The calendar of year 1939 is same as which year?

  • A.1943
  • B.1964
  • C.1950
  • D.1956

Answer: C

1939 is an ordinary year. Counting odd days forward until they total a multiple of seven:

\[ 1939:1,\ 1940:2,\ 1941:1,\ 1942:1,\ 1943:1,\ 1944:2,\ 1945:1,\ 1946:1,\ 1947:1,\ 1948:2,\ 1949:1 \]

\[ \text{total} = 14 \quad\Longrightarrow\quad 0 \text{ odd days} \]

So 1939's calendar repeats in 1950 - the usual 11-year gap for an ordinary year with three leap years in between.
