In the U.S., certain months are set aside to celebrate and honor different diversity groups. May is AAPI Heritage Month, also known as Asian American and Pacific Islander Heritage Month.

The countries of origin that constitute Asian Pacific America are Japan, China, Taiwan, Korea, Vietnam, Laos, Cambodia, the Philippines, Samoa, Fiji, Guam, the U.S. Trust Territories of the Pacific or the Northern Marianas.

To honor the achievements of Asian/Pacific Americans, the U.S. Congress designated the month of May as "Asian/Pacific American Heritage Month" in 1992.  Asian/Pacific American Heritage Month was renamed as AAPI Heritage Month in 2009.

In 1978, a joint congressional resolution established Asian/Pacific American Heritage Week. The first 10 days of May were chosen to coincide with two important milestones in Asian/Pacific American history: the arrival in the United States of the first Japanese immigrants (May 7, 1843) and contributions of Chinese workers to the building of the transcontinental railroad completed May 10, 1869. 

 In 1992, Congress expanded the observance to a monthlong celebration that is now known as Asian American and Pacific Islander Heritage Month. Per a 1997 U.S. Office of Management and Budget directive, the Asian or Pacific Islander racial category was separated into two categories: one being Asian and the other Native Hawaiian and Other Pacific Islander.
