The flag should be displayed in all government buildings, official residences, public plazas, and schools every day throughout the year. All other places as may be designated by the National Historical Commission as such. The days of May 28 (National Flag Day) and June 12 (Independence Day) are designated as flag days, during which all offices, agencies and instrumentalities of government, business establishments, institutions of learning and private homes are enjoined to display the flag. But in recent years, the flag days are now from May 28 to June 30 yearly to promote patriotism and to celebrate the nation's independence.
