A parade will now be held on Oct. 30, the letter to parents said.

Elizabeth Fester said the district came to a decision with members of the PTA to originally have an event outside the school day so more families could participate.

Fester said the school district did not ban Halloween, but rather changed how the school would celebrate.

A petition on Change.org was started by Rebecca Lilley, a parent who said she is happy with the change of heart, but didn't like the tone of the letter, The Connecticut Post reported.

"We were never attacking the integrity of the Milford school system," Lilley said.

But one of the organizers said that the after-school event would have included a parade, dance and trick-or-treating.

"We knew what the real deal was," Christopher Thomas said.
