Della Hardman Day is returning for its 20th anniversary this Saturday.

The day celebrates Ms. Hardman, a longtime Vineyard resident known for her work as an educator, mentor and writer. The tradition began in 2005 in Oak Bluffs, which has set aside the last Saturday of July for two decades as a celebration and tribute to Ms. Hardman, who urged everyone to “Savor the Moment.”

Over the years, notable guests such as Charlayne Hunter-Gault and Clarence B. Jones have spoken at the event. A high school essay contest has also been a staple of the event.

“When the conversation began two decades ago, I had no idea that it would be so appealing and such a unifying decision,” said Andrea Taylor, Ms. Hardman’s daughter.

But after two decades, the event will be going through some changes, including moving to Vineyard Haven. This year it takes place at the Martha’s Vineyard Museum, beginning at 4 p.m. on Saturday, July 26.

Ms. Taylor said the time had come to re-examine the celebration, particularly in light of needing to find a more sustainable funding and organizational model. Each year, organizers have relied on individual donors, but Ms. Taylor said that they come and go.

“We’ve had really 20 years, a good run, but we want to see what else we might do or how else we can operate even more efficiently,” she said.

For this year’s event, Ms. Taylor will highlight the breadth of her mother’s work, showcasing her mother’s archives, which are preserved at Boston University.

“We’re hoping to talk about that and see if we can use my mother’s collection as an example that will hopefully inspire other people to collect their materials,” she said.

Natalie Wambui, who immigrated to the United States from Kenya when she was 13 years old, will be the featured speaker. Ms. Wambui graduated from Martha’s Vineyard Regional High School this spring, and is also the author of three books. She met Ms. Taylor after moving to the Island in 2021.

Ms. Wambui noted how Ms. Taylor has become an inspiration for her.

“She has been very close to me and my family,” Ms. Wambui said. “Going to these events, it is such an inspiration to see how Andrea has been able to connect with so many people in the community and shine a light on who her mom was.”

Bringing young people together to celebrate Della Hardman Day is important to Ms. Taylor because it honors her mother’s interest in youth development.

“None of us is here to stay, was a saying my mother used constantly,” Ms. Taylor said. “What I would like to see happen...is that the next generation will be interested in keeping this. We’ve built a community of people and we’ve had many timely and compelling presentations. So the question is, what’s next?”

Ms. Taylor’s focus on finding opportunities for future generations is a goal she shares with her mother. She recalled that her mother would help her students however she could, including driving them to graduate school interviews they otherwise would not be able to make.

“She saw a possibility in everybody that she met,” Ms. Taylor said. “She would help them in a very literal kind of way.”
