If 30th January 2003 was Thursday, what was the day of 2nd March 2003?

Sunday

The correct answer is Option (3) → Sunday

Given: 30th January 2003 was a Thursday.

Number of days in February 2003 = 28 (2003 is not a leap year)

Days from 30th January to 2nd March:

• 30th Jan to 31st Jan = 1 day

• Full February = 28 days

• 1st March + 2nd March = 2 days

Total = $1 + 28 + 2 = 31$ days

Now, divide 31 by 7: $31 \mod 7 = 3$

So, the day advances by 3 days from Thursday:

• Thursday → Friday → Saturday → Sunday
