Mississippi Code Title 3. State Sovereignty, Jurisdiction and Holidays § 3-3-15

The state flag may be displayed from all public buildings from sunrise to sunset; however, the state flag may be displayed from all public buildings twenty-four (24) hours a day if properly illuminated. The state flag should not be displayed when the weather is inclement, except when an all-weather flag is displayed. The state flag shall receive all of the respect and ceremonious etiquette given the American flag. Provided, however, nothing in this section shall be construed so as to affect the precedence given to the flag of the United States of America.
