Dates and Times

(Insert > Field)
On the left select Date and Time
On the right pick Date
At the bottom fill out the field so it looks like this:
DATE \@ "h:mm:ss am/pm on MMMM d, YYYY"

Click Insert and the {date} field will be placed in your document
What you are looking at is the result of the {date} field - the text Word puts together as a result of the commands it finds in the field you put in the document.

Those characters are not really in your document. To see what is really there select (Tools > Options)(View, Field Codes)
