Left handed birthday dates
We have now completed the analysis of the birthday date responses and you can see the results here.
We get a lot of emails about Left Handers Day from Club Members saying that 13th August is their birthday! This got us thinking about whether there is any relationship between being left-handed and the time of year you are born and also whether that would be affected by whether you are in the Northern or Southern hemisphere. For example, if left-handers are more likely to be born in the summer months of June to August in the UK, should we expect more Australian left-handers to be born in those same months or in THEIR summer months of December to February?
We found one study where the researcher claimed a larger than expected number of left-handers were born in November, but only with a very small sample size (33). A larger study by our friend Chris McManus at the University of London (and author of the excellent book Right Hand, Left Hand) came to the conclusion that there was no seasonal trend in births of lefthanders. There is an article about Chris's study here, but he still only had 207 left-handers in total.
Another study concluded that slightly more left-handers than right-handers are born in the five months of March to July, all based on US data, but we cannot find anything looking at data across different countries.
Well, we have a much bigger sample of left-handers than any of these researchers and spread all round the world, so we thought we would do our own little study! Can you help us?
Please fill in the short from here to tell us where you are and your date of birth and we will do some analysis and see what we can come up with.

I am the only left handed member of my family.
I have a female cousin who is also left handed born in April and our father's were brothers.
I don't know of any other members of the wider family that are left handed.

My dob is 15th July 1954
I have a granddaughter also born and resident in the UK who, at the age of 5 is TOTALLY left-handed! Her dob is 22nd October 2017.
Hope this helps!
My mum (26 October) is very right handed. My brother (15 August) is very left handed. My Dad (29 January) & I (7 January) are left handed but use our right hands a lot more than my brother can, eg we use right handed scissors & struggle to use my brothers left handed scissors.
My husband is left handed, too, but both of our daughters are righties.
His parent were both right handed, also.
My birthday is 19th march 1997 & everyone born this date which is 3 people I know are lefties too
My mother, father and sister were all right handed.
My mother, father and sister are all right handed, My husband and our two sons are all right handed.
'lefties'!
We live in Australia and each of we left handers were born during the warmer months from November 4 through to January 5.
My daughter, who died, was right handed like her Mother but my son is also left handed.
*Several of them are/were ambidextrous. Does that count as being lefty, too?
I enjoy your service to the left-handed community of the world. BRAVO! Keep it up!

I am proud of my left-handedness!!!
We had twin sons, identical and one is left handed and the other right handed.
The doctor told us that is another sign of identical twins, they face each other and their writing hand is on the same side. When they grew up, the right handed son had all left handed kids, and the left handed one had all right handed kids. Our daughter, who is right handed married a left handed man and both her kids are left handed. (she says I am the only right one in my family, ha.
So we have had lots of fun with left handed. We have a fun sign: Everyone is born left handed, you become right handed when you first sin. We are still left handed. ha.

One of my bosses was also left-handed and he used to say all lefties are sensitive and artistic - very true!!!
Righties: Dad April, Brother June, Daughter June, Daughter October, Daughter November, Son May, GS June, GD May, GD July, GS January
Lefties: Mom December, Sister April, Sister November, Wife August, Me March, GS August
Mum was born 4th August 1919 in UK and my son was born on 16th July 1980 in Australia. Strangely in the preferred months unlike me born in November :-(

I used my right hand for athletics, pitching baseball, bowling, basketball etc. I kicked football with my left leg.
I found I could learn touse my opposite hand much easier than right handed friends. as far as I can learn I am theonly southpaw on either side of my family.
I don't have a backhand in tennis, but am predominantly right handed for playing sports, and am definitely right eyed. My husband coincidently is a righty, but plays sports left handed!!
I have a right handed brother, and twin sons who are both right handed.
Neither my children, nor my nieces and nephews are lefthanded. Same goes for my 2 great-nieces. It is a lonely experience for me!!
I love meeting other lefties & immediately notice which hand people use. It's so much fun to relate to another leftie.
He was forced to write right-handed in school.
He was a keen cricketer, spin bowler, who could bowl with either hand! Kept the batsmen guessing.
His party trick was to write two letters at the same time... to two different people.
He was artistic as he could draw, paint and sculpt-in-plaster, but I'm afraid he didn't pass that on to me.
My niece Mairin is a leftie, and both my grandsons are lefties.
I was a Xmas present from my dad to my mum,&, 9 months later ,in the spring in the southern hemisphere) I was born!! (2 weeks prem apparently)
My parents & sister are NOT left handed ,
but my dads brother was a lefty.
& my 1st cousin on my mums side is & a few others on her side too!many on the arty farty McCubbin side are apparently!
cheers & good luck with the info you gather,will be interesting to hear what you find?
I have a friend who is the middle child of seven. She is the only lefty born in Nov. She has three kids and only get daughter is a lefty born in April.
I am from a large family - six children - and I am the only leftie. Both my parents have large families as well - a combined total of 24 siblings from each side. Only one uncle, my mother's brother, is left handed. None of my sons are LH and neither are my three grandchildren. Of my fifteen nieces and nephews, only one is LH. Coincidentally, my birthday is in November so for once, according to your survey, I am actually in a majority!!
Neither of my parents are left-handed but...
My paternal Grandmother was left-handed and her
Birthday was 2-10-1910.
We are all from the USA.
My mother's brother born 5.5.16 and his daughter born 23.2.51 both left handed though not my aunt by marriage born 1.2.15.
Is there any research or theories about children born of older parents being more likely to be left handed?
This does seem to be the case for our family.
Has there ever been a study or survey re: snow shoveling handedness?
I also realized that my camera favors right-handed people. Are there any digital cameras out there with the buttons on the left and the lens on the right?
I was born after the world series of 1942. My father said the pitcher for our home team the St. Louis Cardinals won the game. He was a left handed pitcher. His name was Ernie White.
He was not a true left hander. Everything else he did was right handed.
I myself am a true Left Hander. I am the only one in my family who is Left handed...
Ernie White
Like other lefties I notice when people are left handed. There are so many unique qualities to being left handed, right brain thinking for example.
Despite the minor daily inconveniences we all experience, I love being left handed.
I have also wondered about any connection between being left handed and gay. I'm in that category and know that a large proportion of gay people are left handed. That's not to say that all left handers are gay.
My father was right handed born Dec 10, 1919, My mother was Left Handed, born May 6, 1924. One brother of mine is Left handed, born Nov 16, 1951. I "think" that my natural brother from my mother and real father was also left handed, but am not sure, cause he might have been changed in school as I was and doesn't exhibit LFH tendencies. He was born Dec 30, 1947.
I am teakowando player but in football I can play with both of my foots as the same.
I hope to have left-hander children.
I am Aussie and born on 2 Oct 1951.
Neither of my parents are lefties.
My younger brother: 09th October 1996 Vietnam
Any takes on that?
We were very close. He died November 27, 2009.
I was one of two in my family that was born left handed. The other was my Grandpa. He was born May 5th, 1947.
Best bet Is, I was born almost In the middle of the Day, Almost the middle of the week, month, year & decade!!!!
11:55 On Thursday June 12th 1975!!
my son Matteo on 22/07/2004, in Italy, but English father
Two others are ambidextrous and one is right handed.
So many more lefthandedness in the family, mine especially...(it is very large!).
do you want me to list them all?
My wife, born 28/9/47 in England;
My sister, born 20/2/54 in England;
My mother-in-law, born 8/3/13 in England;
My aunt, born 19/4/23 in England;
My grandmother, born 18/5/1888 in England of Jewish parents who had recently migrated from Italy.
There is an obvious bias towards the first half ofthe year in this sample, but I think there is a similar bias among the RH members of the family as well.
I have one child and he is right handed.
I think it is interesting that the twins also have a mirror image of their lense prescriptions for their eye glasses/contact lenses, the same prescription but for the opposite eye. The optometrist always commented on it when they were younger and I took them together to the Dr.
I'm a lefty 13.06.1974
2 out of my 6 children are also lefties
15.12.95
29.07.08
I have two children and one is left handed and the other is right handed. My son's birthday is 12/13.
Both husbands were right handed, I'm left handed, my birthday is 4th March (not telling you which year!)
I don't seem to fit into any of the study categories mentioned and neither does my wife!
On another note, there has been the ongoing debate about leftism being nature or nurture, well we have two children now who are both right handed, we haven't been biased either way, we have allowed our children to decide for themselves, although I'm sure they have had some 'guidance' at school! So it would lead me to believe that if two left handed parents bring up two right handed children then this would edge toward the idea that handedness is a genetic trait the same as hair colour or sexuality....
I'll leave that little bomb shell and let the comments begin :)
I remember my pre elementary teacher asking me, which hand are you?
I don't know what to answer and I saw my book which the pages starts from left then goes to right. Then I told my teacher, I'm left handed! Hahaha silly me
I thought left was first so I choose left as my handedness
Try it? nothing to lose

My wife, now passed away, was right handed but one of my two sons is a leftie, and his was the easier birth and he is more laid back, the same as me!
One other point, I love drawing and painting, my leftie son is an actor as is his partner who is also a leftie, both are good at drawing, coincidence? However, their son appears to be right-handed, he's 3 years old, and we thought that he would have been left-handed because of the gene thing! Hmmm, perhaps they should use a ruler on him!!!

June 18, 1962 here. Only lefty in my family.,
Deb
Both my kids are lefties. Son born Aug 21, 1998, daughter born April 9, 2001.
I am a July birth. I noticed that of the left handers in the team back then, 99% were born in July. My uncle on my father's side and my cousin who are left handed were born in July. That has always intrigued me. When I see a fellow left hander I always try to find their birth month just to see if they are of July birth. Still intrigues me and I am still searching.
Just a thought ; Might have been nice to have had all those who commented of which Country they are from. Could not see a problem with that.
Regards,
Lewis.
I too always notice when people are lefties, especially celebrities in movies!
I am also a geologist and there are a lot of lefties that are geologists!
My boss is also left handed - he was born in the United States - birthdate: 18 Oct 1954.
My daughter is left handed - she was born in the United States - birthdate: 24 Feb 1985.
My boyfriend is left handed - he was born in Canada - birthday: 6 July 1962.
His brother is left handed - he was born in Canada - birthday: 9 January 1956.
His brother's wife is left handed - she was born in Canada - birthday: June 1949.
My father was left handed - he was born in the United States - birthday June (he passed away 30 years ago and I've forgotten the date and year).
I am so left handed - the only thing I could do right handed was dial a telephone! Most people don't remember when telephones had rotary dials!
I LOVE being left handed!
I also went to a catholic school and they tried to switch me to the right. My father went down and told them absolutely not! I notice lefties all the time, like our last three presidents.. I am proud to be a lefty!! and we are the only ones in our right minds!
I also do everything left handed..it feels weird to even think of doing something with my right hand
No one in my immediate family is/was left handed but I had an aunt who used to get hit with a ruler for writing with her left hand. she became ambidexterous (not sure of spelling) and could write with both hands and you couldn't tell the difference.
My sister and my writing is really similar but she is right handed.
Personally, except for the odd thing, that is obviously for right handers (notebooks with coils!) I love being different and being left handed!

I'm the only leftie in the family, but it's early days yet with my grandchildren. At what age does handedness develop? My sister (who knows EVERYTHING about EVERYTHING (she thinks) insists that it's only after about 2 or 3 years - and as her son is a doctor, she MUST be correct...).
My big leftie problem? The availability of golf equipment in-store. I bought a custom-built driver 2 years ago, went to collect it - and found that they had produced a right-handed version! Typical!
I'm a St. Swithin's Day baby (15th July 1954) fyi.
My Dad is also left-handed, his birthday is 19/2/1923, and now, after many years we finally have another special person. My second youngest granddaughter is proving to be left-handed also. Her birthday is 4/1/2011.

On a similar topic, but one you may have covered in the past, I find careers and left-handedness seem to go together. For instance, I'm a retired journalist. We seemed to have a greater than average percentage of lefties in the newsroom at my papers, but hardly any in the printing area. And I needn't point out the number of left-handed actors you see on the screen. Are we lefties more creative?
And just as a matter of interest, I share my birthday with Barry Gibb of Bee Gees fame, who I believe is also left-handed!
11 July, 1949, 12:15am, 6.5#, 19" (not sure on what that would be in the metric system)
my mother 6/ march
my father 12/ feb
my birthday 3/ dec
my brother 19/ march
my uncle 7/ april
my cousin 21/ may
We have no history of anyone in our family being left-handed. We are the only two. My sons and my nephews are all right-handed...as are my five grandchildren.
Just think it's odd that my sister and I who are so close in age both ended up being lefties.
I am probably one of the strange left handers.
I do everything left-handed - except write - I don't recall ever being 'forced' to do so. Shocking hand writing though.
Strangely, having written something that I wish to underline, I have to put down the pen/pencil to pick up the 'ruler (in my right) and underline with my left. Kick/throw a ball, bat, fire a rifle, use tools - all with my left side. Trying to do anything with my right, other than write is absolutely foreign to me. Only relative I am aware of with left tendencies is my second son (ambidextrous) who was born on 31 May 1965 in Darwin Australia. As a cricketer he bowls left and bats left or right - confusing for the opposition!!!
Numbers over the last 70 years to left/right
Does it increase if children are
allowed to be left handed as I was born in 1950
Birthdays are 10/06/87
24/10/94
12/04/97
so we cover the year pretty well!
I am unable to send the data as I got an error - Missing required field 'Country of Birth' I can't fill that field in as it is not visible to me.
Birth months are Feb, Mar, Apr, July, Dec
2 of my granddaughters are left handed and they were born in april and may 2007
my grandson is left handed and he was born in september 2009
and it looks like my other grandson is going to be left handed and he was born in november 2010
In my family growing up me and my brother were the only lefties. I married a rightie and 2 of our 4 kids are lefties 1 boy and 1 out 3 girls.
Just thought that might help in your study, excellent news letter, look forward to the new edition everytime, keep up the good work.
