BOSTON (CBS) – Vice President Joe Biden, actor Mark Wahlberg, Sen. Elizabeth Warren and Red Sox icon David Ortiz were among the familiar faces in a video released Tuesday urging residents to participate in “One Boston Day,” which will now be an annual tradition.

On Monday, Boston Mayor Marty Walsh issued a proclamation that permanently designates April 15 as One Boston Day in the city.

The day “encourages random acts of kinds and spreading of goodwill.” One Boston Day was created last year as a way to give back to the community that came together in the aftermath of the 2013 Boston Marathon bombings.

A moment of silence will be held at 2:49 p.m. on April 15 in the city, marking the third year since the bombings.

Church bells will ring throughout Boston at that time.

In a video posted on the One Boston Day website, local and nationally recognizable figures encouraged residents to participate.
