Mayor Martin J. Walsh launched the “One Boston Day” website Monday, which allows people to share how they will be remembering the April 15, 2013, Boston Marathon, officials said.

People, businesses, and community organizations are encouraged to let people know how they are observing the day of the Marathon bombing by using the hashtag #OneBostonDay on social media, the Mayor’s office said in a press release. Those who use the hashtag will be featured on the website onebostonday.org.

“One Boston Day will inspire all of us to come together as the community we are and share the spirit of Boston by giving back,” Walsh said in a statement. “April 15 is a date that has come to stand for our city’s deepest values. I hope everyone can mark this day in a way that is appropriate and inclusive for each of our experiences.”


According to the mayor’s office, the day is about sharing random acts of kindness and spreading goodwill. The idea for the day came from survivors of the 2013 Marathon terror bomb attack who wanted to pass along the love and support they received from others in the wake of the attack.

The website currently features local groups that are getting involved, including St. Francis House, a homeless shelter; WZLX-FM (100.7), a classic rock radio station; and the Joshua Eaton School in Reading. There is also a box where people can tweet what they are doing for the day, and see a scroll of what other people are doing.

Last month Walsh announced he was declaring April 15 “One Boston Day,” a day to honor the resilience, generosity, and strength of the city after the Marathon attack.

On April 15, Walsh will assist in raising banners on Boylston Street to honor the victims and survivors of the bombing. At 2:49 p.m. the city will hold a moment of silence to mark the two-year anniversary.
