Don't mess about with integers - use a DateTime value instead:

C#

DateTime today = DateTime.Now.Date;
DateTime tomorrow = today.AddDays(1);

You can then use tomorrow.Day and so forth.

You haven't mentioned any exception!

Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Source Error:

Line 42: int year = System.DateTime.Now.Date.Year;
Line 43: int DayTommorow = day+2;

exception only for " ddlDay.Items.FindByValue(DayTommorow.ToString()).Selected = true;" this line

First off, if I suggest code, then reporting the problem based on the older, not-working code is:
a) a bit rude
b) a bit pointless.
The exception is nothing to do with the date: it is because you are trying to use a control that doesn't exist:
FindByValue is returning null because it can't find a matching control - then you try to access a property of a null value, and it throws an exception.

You need to sort out why FindByValue does not find the control you think is there...
