Explanation

According to the question,
30th January, 2003=Thursday
So, 6th February , 2003=Thursday
13th February, 2003=Thursday
20th February, 2003 =Thursday.
27th February , 2003=Thursday
[`:.` Every 7th day will be the same day countwise]
So, 2nd March , 2003=Thursday `+3` days =Sunday
[`:.` In an ordinary year, February =28 days]
Another method :
`:.` 30th January, 2003 =Thursday.
So, number of odd days in January 2003=1
Number of odd days in February 2003=28
`=28//7=0` odd days
Number of odd days in March 2003=2 odd days
So, total number of odd days `=1+0+2`
=3 odd days
So, 2nd March, 2003=Thursday+3=Sunday.
