Question

The number of days from 31 October 2011 to 31 October 2012 including both the days is

• A. 365
• B. 368
• C. 366
• D. 367

Answer 1

Answer:

D. 367

1. Leap Year Check: The year 2012 is divisible by 4, so it is a leap year and contains 366 days (due to the inclusion of February 29th, 2012).

2. Time Difference: The time difference between the two dates (31 October 2011 to 31 October 2012) is the number of days in that leap year, which is $\mathbf{366}$ days.

$\text{Difference} = 31 \text{ Oct } 2012 - 31 \text{ Oct } 2011 = 366 \text{ days}$

3. Inclusive Count: Since the question asks to include both the start and end days, we add 1 to the time difference:

$\text{Total Days} = (\text{Difference in Days}) + 1$

$\text{Total Days} = 366 + 1 = 367$

Alternatively, you can think of it as the 366 days of the leap year period (1 November 2011 to 31 October 2012) plus the starting day (31 October 2011).

$366 \text{ days} + 1 \text{ day} = 367 \text{ days}$
