Asian American Pacific Islander Heritage Month is celebrated in May to honor the contributions and achievements of individuals from Asian and Pacific Islander backgrounds in the United States. This month recognizes the rich cultural heritage and history of these communities, highlighting their impact on American society. The observance began in 1978 when Congress passed a resolution to establish a week of recognition. In 1990, it was expanded to a month-long celebration. Events and activities during this time often include cultural festivals, educational programs, and community gatherings that promote understanding and appreciation of AAPI cultures.
