Hi Harry,

Your Module number is 2271.

2. Press button D (lower left) to move flashing in the following sequence to change other setting:
Seconds >> Hour >> Minutes >> 12/24 Hour Format >> Year >> Month >> Day >> (Then back to Seconds)
3. While a setting is flashing, use E (+) (bottom right) and B (-) (top right) to change it.
Note: When in the 12/24 Hour Mode, use E and B to toggle between 12-Hour and 24-Hour Mode.

mcdevito75 here, Many Casio Watch Models out there, I'll bet however your Casio is displaying say 1 AM rather than 1 PM as it should if the time is indeed PM after 12 noon, if so, this is why the date is changeing at 12 PM rather than, 12 AM simply re-set your casio and make sure the time of day is set at PM for time after 12 noon and AM for time anywhere before 12 NOON. Also, as you set your Casio, look for anything that may give the hint of Military time, this may be revilled as 12 hours or 24 hours, if you have anything like this, make sure it's set for 24 hours. If you have additional problems, visit a small watch repair shop in your area. Again there are many, many Casio models out there and without your watch with me it's difficult to be more accurate.

On the Casio 2747 you can easily change between 12-hour and 24-hour (i.e. Military time)... Follow these steps:

1. Make sure you are in Timekeeping Mode (i.e. digital display shows date at the bottom).
2. Press the "D" button (i.e. bottom-right button) to toggle between 12-hour and 24-hour timekeeping.

Note: 12-hour timekeeping mode will display an "A" or "P" for AM and PM.
