Halloween is Sunday.
Mayor John Nalbandian said so Tuesday night, designating the city's official trick-or-treat time for 6:30 p.m. to 8:30 p.m. Oct. 31.
As part of his "Beggars Night" proclamation, Nalbandian said homeowners should turn on their porch lights to help costumed youth; parents should accompany children and inspect their treats; and trick-or-treaters should to remain in familiar neighborhoods, wear safe clothes and use sidewalks when venturing between houses.
Commissioner Bob Moody dismissed the suggestion of observing Halloween on Saturday night. Moody and his two sons -- Tristan (the astronaut) and Sterling (a vampire-chicken) -- plan to rake in the candy Sunday evening.
"We went with the traditional Halloween," he said, referring to the proclamation.
Even so, other festivities will get a head start Saturday evening with trick-or-treating at downtown shops and at the Lawrence Riverfront Plaza Factory Outlets. A costume parade will begin at 5 p.m. in the outlet center, Sixth and New Hampshire streets. Trick-or-treating along Massachusetts Street will be from 5:30 p.m. to 6:30 p.m.
From 5 p.m. to 7 p.m., Sunflower Cablevision will serve hot dogs, drinks and coffee during its Toys for Tots launch party, in the parking lot outside 644 N.H.
