Excel VBA Now Function
NOW is a date and time function in both VBA which is used to get the current system date and time, just like the worksheet function which does not take any arguments in it, in VBA now function also does not takes any arguments, the return output for this function is date.
VBA NOW function is similar to the one in the excel worksheet function. Like the DATE function in VBA, “NOW” too doesn’t have parameters to pass in. We just need to pass the function with closed parenthesis or no need for parenthesis as well. By using the DATE function in VBA, we can generate the current date as showing the system we are working on. However, I have seen situations where we need current time along with the date as well. In excel, we can do many varieties of things; similarly, we can generate current date and time with a simple function called NOW in excel.
The formula of the VBA NOW is simple.
Example of NOW Function in VBA Excel
Look at the simple example of the NOW function in VBA. Follow the below steps to write the VBA code and have a fair bit of knowledge on NOW as well as writing the code.
Step 1: Start the subprocedure by giving a macro name.
Sub Now_Example1() End Sub
Step 2: Declare the variable as “Date.” The reason why we need to declare the variable as “Date” because our end result is in Date and Time format.
Sub Now_Example1() Dim k As Date End Sub
Step 3: Assign the value to the variable “k” by applying VBA NOW function.
Sub Now_Example1() Dim k As Date k = Now End Sub
Step 4: Now show the value of the function NOW, which we have assigned to the variable “k” in the message box in VBA.

Sub Now_Example1() Dim k As Date k = Now MsgBox k End Sub
Ok, we are done.
Run the code using the F5 key or manually and see what the result is.
The result shows 4/15/2019 at 5:03:35.
My computer date format is “mm-dd-yyyy.”
We can also change the date format by using the FORMAT function. Below is the code to change the date format.
Sub Now_Example1() Dim k As Date k = Now MsgBox Format(k, "DD-MMM-YYYY HH:MM:SS") End Sub
Run the code and see the difference.
Now we have a proper date and time format. With this format, anybody can understand the date and time format.
Volatile in Nature:
As you can see in the first example, we got the time result as 5:03:35, and in the second example, we go the result as 17:19:02. So this shows that the NOW function is a volatile function that changes every second.
Alternative to Timer Function in VBA
As an alternative to VBA TIMER, we can use the “VBA NOW” function to calculate the total time taken by the macro to complete the task.
Use the below code to calculate the time taken by your code.
Sub TotalDuration() Dim k As Date k = Now ' ' 'Enter your code here ' ' ' MsgBox "Total Time Taken by the macro to complete the task is : " & _ Format((Now - k), "HH:MM:SS") End Sub
In the green-colored area, copy and paste your code.
Execute the code by pressing the F5 key or press the run button. As soon as it completes the execution, we will get the time taken by the macro to complete the task message in the message box. Below is an example of the same.
Like this, we can use NOW function in many ways in VBA.
