Here is a list of some fact about birthdays you probably don't know:

1. Before the 19th century, dates of birth were not officially noted, although baptisms occasionally were. England began keeping parish records of births, deaths and marriages in 1538 but this wasn’t implemented for the entire population until the Registration Act of 1836. The first British census in 1801 didn’t record age, and it wasn’t introduced as a question until 1831 - even then it wasn’t mandatory to answer. It wasn’t until the 1851 census that people had to record their precise ages.

2. Birthday Paradox
If there are 23 people in a room there is a 50-50 chance that two of them will share a birthday. This is known as the birthday paradox, because it appears there are only 22 possible pairs and therefore a low chance of a match. In fact, because every guest could match with every other guest, there are 253 possible combinations (1+2+3+4… up to 22) and the probability of finding a successful one is 50.048%. If you are confused by that then try view it this way: [If you have a list of 23 people, comparing the birthday of the first person on the list to the others allows 22 chances for a matching birthday, the second person on the list to the others allows 21 chances for a matching birthday - in fact the 'second' person also has total 22 chances of matching birthday with the others but his/her chance of matching birthday with the 'first' person, one chance, has already been counted with the first person's 22 chances and shall not be duplicated, third person has 20 chances, and so on. Hence total chances amounts to 253]. The probability reaches 100% when the number of people reaches 367 (since there are 366 possible birthdays, including February 29). However, 99.9% probability is reached with just 70 people. These conclusions include the assumption that each day of the year (except February 29) is equally probable for a birthday. In fact you don't need bother about this if you aint a statistician.

3. Queen's Birthday
The Queen’s actual birthday is April 21 but she celebrates her official birthday on a suitable Saturday in June (the Government chooses which one). One of the reasons is to ensure good weather for the Trooping the Colour ceremony, held to mark the monarch’s birthday since 1748. The Queen has attended all the ceremonies during her reign apart from in 1955, when the parade was cancelled due to a rail strike.

4. Happy Birthday Song
The “Happy Birthday” song originated in 1893 when teacher Mildred Hall thought of the
tune. Her sister Patty added words and they christened the piece Good Morning to All. It was intended to be sung as children entered the classroom but was switched to be sung to the teacher, and became Good Morning to You. As the song grew in popularity, it was sung outside schools and became Happy Birthday to You. The song is protected under copyright until at least 2030.

5. Cards and Present
Britons send more than 300million birthday cards a year. Cards that play a song when you open them use more computing power than was used to send man to the moon. In the 19th and early 20th centuries, a popular 21st birthday present was to have all your teeth removed and replaced with a set of dentures – the idea was it would prevent the expense of dental treatment later in life. Shirley Temple received 135,000 presents for her eighth
birthday.

6. Birthday as count-up and count-down timer
Each time you celebrate +1year on earth you are as well celebrating -1year to the grave. So birthdays counts down in same manner as it counts up.

fr3do: Copy and paste from a British site

Lol! I don't do copy and paste. That's why i used reference instead of source. I made reference of the site but didn't quote them verbatim. In fact mine has more details in some sections and even an addition of what is not in the site or any other site. So bro, go back to the site and compare

Swear say U neva copy and Paste before...Hu is innocent of that...

Very cul...Stay Connected

very nice.very nice.very nice.

Nice piece... But I think the idea of a countdown to the grave is a little out of place. Life has no definite span, so you can't countdown to the unknown

Life has a definite span,just that man does not know it.

harev16: Nice piece... But I think the idea of a countdown to the grave is a little out of place. Life has no definite span, so you can't countdown to the unknown

since life has no definite span, why are you counting your age to the unknown? Or do you know your final age? Hear the guy above me.

KillerBeauty: I learn something new everyday

Yeah baby thats right, as you're going to learn am your new bf

But that queen's convenient birthday celebration though, that sounds dope....

Number 6 Is A Real Fact...

Let me Add,

The most common birth date of the year is 5th of October which falls 9 months after the New Year’s Eve.

29th February comes once every 4 years, it’s the least common birth date.

No 2... I don't believe.



It took me 25 pages to see someone a day apart my birthday in a birthday match thread here on NL.

fairheven:
Life has a definite span,just that man does not know it.

There may be a definite span assuming everything takes a natural course but an accident or unprecedented events can terminate Life at any point in time so will the countdown run instantaneously to zero in a matter of seconds?

chuxyz: since life has no definite span, why are you counting your age to the unknown? Or do you know your final age? Hear the guy above me.

That's why you can only count up from the day you were born, because you know the day you were born.

Who knows if the accident is part of the span,every day u wake,u are taking a step closer to ur grave,whether young or old

something like??

Em... Number 2... What's the basis for saying that having 23 people (253 possible combinations) would give an approximate 50% chance of matching birthdays? They only explained a simple 23nCr2 and jumped to a 50% solution.

How did they arrive at that conclusion, knowing that for each combination, we have a (4/1461) probability of same birthday?

Someone explain biko

Edited: ok, I understand now.

harev16: That's why you can only count up from the day you were born, because you know the day you were born.

So as you are counting up are you not getting older? If you are getting older are you not getting closer to the grave. That means the time to the grave is shortening(or counting down). Thank you
