Are twins still twins if they are born in different years?

Yes, twins are still twins even if born in different years because they come from the same pregnancy, often occurring when labor crosses midnight, especially around New Year's Eve, making one twin the last of the year and the other the first of the next. This rare event results in them having different birthdays, months, and even years, sometimes leading to different age groups for school or sports, as seen with numerous documented cases around the millennium and recent New Years.

Are twins still considered twins if they are born on different days?

Yes! Twins are defined as children produced in the same pregnancy. Usually, they are delivered only a few minutes or hours apart. But they can have different birthdays.

Can twins be born 2 years apart?

Yes, twins can be born two years apart, most commonly when one twin arrives just before midnight on New Year's Eve and the other just after midnight on New Year's Day, creating different birth years, but they can also be born days, weeks, or even months apart due to natural labor variations or scheduled C-sections. The longest interval between twins is even longer, with one case spanning 87 days, though typically it's a matter of hours or days around year-end.
 

How rare is it for twins to have different birthdays?

Twins being born on different days is rare but happens, most commonly by minutes around midnight (especially New Year's Eve/Day), but can also occur days or even months apart due to medical interventions like delaying a premature birth to help the second twin develop, with rare cases spanning years or even centuries. The odds for a few minutes difference are higher, while being born in different years is extremely rare, estimated around 1 in 2 million for some cases.

What is a diamond birthday?

A diamond birthday is a special milestone when your age matches the last two digits of your birth year, like turning 75 if born in 1975, or turning 81 if born in 1981, often celebrated with sparkly, diamond-themed parties to mark a life well-lived, sometimes called a platinum birthday too. 

What are twins called born a year apart?

Twins born a year apart are informally called "Irish twins," a term for siblings born less than 12 months apart, often resulting from a pregnancy shortly after a previous birth, though the term has a derogatory history and is sometimes seen as insensitive. While medically they're just close-in-age siblings with a short interpregnancy interval, "Irish twins" captures the unique dynamic of having children so close in age, sometimes even in the same calendar year, say WebMD and BabyCenter. 

What is a daisy baby?

A "Daisy Baby" is a term for babies affected by Twin to Twin Transfusion Syndrome (TTTS), a serious condition in identical twins sharing a placenta, or related complications like TAPS, SIUGR, and TRAP. The name comes from the Twin to Twin Transfusion Syndrome Foundation (TTTSF), symbolizing twins thriving like daisies after surviving the "storm" of the condition, with their logo often showing two daisies from one stem, representing the shared life and journey. 

What's the smallest age gap between siblings?

The smallest age gap between non-twin siblings can be just a few months, often around 7-9 months, if the younger child is born prematurely and the mother conceived again very soon after the first birth, though this is medically risky; the term "Irish Twins" describes siblings born less than 12 months apart, with gaps of 9-10 months being possible if conception happens soon after birth.
 

Which parent carries the twin trait?

For fraternal (dizygotic) twins, the genetic tendency for hyperovulation (releasing more than one egg) is often passed through the mother's side, meaning the pregnant parent's genes are key, but the father can carry and pass this trait to his daughters, increasing their future chances. For identical (monozygotic) twins, genetics play a minor role, as they usually occur randomly when one fertilized egg splits, though some rare genetic factors might influence the split.
 

Why can't you say siamese twins?

You can still say "Siamese twins," but it's outdated and often replaced by the more accurate and sensitive term, "conjoined twins," because the original term links to historical "freak shows," isn't geographically accurate for most cases (as it comes from Chang and Eng Bunker of Siam, now Thailand), and can feel dehumanizing, similar to outdated terms for other conditions. "Conjoined twins" is the preferred medical and respectful term for twins physically joined in utero.

What is the meaning of Dutch twins?

"Dutch twins" (or "Catholic twins") is a slang term for siblings born very close in age, usually within 12 months, similar to "Irish twins," originating from the idea that Catholic families avoided birth control, leading to closely spaced children. It's not a medical term but describes children with a short interval between births, sometimes meaning the mother conceived the next baby when the first was around 3 months old.
 

Are twins due to mother or father?

Twins are due to both mother and father for the sperm/egg fertilization, but the likelihood of having fraternal twins (non-identical) is primarily influenced by the mother's genetics, specifically a tendency for her to release multiple eggs (hyperovulation). The father's genetics don't directly affect this, though they can pass genes to his daughters that increase their chance of hyperovulating. Identical twins, however, happen from one egg splitting and aren't strongly hereditary in the same way.
 

What are momo twins?

Monoamniotic twins are identical twins that share an amniotic sac, the fluid-filled sac that holds the baby during pregnancy (also known as the “bag of waters”). Normally, identical twins each have their own amniotic sac. Monoamniotic twins are a rare type of “monochorionic” twins, meaning they also share a placenta.

The lowest risk of perinatal death in twin pregnancies at 38 weeks gestation corresponded to that observed in singleton pregnancies at 43 weeks gestation [7].

What is an Emerald birthday?

An Emerald Birthday is a special, rare birthday when the age you turn matches the number of your birth month (e.g., turning 5 if born in May, or 11 if born in November), making it a unique, once-in-a-lifetime celebration for those born in months 1 through 12, often associated with the May birthstone.
