Leap Day, February $29$, $2000$, occurred on a Sunday. On what day of the week will Leap Day, February $29$, $2020$, occur? 
$\textbf{(A) } \textrm{Tuesday} \qquad \textbf{(B) } \textrm{Wednesday} \qquad \textbf{(C) } \textrm{Thursday} \qquad \textbf{(D) } \textrm{Friday} \qquad \textbf{(E) } \textrm{Saturday}$
There are $365$ days in a year, plus $1$ extra day if there is a Leap Day, which occurs on years that are multiples of $4$ (with a few exceptions that don't affect this problem). 
Therefore, the number of days between Leap Day $2004$ and Leap Day $2020$ is: 
$16 \cdot 365 + 4 \cdot 1 = 5844$
Since the days of the week repeat every $7$ days and $5844 \equiv -1 \bmod{7}$, the day of the week Leap Day $2020$ occurs is the day of the week the day before Leap Day $2004$ occurs, which is $\boxed{\textbf{(E) }\textrm{Saturday}}$.
