Excel SECOND Function Syntax

SECOND(serial_number)

Arguments

serial_number The time value for which you want to find the second value. You can use a text string like "8:30", or a decimal number like 0.24125 which means 5:47:24 AM in Excel.

Examples

The SECOND function only needs a single argument to execute: serial_number. Although the argument parameter contains "number" in its name, Excel can evaluate time values included in a string as well. Simply enter the serial_number as a static value, a cell reference, or a return value from a function that can generate a time value. Functions such as TIME and TIMEVALUE can be used for this purpose.

=SECOND("12:30:15") returns 15

=SECOND(0.256) returns 38

=SECOND(TIMEVALUE("21:36:107")) returns 47 because the function resets the second value after 60.

Tips

  • Excel stores date and time as numbers. Excel assumes that the date 1/1/1900 is “1″, and increases this number by 1 for each day. In a similar way, the time values must be between 0 and 999999999. For example; 6:00 AM is equal to 0.25. Because of this, the TIMEVALUE function in Excel returns a number that is displayed as a time value.
  • A time value in Excel is 0 on 12:00 AM.
  • VBA also has a function that shares same name. The usage of that function is also very similar to its Excel counterpart.
 Dim MyTime, MySecond
MyTime = #4:35:17 PM#    ' Assign a time.
MySecond = Second(MyTime)    ' MySecond contains 17. 


    

  • You can use HOUR and MINUTE functions to get hour and minute values from a time value respectively.

Issues
