6. Bagaimana Nak Tahu Hari Dari Tarikh Yang Diberi
You might be confused looking at the picture below, but the math is actually quite simple (albeit a bit elaborate). You’ll need the codes HERE, which will help you master this.
July simply has a code of 5.
20th is 6 because 7 goes into 20 twice, which is 14. 20 – 14 = 6.
2069 is 2 because the leap year code of 2068 is 1 and 2069 is 1 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 separate 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 actually just 3 in this case. Next we need to know the closest leap year, which was 2012. That has a year code of 1 and 2013 is 2 years after, so 3 again.
We get 6 + 3 + 3 = 12 – 7 = 5! FRIDAY!
