What was the day of the week on 16th July 1776?

\(\frac{Date + Month\;code + Century\;code + Century\;upper\;year + Quotient\;of\;\frac{upper\;year}{4}}{7}\) 

\(\frac{16 +6 +4 + 76 + 19}{7}\) = \(\frac{121}{7}\) = Remainder 2

In case of Leap Year the code for January and February is reduced by 1 But here july is given thats why there is no change in remainder code.
