Calling them Irish twins is just an informal way of classifying siblings that are born close together. Some actual twins have different birthdays due to one being born on one day and the other staying in the womb for days or weeks longer.

This means that if a person was born in 1997, then their platinum birthday would be their 97th birthday. With many commenters saying that the year dictates your platinum birthday, there were a lot of Gen Zers upset that they missed out on their special day.
There are about 120,000 twin births in the USA every year, slightly more than 3% of all births. 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.
Due to probability, sometimes an event is more likely to occur than we believe it to. In this case, if you survey a random group of just 23 people there is actually about a 50–50 chance that two of them will have the same birthday. This is known as the birthday paradox.
A half-birthday is a day approximately six months before or after the anniversary of a person's birth.
Description. What is a Golden Birthday? Your golden birthday is when the date of your birth coincides with your age. For example, if you were born on October 8, your golden birthday took place when you turned 8. If you were born on December 21, your golden birthday took place when you turned 21.
What's the chance that two people share the same birthday? The first person can be born on any day of the year, this means that the probability is 365/365 = 1. The second person has to be born on the same day as the first and there is a 1/365 chance of that happening.
A Beddian Birthday is a year in which your age matches the last two digits of the year you were born.
The term “Irish Twins” refers to siblings born within a year of each other, and it definitely does happen. While birthing two babies in the span of a year has its challenges, there are also many uniquely special benefits to raising siblings close in age.
Not many twins can say they have different birthdays, and even fewer can say they have different birth years. There is about a one in 2 million chance that twins will be born in different years, but newborn twins Annie Jo Scott and Effie Rose Scott joined this ultra-rare club on New Year's Eve.
“A joint birthday party is when brothers, sisters or friends with birthdays close on the calendar have one big party together instead of celebrating individually,” says event and party planner Jordan Stringfellow, owner of Jordi & CO Events in Southern California.
December 25 (Christmas Day) is the least common birthday, while January 1 (New Year's Day) is the second least common.
In a room of just 23 people there's a 50-50 chance of at least two people having the same birthday. In a room of 75 there's a 99.9% chance of at least two people matching. Put down the calculator and pitchfork, I don't speak heresy. The birthday paradox is strange, counter-intuitive, and completely true.
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.
(Identical twins come from a single fertilized egg that splits in half, while fraternal twins occur when two different eggs are fertilized simultaneously). So, how many months apart are Irish twins? It's technically possible for two siblings to be as close as 9 or 10 months apart.
According to real birth data compiled from 20 years of American births, mid-September is the most birthday-packed time of the year, with September 9th being the most popular day to be born in America, followed closely by September 19th.
