As programmers, we often have to work with an array of data types when writing code. One of the most commonly used data types in VBA is the ‘Date’ data type, which allows us to manipulate dates and times in our code. In this blog post, we will explore the ‘Date’ data type in VBA, its syntax and storage, as well as provide five examples of VBA codes demonstrating its usage.

VBA DataType ‘Date’


The syntax for declaring a variable as the ‘Date’ data type in VBA is as follows:

Dim variableName As Date

This tells the VBA compiler to allocate memory space to store a date value and assign it to the variable name declared in the code.


The ‘Date’ data type in VBA is represented by a 64-bit floating-point number, where the integer part represents the number of days since December 31, 1899, and the decimal part represents the fraction of a day (or time).

For example, the value representing January 1, 2021, would be stored as 44197. This makes it easy to perform calculations and comparisons with dates in VBA.


The range of dates that can be stored in the ‘Date’ data type in VBA is from January 1, 100 to December 31, 9999. This means that the ‘Date’ data type is suitable for most date-related operations in our code.

Examples on VBA Date Data Type

Assigning a Date Value to a Variable

Dim startDate As Date
startDate = #1/1/2021#

In this example, we declare a variable called “startDate” and assign it a value of January 1, 2021, using the “#” symbol to indicate a date value.

Using Date Functions to Manipulate Dates

Dim currentDate As Date
currentDate = Date
MsgBox "Today's date is " & Format(currentDate, "dd/mm/yyyy")

This code snippet uses the built-in VBA function ‘Date’ to retrieve the current date and then formats it using the ‘Format’ function before displaying it in a message box.

Using Date Functions to Determine the Age

Dim birthDate As Date
birthDate = #10/5/1990#
Dim age As Integer
age = DateDiff("yyyy", birthDate, Date)
MsgBox "You are " & age & " years old."

Here, we declare a variable representing a birth date and use the ‘DateDiff’ function to calculate the difference in years between the birth date and the current date, giving us the age of the individual.

Calculating the Number of Days Between Two Dates

Dim startDate As Date
Dim endDate As Date
startDate = #1/1/2021#
endDate = #5/31/2021#
Dim numDays As Integer
numDays = DateDiff("d", startDate, endDate)
MsgBox "There are " & numDays & " days between " & startDate & " and " & endDate & "."

This code snippet uses the ‘DateDiff’ function to calculate the number of days between two dates and display the result in a message box.

Converting a String to a Date Value

Dim dateStr As String
dateStr = "2020-12-31"
Dim convertedDate As Date
convertedDate = CDate(dateStr)
MsgBox "The converted date is " & Format(convertedDate, "mm/dd/yyyy")

In this example, we declare a variable containing a date in string format and use the ‘CDate’ function to convert it into a ‘Date’ data type before formatting and displaying it in a message box.


In this blog post, we have explored the ‘Date’ data type in VBA, its syntax and storage, and provided five examples of VBA codes demonstrating its usage. By understanding how the ‘Date’ data type works and knowing how to use it in our code, we can perform various date-related operations efficiently.
