July 2011 has 5 Fridays, 5 Saturdays and 5 Sundays.
So let me jump on the table and dance on one leg with joy!
Because I am told by many people that for some obscure reason, this wonderful event happens only once in 823 years!
To burst the bubble right away, March 2013 also has 5 Fridays, 5 Saturdays and 5 Sundays!
Don’t believe me? Just click the time/calendar on the right hand bottom of your computer screen and check out March 2013.
Also, 5 Fri-Sat-Sundays would have hit you roughly that many times as many birthdays you have celebrated on this planet.
Don’t believe me again?
Every year has 7 months that have 3 days which come 5 times in that particular month.
(If a month has 31 days, then every day is repeated 4 times by the 28th of the month.
So 29th, 30th and 31st are extra or “5th” days.
Seven months have 31 days: January, March, May, July, August, October & December)
The chance that those 3 days are Friday, Saturday and Sunday is exactly 1/7th of that, which works out to be once a year!
(If you pick 3 days randomly from 7 days a week, then there are many permutations and combinations.
However, since the days only come in sequence, there are only 7 possible combinations: Sun-Mon-Tue, Mon-Tue-Wed, Tue-Wed-Thu, Wed-Thu-Fri, Thu-Fri-Sat, Fri-Sat-Sun & Sat-Sun-Mon)
Now this event may be skipped in some year and may happen twice in another since 364 days form 52 weeks and the extra 1-2 days shift the day-date matchings randomly.
Also, in 823 years, 3 days coming 5 times in a month will happen a whopping 5761 times!
A simple thumb rule to check on the calendar…
Any 31-day month on which Friday falls on the 29th will have 5 Fridays, 5 Saturdays and 5 Sundays.
Now the person who started this might argue that what he meant to say was that July being such a month will happen once in 823 years!
To answer that, in July 2016, the phenomenon will be repeated.
And you thought that you could say TGIF followed by a same-month weekend five times in a month only once every 823 years!
Call it a “5TGIF-Weekend Month” (5TWM or Fitwem) and it comes regularly 0, 1 or 2 times a year depending on the year.
But anyway, Internet virals ki Jai Ho!!!
Any Falsehood repeated 10 million times by a million people over thousands of networking and email service sites just has to be True!
