How popular is your birthday?

Now, we’re not talking about how many guests will RSVP to your birthday bash invitiations when the topic of popularity comes up. We’re actually talking about how common your birthday is, ie how many people you share your special day with. And ultimately, why mums are seemingly more proficient at popping out babies on certain days of the year!

Most popular

In New Zealand, figures from Statistics New Zealand show that in the last 35 years, the most popular birthday is 30 September. If your birthday falls on this date, you share your birthday with about 14,200 people in New Zealand.

The 10 most common birthdays all occur between 22 September and 1 October. So counting back, the most popular time of year for conceiving a baby is definitely around Christmas, New Year and those relaxed, summer holidays.

In other countries, similar patterns emerge. In the UK, the most popular day is 26 September, whle in the USA it is slightly earlier at 16 September.

Are you more unique?

The date with the least amount of birthdays (not including the four-yearly 29th of February) is Christmas Day, 25 December – after all, no one wants to share their birthday with the biggest present gifting day of the year if they have a choice! Public holidays tend to also have low birth rates, presumably due to the lack of planned births, ie elective c-sections and inducements at a time when less staff are available at hospitals and birthing centres.

    It is interesting how the birthdays revolve around events such as Christmas rather than the different seasons when comparing the popularity with countries overseas.

    Interesting. 313 out of 336….I guess most birthdays overlap anyway…sharing with 13k + others in NZ makes you a realise how big our world really is.

    Ranked 135 how interesting was this. I never even gave it much of a though before, although most people who are born on my birthday I think are pretty awesome. So it may not be ranked high but I think it is a pretty cool day to be born 🙂

    When I was younger I used to joke about being 9 months after New Years! I’m oct 1st, so the 7th most popular day in NZ. None of my 4 babies have had a popular birth date though, and well timed means that we all have different birth months!

    Turns out my birthday august the 10th is relatively common and I share it with 13500 other New Zealanders. Very interesting. Pretty cool for people born on September 22nd to have most common birth date in nz.

    This was my results. I actually share my birthday with MIL. My husband is April, sons are February and November. I have heard of friends who have really busy months. July was the busy month in my family – my Dad, my uncle, and myself.

    Mine is ranked 331 in May with my son and my other son is may he was 234 my husband was 249 and June and our August born was 179 so we are all ranked lower than off course October born people and end of September this is very interesting.

  9. Bevik1971 15/10/2018 at 11:12 am

    Mine is ranked 38 and fairly common – my daughter’s is 26 Dec ranking fairly rare at 364 haha. It’s actually a bit of a pain having her birthday then (she was 2 weeks early) as she can’t have a party on the day, none of her friends are around and it’s Boxing Day of course. So we have to have a party a few weeks before then we have a small party at home on her actual birthday 🙂

    Mine is 317th so not one of the more common ones, I wonder what everyone is doing at Christmas and New Years to make late Sept, early Oct so popular…. 😉

    Ranked 43 apparently pretty common! I’m later in October so I guess that makes sense. It’s no wonder the relaxed summer brings babies here. I personally have two babies born in the same week in May as well. I just tend to fall pregnant in July/August haha.
