National Twin Day - December 18
Mon Dec 18th

National Twin Day

All the siblings who enjoy the special relationship because they share a birthday are commemorated on December 18th.

Twins, whether fraternal or identical, share everything right from the start. Although their personalities may be different, they often know what the other is going to say before the words are spoken. Distance isn't an issue either. Twins can stay connected whether you live in the United States or around the world.

Of course, mythology teaches us about twins from the very beginning, as does the Bible. We explore a variety of human conditions, from Esau and Jacob's rivalry to Aphrodite's twin sons Phobos and Deimos to Aphrodite's Phobos and Deimos, as well as the constellation's mortal and immortal twins Gemini.

Notable twins

We've been fascinated by twins for many years, as well as the years. Literature embraced the twin duplicity with a sense of excitement. For example, Shakespeare's Twelfth Night and the confusing that ensues with Sebastian and Viola are examples. When twins are depicted in modern-day sitcoms, we are left in tears. Phoebe Buffay of the sitcom Friends and, more recently, Sheldon Cooper from The Big Bang Theory humbly portrayed their twin lives..

We're sure that real-life twins intrigue us. As twins enter the White House, we are sure to pay attention, as was the case with Barbara and Jenna Bush in 2001. Of course, we feel like they're relatives when they play magical characters like James and Oliver Phelps in the Harry Potter series. Of course, we're family. We loved them as Fred and George Weasley's roles as Fred and George Weasley kept us coming back for more.

Some twins have the same passions. For example, Mark and Scott Kelly, both became astronauts, and they have contributed not only to space exploration but also to scientific research. Jocelyne Lamoureux-Davidson and Monique Lamoureux's passion for hockey brought them together on the U.S. Olympic Hockey Team.

Twins have so much more than DNA.. Many of them don't even look alike. The majority of them don't even look alike. One thing is for sure, they celebrate National Twin Day.
