National Centenarian’s Day | September 22


On September 22nd, National Centenarian’s Day honors those who’ve celebrated 100 birthdays or more. 


Initially, the day urged people to listen to the stories centenarians had to tell. Their rich history and wisdom offered a wealth of information. As the celebration spread, groups formed to honor centenarians in various ways. Often, listening to their life stories proves the age-old saying that with age comes wisdom.

Recent 2019 estimates place approximately 72,000 centenarians in the United States alone. The youngest of those were born after the end of World War I and the signing of the Treaty of Versailles. They represent a living history full of stories not found in history books. Their stories animate and compliment what we already know. Listening to their tails of accomplishment and perseverance highlight and magnify the events of the past.

At the same time, their personal histories create something legendary for those who hear them. Traditions we no longer practice or turns of phrase come traipsing across their memories to be revived and shared once more. Tribulations and experiences long forgotten reflect in their eyes. We benefit from every story they tell and every remembrance they share. 


Visit with a centenarian and tap into a wealth of knowledge, entertaining stories, and traditions from a time gone by. Celebrate their liveliness, uniqueness and their longevity. Try these other fun ways to celebrate, too!
