To. Compute. Knowing which twin is the older one is usually a no-brainer. The time of birth is recorded, and whichever one is born first is officially the eldest.
As a parent of twins, I'm pretty sure that you know the answer to the question “which twin is older?” It is, of course, the child that was born first.
Most often, fetuses known in utero as twin A are also first born and thus retain their label. However, this is not always the case, such that the twin A newborn was previously labeled twin B in utero and vice versa.
On September 1, sisters Umeno Sumiyama and Koume Kodama turned 107 years and 300 days old, officially breaking the record for the world's oldest living identical twins. The Japanese siblings are also the oldest identical twins to have ever lived.
Congratulations to Umeno Sumiyama and Koume Kodama. They have been certified as the world's oldest living identical twins by Guinness World Records. Born in Japan on November 5, 1913, they are the third- and fourth-born of 11 siblings - breaking records at 107 years young. Omedetou gozaimasu.
Concie Marshall and Leila Moag, who were born in Berry, are the oldest surviving identical twins in Australia and very likely the world. On Thursday, April 29, the twins were joined by family and friends at a morning tea in Bupa Berry to celebrate their record-setting 102nd birthday.
There are cases of twins born in different years. In Texas, twins were born only one minute apart, but in different years, delivered by C-section as the last baby of 2013 and the first baby of 2014. A similar situation occurred as 2015 changed to 2016 in San Diego with fraternal twins.
Twins with different birthdays are rare, and the chance of twins being born in different years is 1 in 2 million, according to the news release by Natividad. Though the incident is rare, it's not the first time twins have been born in separate years.

Medically, this 7-year defect is very rare. Twins are typically born with a bit of a delay — a few minutes to a few hours. Some even have separate birthdays, due to being born just before and just after midnight. The Zeitgest girls were not only born 7 years apart, but Ms.
Classically, the bigger twin is the more physically dominant. It's basic human nature, and particularly applicable to boys as they hit puberty. It happens often with singleton siblings too… the older is bigger and enforces him/herself through physical dominance.
Twins often exchange dominance throughout their lives, and in that sense may alternate between birth order categories. Aside from inherent personality traits, the impact of birth order in multiples is likely more often one of perception rather than reality, especially in light of recent studies.
As expected, first-born twins had greater birth weight than second-born twins. With respect to height, first-born twins were slightly taller than second-born twins in childhood.
The time between giving birth to your first and second baby varies from woman to woman, but the second baby is usually delivered within about 30 minutes to an hour after the first. In very rare cases, some women deliver 1 twin vaginally and then need a caesarean section to deliver the second twin.
In 99.9% of cases boy/girl twins are non-identical. However, in some extremely rare cases resulting from a genetic mutation, identical twins from an egg and sperm which began as male (XY) can develop into a male / female pair.
If you're the firstborn child, your birth order would be referred to as the oldest child. If you're the second born, you're a middle child—however, there can be multiple middle kids in a family. If you're the last sibling to be born, you're the youngest child or the baby of the bunch.
/ˈɛldɪst/ Someone who's described as eldest in their family was born first. Your eldest sister is the oldest one. Use the adjective eldest when you're describing people in terms of birth order: the oldest is the eldest.
There are more twins in the “millennial generation” than any other generation, thanks partly to a twin boom in the '90s. The main reason was a new technology called in vitro fertilization, which in its early days frequently produced twins, triplets and other multiple births.
What is the likelihood of having more than one set of twins? If existing twins are identical the chance of having another set is the same as most women, about 1 in 250. If the twins are non- identical the chances of having twins again are much higher.
The longest interval between the birth of twins is 90 days, in the case of Molly and Benjamin West, dizygotic (fraternal) twins born in Baltimore, Maryland, USA to parents Lesa and David West (all USA) on 1 January and 30 March 1996.
It's also possible to have twins that were conceived at different times in a process called superfetation. In exceedingly rare cases, a woman might release two eggs during ovulation, but not at the same time. In such cases, twins may actually be born on different days.
Can twins have different fathers? In rare cases, fraternal twins can be born from two different fathers in a phenomenon called heteropaternal superfecundation. Although uncommon, rare cases have been documented where a woman is pregnant by two different men at the same time.
When people refer to Irish twins, it's important to recognize that although the siblings are close in age, they are not actually twins. In other words, they were not born during the same gestational period. Calling them Irish twins is just an informal way of classifying siblings that are born close together.
Irish twins is the term for siblings born in the same calendar year or within 12 months of each other.
