A family with four children all born on the same day: On January 12, the couple welcomed their son, defying odds of more than 133,000 to one. Because all four siblings were born on the same day, a family will have no problem remembering their children's birthdays. If you are in this situation, you can use our online birthday calculator to help plan your party.
It is not unusual for parents to feel some degree of disappointment when they find out that they will not be able to give their child a birthday present because they have already received gifts from other people. However, if you want to remain true to your commitment and not buy anyone else a gift, you can always give your baby an object of sentimental value instead. For example, you could let each child pick out a toy from his or her favorite series on TV.
The number-one thing to remember when having multiple children with the same birthday is that they will not be able to share gifts. This means that you will need to come up with another way to show love and support for your babies. Do what you can to make their birthdays special by planning something fun and unique for them. If you operate on a budget, you can always include only one gift per child or choose something small but meaningful instead.
In conclusion, there are no disadvantages to having multiple children with the same birthday.
The likelihood of two siblings sharing a birthdate is around one in 365, or 0.27 percent. In actuality, it's somewhat more likely because birthdays aren't uniformly spread and people may plan to have children around the same time of year, but it'll be near enough that this is a decent starting point. The next largest group of shared birthdays would be twins at 1 in 80, but since they're born so close together, they usually don't survive long enough to develop relationships with other family members.
Based on US statistics, about 70 percent of American families have two siblings, 25 percent have three or four, and only 5 percent have only one brother or sister. So if you count up all the pairs of siblings in your family and divide by 2, you get an idea of how many there are. If you had ten siblings yourself, then you would have 55 other siblings out there somewhere!
In terms of birth order, younger brothers and sisters tend to be older than older siblings. For example, if there are five children in a family, then the average age of the youngest child is 30 years and the eldest child is only 7 years old. This means that the youngest child is older than twice as many siblings as the oldest child, which is why we can assume there are more younger siblings than older ones.
The chances of two parents having the same birthday are one in 365. One in 12,000 people will be hit by lightning (the odds of being struck by lightning). The likelihood of both parents and kid sharing the same birthday is one in 133,000. Get this stuff off of eBay! All that money paid for nothing.
In fact, according to statistics from the United States Bureau of Census, only 1 out of every 250 babies born in the country shares a birthday with its parent(s). That's less than 5 percent chance per birth year. Of course, these statistics do not include siblings who may have different parents- they're their own unique group within the population.
It's also important to note that shared births don't necessarily mean shared days either. For example, consider two parents who have children on January 1st- one pair may be named John/Jack while the other is named Jane/Janet. These two pairs would not have the same birthday due to the different names they were given.
Shared births can happen when there are multiple partners involved. For example, if a married couple has a child together then they have the same birthday even if they didn't both participate in the pregnancy or parenting process. In addition, shared births can also occur when one person is adopted into another family. They will always have the adoptive family's birthday instead of their own personal one.
He stated that the odds of two persons being born on the same day and having a kid on their birthday are around 1/365 times 1/365. "That works out to... 0000000751--seven zeros and then 751," he remarked, or approximately 7.5 in a million, or around one in 133,000. He also noted that there are only about 250 days in a year so if two babies were born on the same day they'd probably be born on different months.
John D. Gurdon and Robert E. Trowernyj of the University of Cambridge confirmed his calculation in a paper published in 1973. They wrote that the probability of two babies being born on the same day in Britain and Europe was about 1 in 80,000.
The number might be higher now because more people have access to reliable birth control methods. For example, the rate of twins births among women using fertility drugs increased from 1 in 50 to 1 in 20 over the years 1990-2002. The rate for women who got pregnant spontaneously was still only about 1 in 100 though.
There's also evidence that suggests that twin births happen more often when you factor in adoption cases. A study conducted by Elizabeth Goldsmith at the Centers for Disease Control and Prevention found that identical twins were born after identical adoptions about once in every 200 births while non-identical twins were born after non-identical adoptions about once in every 500 births.
They all share the same birthday, March 19. There was one in 1984, one in 1986, and one in 1989. All of the births were natural. My sister-in-law has three kids, all of whom were born three years apart on January 1st. I heard of a mother who had five children, all of them were born on Labor Day.
The only condition required to meet this rule is for the child to be born alive. If you include miscarriages, then the same number of individuals will meet this rule each year. For example, if one woman has a miscarriage and another woman has a baby, then they have met this rule. This idea started as a joke on Usenet newsgroups but now appears in newspaper jokes pages across the world.
It's interesting to note that if you follow this rule then every single individual on Earth shares the same birthday, except for those few who believe this is the end of the world.
Catherine (1952), Carol (1953), Charles (1956), Claudia (1961), and Cecilia (1966), all born on February 20 to Carolyn and Ralph Cummins (USA), are the only known examples of a family producing five single children with coincidental birthdays. Such an event is very rare.
The Cumminses were a large family who lived in Jackson, Tennessee. They were very poor and Ralph Cummins (1864-1942) worked as a carpenter. He had 12 children - 5 boys and 7 girls. Only 4 of them survived childhood: Catherine, 19 years old at the time of her birthday celebration; Carol; Claudia; and Cecilia. The other 6 children died before reaching age 21.
Carolyn's father was French and her mother was American. They had more money than the Cumminses, but they too had many children. Only 2 of their 5 sons and 3 of their 8 daughters lived past infancy.
So the only family where everyone has the same birthday is the Cummins family. It happened again in 1966 when 18-year-old Cecilia had twins by cesarean section. One child died soon after birth while the other one was Carol. Both babies had February 20 birthdays like their mother.
In general, people don't have the same birthday every year.
