Immediately after the Marathon bombing on April 15th, 2013, Bostonians responded to violence and hate with selflessness and love.

It was in that spirit that One Boston Day was born, encouraging people everywhere to commit random acts of kindness, big and small.

Over the years, this continued show of support has inspired the survivors and family members of the victims to connect, heal, and pay the kindness forward in ways both inspiring and profound.

Mayor Michelle Wu and the Boston Athletic Association (B.A.A.) will mark One Boston Day with a wreath laying on Boylston Street and volunteer events. One Boston Day honors the victims, survivors, and first responders of the tragically historic 2013 Boston Marathon.

Residents are encouraged to participate in service events hosted by the City and its partners, or to take part in their own acts of kindness. Click here to find a list of volunteer events and more information.

In every year since its official establishment in 2015, on April 15, #OneBostonDay has been a leading trend nationally on social media. Last year alone there were over 43,000 posts across social channels. As in the past, Hill Holiday is serving as the creative and digital marketing partner to help spread awareness and raise the visibility of One Boston Day.
