National Centenarian's Day – September 22, 2024

National Centenarian’s Day is observed annually on September 22. It is a day set aside to celebrate and honor those who have reached the age of 100. The day was originally proclaimed as a time to partake in the rich history and wisdom shared by centenarians. Listening to their life stories is ever so inspiring, and this is one day to be cherished by everyone to honor those among us who have seen a century go by.

History of National Centenarian's Day

Over the years, the human population and life expectancy have increased with a corresponding increase in the number of people who attain the age of 100. According to the United Nations, there are over 570,000 centenarians in the world currently. According to a 1998 demographic survey, Japan is expected to have 272,000 centenarians by 2050, with other sources suggesting the number could be much higher.

National Centenarian’s Day is a day to celebrate and honor those among us who have lived an entire century and to share in their wisdom, joys, and life as a whole. These precious members of society have seen the tragedies of the Great Depression and World Wars, the advent of the talking picture, the golden age of the radio and the invention of television, innovation of air travel, all the way to the exploration of space and the digital revolution — all in one lifetime.

Many cultures offer blessings and some countries give gifts to those who attain this age. Centenarians are often the subject of news stories, which often highlight the fact that they are over 100 years old. These reports provide cultural historians and researchers with deep insight into how the rest of society views this elderly population.

Centenarians will always be with us at each point in history, and all the memories of the lives they’ve lived will continue to live on when passed down.
