This bill mandates that all national cemeteries administered by the Department of Defense, the Department of Veterans Affairs, or the National Park Service must be open to visitors on legal public holidays . The legislation specifically references the holidays defined in section 6103(a) of title 5, United States Code, ensuring a consistent standard for public access. The primary aim of this measure is to guarantee that individuals can visit these significant sites of remembrance on days when many observe national events. By requiring open access on these holidays, the bill seeks to honor those interred and provide opportunities for public commemoration. This ensures uniform visitor access across all federal agencies managing national cemeteries.
