understanding the HOUR Formula
The HOUR function in Excel extracts the hour component (0-23) from a time value. It's a time component tool for isolation—like breaking down times into parts or filtering based on the hour of day.
HOUR("3:45:30 PM") returns 15, extracting the hour in 24-hour format. It takes a single time argument (as serial number or text), delivering just the hour—useful for time analysis or conditional formatting based on time of day.
Why Use HOUR?
HOUR isolates time segments—think shift scheduling or time-based calculations. Its focused extraction enables hour-based sorting, filtering, or calculations, helping you work with specific time periods across your data.
Example with Sample Data
| Time | Formula | Result |
|---|---|---|
| 3:45:30 PM | =HOUR("3:45:30 PM") | 15 |
| 9:30 AM | =HOUR("9:30 AM") | 9 |
| NOW() | =HOUR(NOW()) | [Current hour] |
HOUR extracts just the hour: 3:45:30 PM gives 15 (24-hour format). It's a time component isolator.
