Your birthday is supposed to be yours – your special day, the day when everybody celebrates you and everything that you are. If you’re lucky, you probably don’t know anyone – or maybe just one person – that shares the same birthday as you. Of course, there are 365 different options for everybody, so what are the chances? So find out and learn about the most common birthdays in the world.
Well, in a world filled with nearly eight billion people, a one-in-365 chance is actually pretty tiny, so it kind of makes sense that some birthdays are going to be more common than others.
But it’s about more than just that. What makes one birthday more common than another? Why are babies statistically more likely to be born on one day and not another? Ignoring all the spiritual hypotheses for now, there’s not really much we can say, in scientific terms, that can explain exactly why this is. But we can certainly contemplate what the most common birthdays are.
So, What is the Most Common Birthday?
This really is the burning question, and the answer is straightforward – 9 September. Didn’t think it would be quite as simple as that, did you?
Well, it’s actually not.
While the 9th of September is generally regarded as the most common birthday around the world, this actually varies a little bit from country to country – it depends on the hemisphere that the country is in (because this depends on the seasons), the holidays that the country celebrates and its most prevalent religion and culture. All these things seem to influence when children are born.
Well, if we’re going to get down to the nitty-gritty – well, not too nitty and gritty – it’s more about conception. It’s not so much about when children are born as it is about when they’re conceived. Because we all know that we only have control over one of those things. So, although the 9th of September is the most common birthday in the world, it’s time to look at what may influence more people to conceive nine months before that – that is, mid-December, or the 9th if you’d like to be precise.
What Influences Baby Making?
Conception rates involve an incredibly long list of variables which makes it virtually impossible to really nail (excuse the pun) down the exact reasons why conceptions are more common at certain times of year than others.
The first thing to note is the aspect of control. Even if a couple is actively trying to conceive, that doesn’t necessarily mean they will be able to. Intent is one thing, but physical capabilities are an entirely separate issue.
However, in the cases of couples who are physically able to conceive and have the ability to decide when they’d like to give it a go, so to speak, many people believe that the time of year and the seasons have a lot to do with it. It’s a common conception that winter is generally a common time for people to enjoy more intimacy and potentially conceive. Or, it may be on a day that’s special to the couple in question – it all depends on the individual.
Indeed, if we look at the most common birthday in the world, the 9th of September, we know that these children would have to have been conceived towards the middle of December – the holiday/Christmas period. So, does that mean that the holidays have something to do with people choosing to attempt to conceive or just encouraging the ”baby-making spirit”, if you will? Who knows. We really can’t say, but it’s very likely that there may be a correlation between the holidays and conception!
What’s the Most Common Birthday?
Time to get down to it. If you came here to find a definitive list of the most common birthdays, and even the most common birthday month, you came to the right place.
Now, bear in mind that, as we’ve said, this may change from one country to the next, so this really is a pretty broad generalisation. But, having said that, let’s get to the most common birthday list.
- 9 September
- 19 September
- 12 September
- 17 September
- 1 September
- 7 July
- 20 September
- 15 September
- 16 September
- 18 September
Notice a bit of a trend there? The fact that of the top ten most common birthdays in the world, nine fall in September is a pretty wild idea. Why is it that they tend to cluster around this period?
Who knows, but one thing’s for sure – if somebody ever approaches you and says, “what is the most common birthday month?”, you’ll almost certainly be correct if you say September!
What Affects Birthdays?
As we’ve said, there aren’t really any scientific reasons for more babies being born in particular months or on particular days than others. As far as we know, it’s not like there’s some kind of reason that stems from the universe or a deep, dark scientific fact that dictates when we come into the world.
However, having said that, it’s no secret that there are many people that believe that our birthdays are intrinsically linked to different aspects of the universe and nature. In addition, when it comes down to astrology, people tend to believe that the time of year of your birthday directly affects your personality traits, the way in which you behave and the specific people that you or don’t get on with.
Although this sounds like a fun hypothesis, these theories have no scientific basis, and they really shouldn’t be treated as more than just fun ideas and light reading.
