how do I do a date format swith

Hi M, welcome to the forum, thank you for your post. In answer to your question which I must assume is to do with date formatting in Word;
Word allows for many different types of date format, inside tables and in the main text area.
To format the date within both areas follow these steps; Use the menu command Insert>Date and Time and choose from the different options presented in the dialog box. At this point you can also choose to have the date update automatically each time the document is opened.
I hope that helps, best regards Pete
