The vigil, set for 6 p.m., is being organized by the Interfaith Clergy Association of Westport and Weston. The event will be moved to the steps of Town Hall if the weather proves to be too inclement.
Clergy of all faiths will gather for a series of readings and prayers as the community remembers the 20 first-graders and six educators killed in the shootings on Dec. 14, 2012.
"This is an opportunity for us to come together, one year later, in prayer, reflection and hope," Rabbi Jeremy Wiederhorn of the Conservative Synagogue, the president of the clergy group, said in a press release announcing the vigil.
Last year, the Interfaith Clergy Association held a similar vigil in the days following the shooting that was attended by several hundred members of the community.
