No fucking way leap day is so damn high, not only is this ugly, it has to be outright wrong!


ShelZuuz

Why would the the average number of people born on leap day be significantly different than on any other day?


Schuben

Because it only happens once every 4 years. Assuming a completely even distribution of births per day you'd expect Feb 29th to have 25% of the births as the other dates over a time span of a multiple of 4 years. If this were measuring only 1 year that happened to be a leap year you'd expect it to be just about equal other than external factors such as people wanting or not wanting their child to be born on a leap day.


ShelZuuz

I must have missed the part of the spreadsheet that they said: “as averaged over 4 years”. I foolishly assumed they just count the number of births each day and ordered it.


MeanderingMonotreme

if they did that then the chart only applies to the specific year they chose to get data for, and the title is actively misleading in not giving that information. (The chart is still problematic as an average for not giving the date range, but I'd classify that as a "bad chart" as opposed to "misinformation")


daedone

Ok, well 3/4 of any year you pick has 0 Feb 29ths


ShelZuuz

Divide the total number of birthdays that occur on that day by the number of times that the day occurs. Nobody would even give this a second thought of how to do this if the chart showed this as birthdays per day of the week (Mon,Tue,Wed,Thu,Fri,Sat,Sun) - even though a year doesn't have the same number of those days either. You just count total birthdays on a day divided by the number of times that day occur over whatever period you choose. But for some reason February 29th is magical and breaks down all human reasoning.


daedone

But if you did it by week, you would still have to specify 365 vs 366 days. And at least 1 of the 7 will have a slight edge due to extra days because 364 divides by 7 evenly...which is why we have a leap year in the first place. So now you're back to specifing a time range (how many years of data) to show a "proper" picture


Quartia

Jan 20 can't possibly be least, where is Feb 29?


FreeComplex

Maybe it’s just tying to rank dates by number of births on average. As in, the number of children born on February 29th isn’t 1/4 that on the surrounding days. Although I still think the data looks wrong. Would expect something more like this: https://thedailyviz.com/2016/09/17/how-common-is-your-birthday-dailyviz/ Although that is just for the United States from 1994-2014, not sure what the picture is supposed to be for.


Quartia

This looks so much more logical. There are clear trends (summer births most common, fewer around major holidays, and spike on Valentine's day) but also a reasonable level of randomness. Meanwhile the image has January, then June, then March, then November at the top, while the last is also a January date. It is totally random. Probably one of those "trying to get people to share their identifying data" scams.

bonafidebob

That’s July 4th, a major US holiday. I suspect many parents induce or try to delay or maybe even change the birth certificate to avoid a 4th of July or 25th of December birthday.


simiansecurities

Fewer doctors on staff on holidays -> fewer induced births


lorarc

Also probably "Let's get over with it today because tomorrow we're off".


nepcwtch

so i at least ping the ppl in this comment thread who put some real thought into it, i thought id comment and say i found the image source and made a comment outside the thread that clarifies. basically its not unlike astrology, its a japanese birthday luck chart for the year 2020 (jan 20 got a birthday in retrograde...) and while the blog post probably isnt phishing, the reposts probably are


Protean_Protein

Shouldn’t the spike be 9 months after Valentine’s Day? November 14?


Quartia

What makes everyone think the body counts out *exactly* 9 months, and delivers on that date?


Protean_Protein

The point was more that if Valentine’s Day is significantly peak Marvin Gaye / Barry White day, we should expect days between ~38-41 weeks from then to be among the most common birthdays.


oobananatuna

The spike on Valentine's day is very odd to me, especially as it's so extreme compared to the surrounding 3 months. I understand the low numbers on major holidays, as there will be fewer induced births those days, and you can see corresponding spikes before and after, but are people really so keen to be induced on Valentine's day?

oobananatuna

The raw numbers are in the link - the top day actually has double the number of births of the bottom day!


[deleted]

As someone born on February 29th… I do not believe this. I’ve never met another Leap Baby in person and have only had 2 people ever tell me they also know someone born on Leap Day. But what do I know, I’m only 6. 🐸 Also my birth certificate & driver’s license both list my birthdate as 02/29/1996.


samnoack

56 apparently


Quartia

Then this is obviously not real data and is just randomized.


cheeze_whizard

To possibly add some credit to this, 40 weeks before Jan 20 is April 15, aka Tax Day.


Quartia

Only a tiny minority of pregnancies last exactly 40 weeks. Anywhere between 38 and 41 is normal. So most trends in birth dates happen only on the month level and not the individual day level.


ososalsosal

56. I call bullshit


Drok00

IIRC Feb 29th isnt what is listed on a birth certificate, they will change it to the 28th or the 1st.


Quartia

If that were true there would be 365 not 366. Check out number 56. This data is obviously fake.


nirad

My aunt has Feb 29 listed, but she wasn't born in the US. She's much younger than her three kids.


[deleted]

I was born in the US - my birth certificate and driver license both list the 29th.


tacops777

56th!

This is the epitome of ugly data Wrong and hard to read


indiequick

I found myself at 363.


RegentYeti

Happy 10 days since your birthday.


dragotha

According to whom? No source, no years, no demographic? This truly belongs in this sub.


nepcwtch

this is a lucky birthday chart compiled from [a japanese divination blog?](https://medigaku.com/2020-123/) for 2020, not at all a common birthday chart. i cant help but wonder however if the recirculation of these charts on social media sites is a phishing scam... its certainly not the ugliest data, but the fact that its been turned into an image makes it rough if you werent born on like, january 12th.


tjhcreative

Someone in another sub mentioned this being a Japanese list as well. I found it on Facebook as a simple common birthday list. Not sure about the phishing intension onFacebook, but I certainly wouldn’t be surprised. Certainly aren’t striking gold with it though - Birthdays aren’t tough to find.


Quartia

>the recirculation of these charts on social media sites is a phishing scam Of course it is exactly this.


8_Miles_8

A proper chart with a 9-month shift would be a good gauge if when people frequently have sex, though the data may be muddled by the fact that it does more likely to be couples without contraception, etc.


abirdbrain

mid-late Nov needs to be way higher up on this list. the amount of valentine’s day-conceived people in know (including myself) is so much higher than this claims


DeepBlueNoSpace

Jan 12th gang where u at??

Number 1 again, bitches!


MemeWhomstIsViet

pretty sure this is one of the years of the japanese birthday luck things. Like it’s arranged in an ugly way regardless but it’s not based on commonness


ShadowShedinja

Rank: 1st, 2nd, 3rd, then 4, 5, 6...


RegentYeti

Hmm. My youngest child and I both fall into the 110s range, my 6-year-old twins are in the 150s, and my wife is waaay down in the 350s.


Spespety

Any May 13rs here


ogjsb

Bluecat0817

If we scale this 9 months back we can find the days where people have the most sex


noodlegod47

If they were at least color coded..


FrostyFreeze_

Shout out to my birthday being the least common... yet somehow 3 of my friends share the same birthday


JonOsterman59

So Jun 7 is 2nd and un 4 is 364th? Hmmmmmmm

Guess the mods will remove it then.
