3. Now you can change the text for AM and PM symbols to your desired string. You can also completely remove the AM, PM symbols by removing “tt” from “Time format” text box. Even you can interchange between 12 hour and 24 hour time format by using “h” and “H” respectively.

Click on “Apply” button to apply the changes, then again click on “Apply” button to close the main Regional Settings window. Now the system tray will show your desired text instead of default AM and PM symbols:

4. There is a limitation in this method. You can only type 12 characters in the AM and PM symbol text boxes. What if you want to set longer string? Then you’ll need to edit Registry.

5. Type regedit in RUN dialog box and press Enter. Now go to:

HKEY_CURRENT_USER\Control Panel\International

Now look for “s1159” and “s2359” string values. Both represent AM and PM symbols respectively.

  1. Hello Vishal, Good work yaar. Listen How can I display seconds in windows 7 at bottom right corner of screen where the clock is? 10:52:10 PM. something like that.

  2. Some people prefer to use roman numbers as month symbols (I for Jan, II for Feb… XII for Dec). Is it possible to replace short months names with romans or use some other method to see date as 31 XII 2014?

  3. I know raising the menu to 3 lines will show Date, Day of Week, and Time. I know of TClock 3rd party app can do it all 1 line, but can this be done only from Windows somehow?

  4. Hi. It seems that “s1159” and “s2359” are tied to the fn. of the clock. Is it, then, poss. to put there ddd or something else that will display the name of the day and change according to the fn. of the clock?
