Which of the following is NOT a guideline for displaying the flag?

The guideline stating that the flag should only be displayed during national holidays is incorrect because the United States flag can be displayed at any time, not just on holidays. In fact, proper flag etiquette emphasizes that the flag should often be flown to demonstrate respect and pride in the nation.

The other statements reflect accepted practices for flag display. For instance, flying the flag from sunrise to sunset or illuminating it at night ensures that it is visible and honored at all times, particularly important during patriotic events. Furthermore, it is a long-standing custom to avoid letting the flag touch the ground, as doing so would be seen as a sign of disrespect. Moreover, displaying the flag on public buildings and schools signifies the role of those institutions in representing and serving the community and the country, reinforcing national pride.
