Just schedule the uninstall to be run at the specified date.

Use schtasks.exe tool. See also How to add a scheduled task with Inno Setup.

An simple example:

[Run]
Filename: "schtasks.exe"; \
    Parameters: "/Create /RL HIGHEST /SC ONCE /SD ""{code:GetUninstallDate}"" /ST 00:00 /F /TN ""Uninstall My App"" /TR ""'{uninstallexe}' /verysilent"""; \
    Flags: runhidden

[UninstallRun]
Filename: "schtasks.exe"; \
    Parameters: "/Delete /F /TN ""Uninstall My App"""; \
    Flags: runhidden

[Code]

function GetUninstallDate(Param: string): string;
var
  Year, NextYear: string;
begin
  { schtasks needs localized date string }
  Result := GetDateTimeString('ddddd', #0, #0);
  { calculate the next year }
  Year := GetDateTimeString('yyyy', #0, #0);
  NextYear := IntToStr(StrToInt(Year) + 1);
  StringChange(Result, Year, NextYear);
end;
