Flags and flag holders are only permitted in individual graves during a 17-day period over the Memorial Day, Independence Day, and Veterans Day holidays. Seven days prior to the upcoming holiday, flags and flag holders are made available in front of the cemetery office, while supplies last. These are for your use at Calvary Cemetery only. They will be removed on the 10th day after each holiday. If you wish to retain your own flag and/ or flag holder for reuse, you must remove it before that date.
