The following macro gets the year of a date. To declare a date, use the Dim statement. To initialize a date, use the DateValue function.

Result:

Year of a Date in Excel VBA

Note: Use Month and Day to get the month and day of a date.

DateAdd

To add a number of days to a date, use the DateAdd function. The DateAdd function has three arguments. Fill in "d" for the first argument to add days. Fill in 3 for the second argument to add 3 days. The third argument represents the date to which the number of days will be added.

Code:

Dim firstDate As Date, secondDate As Date

firstDate = DateValue("Jun 19, 2010")
secondDate = DateAdd("d", 3, firstDate)

MsgBox secondDate

Result:

DateAdd

Note: Change "d" to "m" to add a number of months to a date. Place your cursor on DateAdd in the Visual Basic Editor and click F1 for help on the other interval specifiers. Dates are in US Format. Months first, Days second. This type of format depends on your windows regional settings.

Current Date and Time

To get the current date and time, use the Now function.

Code:

MsgBox Now

Result:

Current Date and Time

Hour, Minute, Second

The get the hour of a time, use the Hour function.

Code:

MsgBox Hour(Now)

Result:

Hour of the Current Time

Note: Use Minute and Second to get the minute and second of a time.

TimeValue

The TimeValue function converts a string to a time serial number. The time's serial number is a number between 0 and 1. For example, noon (halfway through the day) is represented as 0.5.

Code:

MsgBox TimeValue("9:20:01 am")

Result:

TimeValue

Now, to clearly see that Excel handles times internally as numbers between 0 and 1, add the following code lines:

Dim y As Double
y = TimeValue("09:20:01")
MsgBox y

Result:

Time Serial Number
