HOUR Function: A Syntax: =HOUR(hour_value) =HOUR(hour_value) hour_value: It should be a valid excel hour value. hour_value: It should be a valid excel hour value. 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. 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. extracts the hour value given time 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. 11:00 AM 11 argument serial_number Excel date Excel time 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. 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. text decimal numbers 0.5 12:00 PM 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. 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. 0.34 decimal value Excel time numeric value equivalent hour value 08:09 AM numeric value as 8 Decimal Values Equivalent Hour Value in Excel 0.01 12:14 AM 0.02 12:29 AM 0.03 12:43 AM 0.04 12:57 AM 0.05 1:12 AM 0.06 1:26 AM 0.07 1:41 AM 0.08 1:55 AM 0.09 2:10 AM 0.10 2:24 AM 0.125 3:00 AM 0.15 3:36 AM 0.1667 4:00 AM 0.20 4:48 AM 0.25 6:00 AM 0.30 7:12 AM 0.3333 8:00 AM 0.375 9:00 AM 0.40 9:36 AM 0.50 12:00 PM (Noon) 0.55 1:12 PM 0.5833 2:00 PM 0.60 2:24 PM 0.625 3:00 PM 0.6667 4:00 PM 0.70 4:48 PM 0.75 6:00 PM 0.80 7:12 PM 0.8333 8:00 PM 0.875 9:00 PM 0.90 9:36 PM 0.9167 10:00 PM 0.95 11:24 PM 1.00 12:00 AM (Midnight) Decimal Values Equivalent Hour Value in Excel 0.01 12:14 AM 0.02 12:29 AM 0.03 12:43 AM 0.04 12:57 AM 0.05 1:12 AM 0.06 1:26 AM 0.07 1:41 AM 0.08 1:55 AM 0.09 2:10 AM 0.10 2:24 AM 0.125 3:00 AM 0.15 3:36 AM 0.1667 4:00 AM 0.20 4:48 AM 0.25 6:00 AM 0.30 7:12 AM 0.3333 8:00 AM 0.375 9:00 AM 0.40 9:36 AM 0.50 12:00 PM (Noon) 0.55 1:12 PM 0.5833 2:00 PM 0.60 2:24 PM 0.625 3:00 PM 0.6667 4:00 PM 0.70 4:48 PM 0.75 6:00 PM 0.80 7:12 PM 0.8333 8:00 PM 0.875 9:00 PM 0.90 9:36 PM 0.9167 10:00 PM 0.95 11:24 PM 1.00 12:00 AM (Midnight) Decimal Values Equivalent Hour Value in Excel Decimal Values Decimal Values Equivalent Hour Value in Excel Equivalent Hour Value in Excel 0.01 12:14 AM 0.01 0.01 12:14 AM 12:14 AM 0.02 12:29 AM 0.02 0.02 12:29 AM 12:29 AM 0.03 12:43 AM 0.03 0.03 12:43 AM 12:43 AM 0.04 12:57 AM 0.04 0.04 12:57 AM 12:57 AM 0.05 1:12 AM 0.05 0.05 1:12 AM 1:12 AM 0.06 1:26 AM 0.06 0.06 1:26 AM 1:26 AM 0.07 1:41 AM 0.07 0.07 1:41 AM 1:41 AM 0.08 1:55 AM 0.08 0.08 1:55 AM 1:55 AM 0.09 2:10 AM 0.09 0.09 2:10 AM 2:10 AM 0.10 2:24 AM 0.10 0.10 2:24 AM 2:24 AM 0.125 3:00 AM 0.125 0.125 3:00 AM 3:00 AM 0.15 3:36 AM 0.15 0.15 3:36 AM 3:36 AM 0.1667 4:00 AM 0.1667 0.1667 4:00 AM 4:00 AM 0.20 4:48 AM 0.20 0.20 4:48 AM 4:48 AM 0.25 6:00 AM 0.25 0.25 6:00 AM 6:00 AM 0.30 7:12 AM 0.30 0.30 7:12 AM 7:12 AM 0.3333 8:00 AM 0.3333 0.3333 8:00 AM 8:00 AM 0.375 9:00 AM 0.375 0.375 9:00 AM 9:00 AM 0.40 9:36 AM 0.40 0.40 9:36 AM 9:36 AM 0.50 12:00 PM (Noon) 0.50 0.50 12:00 PM (Noon) 12:00 PM (Noon) 0.55 1:12 PM 0.55 0.55 1:12 PM 1:12 PM 0.5833 2:00 PM 0.5833 0.5833 2:00 PM 2:00 PM 0.60 2:24 PM 0.60 0.60 2:24 PM 2:24 PM 0.625 3:00 PM 0.625 0.625 3:00 PM 3:00 PM 0.6667 4:00 PM 0.6667 0.6667 4:00 PM 4:00 PM 0.70 4:48 PM 0.70 0.70 4:48 PM 4:48 PM 0.75 6:00 PM 0.75 0.75 6:00 PM 6:00 PM 0.80 7:12 PM 0.80 0.80 7:12 PM 7:12 PM 0.8333 8:00 PM 0.8333 0.8333 8:00 PM 8:00 PM 0.875 9:00 PM 0.875 0.875 9:00 PM 9:00 PM 0.90 9:36 PM 0.90 0.90 9:36 PM 9:36 PM 0.9167 10:00 PM 0.9167 0.9167 10:00 PM 10:00 PM 0.95 11:24 PM 0.95 0.95 11:24 PM 11:24 PM 1.00 12:00 AM (Midnight) 1.00 1.00 12:00 AM (Midnight) 12:00 AM (Midnight) From the above table, you can find the decimal values and equivalent hour values.
