On 8th February 2005, it was Tuesday. What was the day of the week on 8th February 2004?

A) Tuesday
B) Monday
C) Sunday
D) Wednesday

8th February 2004 was a Sunday. This follows from the fact that 2004 was a leap year, which adds an extra day to the week difference. Therefore, moving back from Tuesday (8th February 2005) by 2 days results in Sunday.

To determine the day of the week on 8th February 2004, given that 8th February 2005 was a Tuesday, we need to account for the number of days between the two dates.

Find the number of days between the two dates:

2004 was a leap year, containing 366 days. Leap years have an extra day, the 29th of February.
From 8th February 2004 to 8th February 2005 covers exactly one year. However, since 2004 was a leap year, there are 366 days from 8th February 2004 to 8th February 2005.


Calculate the day difference:

In a normal year, there are 365 days, which is 52 weeks and 1 extra day. This means that the same date one year later would be one weekday later.
In a leap year, there are 366 days, which is 52 weeks and 2 extra days. Therefore, the same date one year later will be two weekdays later.


Apply this to our case:

Since 8th February 2004 was in a leap year, we move backward by 2 days from a Tuesday.
If 8th February 2005 was a Tuesday, then:
1 day before Tuesday is Monday
2 days before Tuesday is Sunday





Thus, the 8th February 2004 was a Sunday.
Therefore, the correct choice is C) Sunday.
