May is Asian Pacific American Heritage Month
In 1977 the U.S. Congress (spearheaded by Representative Frank Horton of New York and Senator Daniel Inouye of Hawai'i) chose the first ten days of May to commemorate the history and contributions of Asian American communities here in the U.S. The week's observance became a month, the very month in which the first Japanese immigrants came to the U.S. in 1843. We also commemorate the completion of the transcontinental railroad on May 10, 1869 as the majority of workers who laid those railroad tracks were Chinese immigrants. And that's why AAPI Heritage Month is in May. (https://www.pbs.org/articles/celebrate-asian-american-and-pacific-islander-heritage-month/)
The theme for the 2024 Asian American Pacific Islander Heritage Month is "Advancing Leaders Through Innovation."
