Now it gets a bit more complicated, but don\'t worry: We break it down into small pieces and learn step by step.
<h2> division into century and year</h2>
Let\'s take the year 2013 as an example: In the following we will name the front two digits, "20", the century and the back two digits, "13", the year.
<h2>The year code</h2>
TL;DR: the formula is: (YY + (YY div 4)) mod 7
<ol>
<li> dividing the year by 4 and ignoring the rest: 13 div 4 = (<b>3</b>*4 + 1) div 4 = 3</li>
<li>Totalize the last result with the year: 13 + <b>3</b> = 16</li>
<li> Divide the result by 7 and select the rest: 16 mod 7 = (2*7 + <b>2</b>) mod 7 = 2</li>
</ol>
The year code for 13 is 2.
