| Objective | Value Returned by function |
|---|---|
| Aim to get the Hour value as Number | HOUR Function will return a numeric values from the input hour value. |
HOUR Function: A Syntax:
=HOUR(hour_value)
- hour_value: It should be a valid excel hour value.
Important Notes About HOUR Function:
- The HOUR function in Excel extracts the hour value from a given time and returns a number between 0 and 23.
- For Example, if the time is 11:00 AM, the HOUR function will return the numeric value as 11. It requires only one argument, serial_number, which must be a valid Excel date or Excel time.
Basic Example of using HOUR Function in Excel
- You can enter time values as text (e.g., “9:25 PM”) or as decimal numbers (e.g., 0.5, which equals 12:00 PM). The HOUR Function returns the equivalent numeric value.
HOUR Function returns the numeric value by ignoring the minutes from the given Hour value
HOUR Function returns the numeric value equivalent to the decimal value.
- In the above image, The input value is 0.34 decimal value but the HOUR Function converts into a valid Excel time and returns the numeric value equivalent to the input hour value. So the HOUR function considers the decimal value as 08:09 AM and returns the numeric value as 8 in the output cell.
