Customize calendar of Windows Vista

Can i change the type of the calendar that windows vista uses. If yes then how? Have i need to install multiple calenders for that or windows vista have multiple inbuilt calenders. Thanks for any answer

Here is the answer from Microsoft website:

When you choose a locale for the format of the date, time, currency, and measurements, Windows automatically changes the calendar to match your locale choice. However, some regions support multiple calendar types, and you might want to choose a type different from the one Windows selects.

1. Open Regional and Language Options by clicking the Start button Picture of the Start button, clicking Control Panel, clicking Clock, Language, and Region, and then clicking Regional and Language Options.
   
   
2. Click the Formats tab, and then click Customize this format.
   
   
3. Click the Date tab.
   
   
4. Under Calendar, in the Calendar type list, select a calendar type.

Note The Calendar type list is visible only if there are multiple calendar types available for the locale you select.

You can view your calendar by day, work week, week, or month.

• Click the View menu, and then click the view you want. A check mark appears next to the view you select.

You can also create new calendar :

1. Click the File menu, and then click New Calendar.
   
   
2. In the New Calendar box, type the name you want for the calendar, and then press ENTER.
   
   
3. To choose the color of your appointments, in the Details pane, click Color, and then click the color you want.
