Tips & Tricks: Troubleshooting the “String was not Recognized as a Valid Date Time” error

Have you ever received an error message stating, “String was not recognized as a valid DateTime”? If yes, you’ll need to configure regional settings found in your Windows Control Panel (not ShipWorks).  

Here’s how to find the setting for common Windows operating systems like Windows 7, 8, and XP. 


1. In Windows, click the Start Menu. For Windows 8 users, access the Start Menu by pressing the Windows key on your keyboard or moving your mouse to the lower left-hand corner and clicking Start.

2. Navigate to the Control Panel.For Windows 8 users, start typing “Control Panel” to prompt  the application to display.

3. Click on Region and Language (Windows 7) or click Change Date, Time, or Number Formats (Windows 8). For Windows XP users, clickRegional and Language Options > Customize > Customize Regional Options

4. Adjust the Short date and Long date formats to using a Month / Date / Year format. (Both Short date and Long date drop-down menus should display the “M” first.)
