How to use Now function in VBA?

In VBA (Visual Basic for Applications), the `Now` function is used to get the current date and time. The `Now` function does not require any arguments and can be used in your VBA code to insert the current date and time into a cell, variable, or use it for time-stamping and calculations.

Here’s how you can use the `Now` function in VBA:

    Sub InsertCurrentDateTime()
        ' This will insert the current date and time into cell A1 of the active sheet
        ActiveSheet.Range("A1").Value = Now
    End Sub

    Sub GetCurrentDateTime()
        Dim currentDateTime As Date
        currentDateTime = Now
        Debug.Print "The current date and time is: " & currentDateTime
    End Sub

    Sub CalculateTimeDifference()
        Dim startTime As Date
        Dim endTime As Date
        Dim timeDifference As Double

        ' Record start time
        startTime = Now
        
        ' (Your code that performs tasks goes here)

        ' Record end time
        endTime = Now
        
        ' Calculate the difference in seconds
        timeDifference = (endTime - startTime) * 24 * 60 * 60
        Debug.Print "The operation took " & timeDifference & " seconds to complete."
    End Sub

    Sub ShowCurrentDateTime()
        MsgBox "The current date and time is: " & Now
    End Sub

Insert the current date and time into a cell:
Assign the current date and time to a variable:
Use the current date and time in a calculation:
Display a message with the current date and time:

Remember that `Now` returns both the date and time. If you need just the date without the time component, you would use the `Date` function, and for just the time component, use the `Time` function.

To utilize these functions, you can simply call them directly in your VBA procedures wherever you need the current date and time.
