When Is National Twin Day 2024. This special day has been around since the 1980s and is dedicated to honoring twins everywhere. This year, national twins day will be celebrated from august 5 to august 7.

Two peas in a pod, mirror images — whatever you call them, twins are a unique miracle, and that’s probably why we have a day called national twins day, celebrated over the first full weekend of august. On december 18th, national twin day celebrates all the siblings who enjoy the unique connection because they share a birthday.
