How do I get my Casio G-Shock/MTG watch to read the day and the date?

Go to casio.com. Go to the "Support" drop down menu and select "Manuals". Click on the "Watch Manuals Archive" link under Watches and make sure you "Accept" the Terms and Conditions of Use. Enter the module number located on the back of your watch casing. This should be a 4 digit number. You should find a .pdf copy of your owner's manual that you can print or download. I personally own a Casio G-Shock similar to yours, but with all watches, the features and functions are not the same. Your owner's manual will give you the definitive answers you need. I hope this helps you.
