06. How To Figure Out What Day Of The Week Falls On What Date.
You might be confused by the picture below, but the math is quite simple (albeit a bit elaborate). You’ll need the codes HERE, which will help you master this.
July has a code of 5.
20th is six because seven goes into 20 twice, which is 14. 20 – 14 = 6.
2069 is two because the leap year code of 2068 is 1, and 2069 is one year after, so that’s 2.
The math can be difficult at first because there are a lot of codes, but it works out incredibly well once you pick it up. Here’s a particular example: January 3, 2014, is a Friday, right? So, January, according to the table, is 6, and we handle days by using multiples of 7. We don’t need to, so it’s just 3 in this case. Next, we need to know the closest leap year, 2012. That has a year code of 1, and 2013 is two years after, so three.We get 6 + 3 + 3 = 12 – 7 = 5! FRIDAY!
