Three years ago Friday, the city of Boston was forever changed when a pair of bombs were detonated at the finish line of the Boston Marathon, killing three spectators and injuring hundreds. Marathon Monday remains a day of celebration in Boston whereas April 15 is a somber day of mourning.

Boston Mayor Marty Walsh officially proclaimed that April 15 will be known as One Boston Day, and the city will use the holiday to honor the victims of the marathon bombings through acts of kindness and celebrations of traditions unique to Boston.

The day features events common to many memorial days, such as a moment of silence at 2:49 p.m. to remember the victims as well as wreath ceremonies at the sites of bombings and a blood drive in honor of those wounded.
