Thus, it has 1 odd day only.
The day on 8th April, 2005 will be 1 day beyond the day on 8th April, 2004.
Given that, 8th March, 2005 is Monday.
8th March, 2004 is Sunday (1 day before to 8th March, 2005).

Answer:C
Explanation:
We shall find the day on 1st May, 2001.
1st May, 2001 = (2000 years + Period from 1.1.2001 to 1.5.2001)
Odd days in 1600 years = 0
Odd days in 400 years = 0
Jan. Feb. March April May
(31 + 28 + 31 + 30 + 1) = 121 days 2 odd days.
Total number of odd days = (0 + 0 + 2) = 2
On 1st May, 2001 it was Tuesday.
In May, 2001 Thursday falls on 3th, 10th, 17th and 24th, 31st.
