    1. 2003
    2. 2006

According to question , we know that
Starting with 2000, count for number of odd days in successive years till the sum is divisible by 7.
2000 + 2001 + 2002 + 2003 + 2004 = 2 + 1 + 1 +1 + 2 = 7 odd days
∴ Number of odd days up to 2004 = 0 odd day
Hence , Calendar for 2000 will serve for 2005 also.
