If you are writing macros for Excel, you may have a need to determine the hour represented by a particular date and time value. For instance, you might want to know the hour of the day in which the macro is running. You can ascertain this information by using the HOUR function, as follows:
iThisHour = Hour(Now())
When executed, iThisHour will be equal to the current hour number, which ranges from 0 to 23. Notice that this example uses the Now() function. If you want to determine the hour number for a different date and time value, simply substitute that value in place of the Now() function.

In VBA you don't need to include the parentheses if there are no arguments, so Hour(Now) is the same as Hour(Now()). There's no harm in leaving them, other than you might be tempted to put in an argument where there is none.
In contrast, in Excel you must use the parentheses, as this is how Excel knows you are referencing a function. =HOUR(NOW()) will give you the correct result, whereas =HOUR(NOW) will display the #NAME? Error.
