How To Be A Human Calendar (Anyone Can Learn This)

I explain how to calculate the day of the week for any calendar date in history (works only with the modern calendar system). You can do this trick in your head, but it will take some practice (maybe an hour or two). Easily impresses people.
*NOTE* IF YOU ARE WORKING WITH A LEAP YEAR, AND THE MONTH IS JANUARY OR FEBRUARY, THEN SUBTRACT 1 FROM YOUR FINAL ANSWER**

I swear this Guy Looks the Same like Formula 1 driver Sebastian Vettel....

@Senator679 I never heard of the guy until I looked up pictures of him after I saw your comment. He is like a less-Irish version of me that makes more money and is a better driver.

1)How much free time do you have? 2) How much time did it take to come with it and... Most importantly...3) What were you smoking throughout the process?

@GRigori0s10

1) Not that much free time. I learned how to do this trick 4 years ago when I did have a large amount of free time.

2) I did not come up with this, I stumbled upon a webpage a while ago that showed you how to do this, but I do not think the website exists anymore.

3) Absolutely nothing. It would be incredibly difficult to explain this trick if I had been smoking something.

Did you give this a try? It is actually very easy once you do it a few dozen times.

Wow, I did this back in 2000, and used January 1, 2000 (a Saturday) as the starting point : )

@Tim8242 I was talking about what were you smoking when you came up with this... But its not yours. Cool though, and nicely explained!
