Born February 29 and left-handed.


Recommended Posts

there is always a bit of a spike around the end of January until the middle of February in populations that include a lot of Chinese people - but 29th of February is just outside the range of possible dates for Chinese New Year's Day proper.

 

whilst nobody intends to have a baby for leap day, plenty want to have a baby to co-incide with Chinese New Year and the two dates can co-incide.

Hence when taking global matters into consideration, makes this question even more definitively unanswerable :hihi:

A cousin of mine was born on 29th Feb,  also my nephews daughter was born on 29th Feb. Not left handed as far as I know.

 

In my immediate family we have  6 left handers :

Son.

Daughter in Law.

Son in Law.

2 x  Grandsons.

My Sister.

 

Out of these,  3 are ambidextrous because although they write with their left hands, they use tools etc right handed ( probably out of necessity )

here is how I would attempt to answer this. There is one leap day in every 1461 days.

 

roughly 11% of the world is left-handed. So let's just say there's a 10% chance of somebody born being left-handed.

 

it's difficult to calculate precisely, because the birth rate is variable. More people are born at particular times of the year than others.

 

but if you assume the birthrate is constant (i.e. the same four years ago as it is now, or the same at the end of February as it is at the beginning of December, which it is not) then somebody has a 1 in 1461 chance of being born on a leap day.

 

then it's roughly 10 times that that will be left-handed.

 

therefore the rough odds of somebody being born on a leap day and left handed are around 1 in 14600.

My brain hurts so much I might have to start smoking again with one of those right handed cigars even though I’m left handed and born in January 😀
