If you repeat a lie often enough, it becomes the truth. – Misattributed to Joseph Goebbels
(See what I did there?)
And that is the truth of the matter. People will believe anything as long as you keep on repeating it to them. Maybe I am tired of that and so I want to say it here. Before my kids get to learn of the lie(s) and spread it around the world.
- Month X has 5 Sundays. This happens once in every 823 years.
Yes, the first time you heard of it, you were wowed. Your eyes popped out. You believed you were part of history. You were the type that were stupid enough to forward the message that if it won’t get around to 5 people you will get good bad luck in the next twenty minutes. You knew that this was an impossibility but you still did it.
But the one for months with 5 Sundays in 823 years is true. It has been tested and it is actually known to be true.
Well, son. Grab a pencil, some A4 paper and a calculator and I take you to class for a minute. We say that an year has 52 weeks, 12 months and a month has 4 weeks. Right or wrong?
Right. Good, simple mathematics will tell you that 12 months multiplied by 4 weeks per month will give you 48 weeks. Those are then the number of weeks that we will have in an year if we were to partially take the above definition. That then leaves us with 4 weeks that are unaccounted for. Let us leave that pending and we go to the next thing; days in a month.
The number of days in a month vary from a minimum of 28 to a maximum of 31. But a week has 7 days. And if a month has 4 weeks, there will be at least 11 months in an year that have days that are unaccounted for. Do they fall in an imaginary week or what? That is where the 5th week comes in. If I have lost you so far, go back up and then leave a comment if you still don’t understand.
That then means that at least 4 months in any calendar year will have ’5 weeks’. And if a week starts on Sunday and ends on Monday, how many Sundays will we then have? 5 Sundays in any month.
By the same workings although with careful substitutions for days with weeks and all those other things, a leap year has 5 months that have 5 Sundays each.
And for any month to have the 5 Sundays, that means that month has to come around once in every 823 years (if we take that the months happen just once). If we take it that they require after every other 11 months, then we have an even smaller probability of about once in every 69 years. That is two and a half generations.
Next time you write that nonsense on Facebook, Twitter or G+, get your head checked. And as you move from the left to the right of the social networks list, get more psychiatrists.
