Hi prasad,

Excel uses the system clock to determine the default year. You have at least four options:
1. Wait till next year,
2. Change the system year to 2012 now,
3. Install a user-defined function to increment the year (this requires vba coding),
4. Enter the required year instead of relying on the default.
