About National Centenarian’s Day
National Centenarian’s Day takes place every year on 22 September, honouring people who have reached the age of 100 or more. In 2026 it falls on Tuesday, 22 September. The day recognises the lives, wisdom, and contributions of centenarians, and encourages families and communities to celebrate longevity and the stories that come with a full century of living.
What is National Centenarian’s Day?
National Centenarian’s Day is an observance dedicated to people who have lived for 100 years or more. It is marked primarily in the United States, where care homes, families, community groups, and senior organisations use the occasion to celebrate their oldest members. The day is about more than reaching a milestone number. It invites younger generations to listen to the experiences of those who have witnessed an entire century of social, technological, and cultural change. In 2016, the United States Senate formally designated 22 September as a day to recognise Americans who have reached the age of 100 or older.
When is National Centenarian’s Day?
National Centenarian’s Day is observed on 22 September every year. In 2026 it falls on a Tuesday. The date is fixed and does not move, so it is easy to plan visits, parties, and community events well in advance. Because the date never changes, the same day can become an annual tradition for families with a centenarian relative or for care homes marking the achievements of long-lived residents.
Why National Centenarian’s Day Matters
The number of people reaching 100 is growing rapidly. Recent estimates place the centenarian population in the United States at roughly 72,000, while the United Nations has counted more than half a million centenarians worldwide. As life expectancy rises, this group is projected to expand further in the coming decades, making the conversation around healthy ageing increasingly relevant.
Centenarians are living records of history. A person turning 100 in 2026 was born in 1926, before television was commonplace and decades before the internet. Their memories span world events, family migrations, and everyday details of life that no textbook captures. Setting aside a day to honour them helps combat the social isolation that many older adults experience, and it reminds society to value the knowledge and resilience of its oldest members.
How to Get Involved in National Centenarian’s Day
There are many warm and meaningful ways to mark the occasion, whether you know a centenarian personally or simply want to celebrate longevity in your community.
- Visit a centenarian – Spend time with a relative, neighbour, or care home resident who has reached 100. A simple conversation can mean a great deal and gives you the chance to hear remarkable life stories.
- Record their memories – Bring a phone or recorder and capture their reflections. These recordings become treasured family heirlooms and preserve history for future generations.
- Organise a celebration – Arrange a small party with favourite foods, music from their era, and familiar faces. Care homes often host group celebrations for all their oldest residents.
- Send a card or letter – If you cannot visit in person, a handwritten card shows you are thinking of them and brightens their day.
- Volunteer at a care home – Offer your time to a local residential home, where staff often welcome extra hands and company for residents on special days.
- Share their story – With permission, post about a centenarian you admire on social media using #CentenariansDay to inspire others to celebrate the older people in their lives.
- Learn about healthy ageing – Use the day to read about the lifestyle factors linked to longevity, from diet and movement to strong social connections.
- Connect across generations – Encourage children and grandchildren to ask questions and build relationships with the oldest members of the family.
History of National Centenarian’s Day
National Centenarian’s Day is widely credited to the staff of a nursing home in Williamsport, Maryland, who wanted to recognise their oldest residents and remind the wider community of the value older adults bring. The early celebrations encouraged people to sit with centenarians and listen to the stories they had to tell, treating their long memories as a resource to be cherished rather than overlooked.
As word of the observance spread, more care homes, families, and community groups adopted it, and the tradition gathered momentum across the United States. Local newspapers and senior organisations began to feature centenarians each September, profiling their lives and the secrets they credited for their longevity.
The day gained further standing in 2016 when the United States Senate designated 22 September to honour Americans who had reached the age of 100 or older. This formal recognition helped cement the date in the national calendar and gave families and institutions an official occasion around which to plan their celebrations.
