Question

The calendar for the year of $2009$ will be the same as that of the year

• A. $2013$
• B. $2014$
• C. $2015$
• D. $2016$

Answer 1

The correct option is C $2015$

$2008$ was a leap year.
A leap year has two odd days.
Suppose year $2008$ starts with Monday.
Then the first day of $2009$ was Wednesday.
Now,
First day of $2010\to$ Thursday
First day of $2011\to$ Friday
First day of $2012\to$ Saturday
Because $2012$ was a leap year,
First day of $2013\to$ Monday
First day of $2014\to$ Tuesday
First day of $2015\to$ Wednesday
Thus, the calendar for the year $2009$ was the same as that of the year $2015.$
