BOSTON —  Two years ago, April 15th, 2015, the beginning of a new annual Boston tradition, One Boston Day, was created.

Each year, the day serves as an opportunity to celebrate the resiliency, generosity, and strength demonstrated by the people of Boston and those around the world in response to the tragedy of April 15th, 2013 where two bombs went off at the finish line at the Boston Marathon.

Mayor Marty Walsh and Governor Charlie Baker commented on the importance of the day, along with former Vice President Joe Biden.

One Boston Day asks everyone: How will you make a difference this year?
