Having a birthday on a major holiday can be a special occasion for many, but did you know that some birthdays are actually rarer than others? While holidays are a popular time for baby making, babies are less likely to be born on popular holidays. Christmas, New Years, Christmas Eve, July 4th, Halloween, and some suspiciously Thanksgiving days all make the top 10 least common birthdays. So why is the rarest birthday?
The answer lies in the fact that certain holidays are more popular times to conceive. According to a study conducted by the National Center for Health Statistics, the most popular conception days of the year were Christmas Eve, New Year’s Day, and Valentine’s Day. The study also found that most conceptions occurred on Fridays and Saturdays, likely a result of couples having more time off from work.
The rarest birthdays, then, are those days that fall outside of the popular holidays, as well as those that fall on the days that are the least likely to be conception days. This means that birthdays on Memorial Day, Labor Day, Independence Day, and Thanksgiving Day are among some of the rarest birthdays.
Popular Holidays are Less Likely Birthdays
As mentioned earlier, popular holidays are less likely to be birthdays. This is because those are the days that couples are more likely to conceive. Not only are couples more likely to conceive on these days, but they are also more likely to give birth on these days as well.
This is because of the length of gestation. Gestation periods vary from person to person, but on average, it takes around 40 weeks for a baby to be born. This means that if a couple conceives on a particular holiday, the baby is likely to be born on or around that holiday.
For example, if a couple conceives on Christmas Eve, the baby is likely to be born around the middle of October. This makes the birthday of October 15th one of the rarest birthdays. Likewise, if a couple conceives on New Year’s Day, the baby is likely to be born around the middle of August. This makes the birthday of August 15th one of the rarest birthdays.
Unpopular Birthdays are More Common
While popular holidays are less likely to be birthdays, there are some days that are more likely to be birthdays. These are the days that are the least likely to be conception days. This means that birthdays on Memorial Day, Labor Day, Independence Day, and Thanksgiving Day are among some of the most common birthdays.
These days are also more likely to be birthdays because they are less likely to be conception days. For example, if a couple conceives on Memorial Day, the baby is likely to be born around the middle of March. This makes the birthday of March 15th one of the most common birthdays. Likewise, if a couple conceives on Independence Day, the baby is likely to be born around the middle of November. This makes the birthday of November 15th one of the most common birthdays.
Conclusion
The rarest birthday is one that falls outside of popular holidays, as well as those that fall on the days that are the least likely to be conception days. Popular holidays are less likely to be birthdays because those are the days that couples are more likely to conceive. Unpopular birthdays are more common because they are less likely to be conception days. Ultimately, the rarest birthday depends on when a couple conceives and how long the gestation period is.
