title: What is the easiest algorithm to find the day of week of day zero of a given year?
body: <p>I am trying to figure out what the day of the week of day zero (January 1st) of a given year.</p>
  
  <p>So far I have looked at the Wikipedia page '<a href="http://en.wikipedia.org/wiki/Calculating_the_day_of_the_week" rel="noreferrer">Calculating the day of the week</a>' but I was wondering if there is an easiest algorithm if you're just trying to find day zero.</p>
