Function for Converting a Month Name to a Number

How to Convert Abbreviated Month Names to Numeric Values in Microsoft Access

When working with Microsoft Access programming, you might encounter situations where month names are provided in an abbreviated format, such as "Jan" for January or "Feb" for February. While this format is useful in some scenarios, there may be a need to store the month as a numeric value (e.g., 1 for January, 2 for February) in your database. Accomplishing this task efficiently requires minimal VBA (Visual Basic for Applications) code to create a translation between the abbreviation and its numeric equivalent.

Below, we outline a simple VBA function that takes the abbreviated month name as input and returns the corresponding numeric value. This approach minimizes complexity and integrates seamlessly into your Microsoft Access database workflows. Additionally, if you need to retrieve the full month name (e.g., "January" or "February") from a date-formatted field, we provide another helpful VBA function to streamline the process.
