Spotlight: National Hispanic Heritage Month (Sept 15–Oct 15)
Picture a street festival in late September: the aroma of fresh tamales and sweet tres leches cake fills the air, the rhythms of salsa and mariachi music invite everyone to dance, and families proudly wave flags from Mexico, Cuba, Puerto Rico, and more. This vibrant scene can only mean one thing – National Hispanic Heritage Month has arrived. Observed each year from September 15 to October 15, Hispanic Heritage Month honors the histories, cultures, and contributions of over 62 million Americans of Hispanic/Latino ancestry. It’s a time to recognize the profound impact of Hispanic and Latino communities in the U.S., from shaping our national cuisine and music to driving innovation in business and science.
Why does it start in mid-September? The timing is no coincidence. In 1968, President Lyndon Johnson proclaimed the first Hispanic Heritage Week; it was later expanded to a month-long celebration in 1988 to allow more time to honor these contributions. The mid-month start date was chosen to coincide with several Latin American countries’ independence anniversaries. September 15 is Independence Day for Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua (all in 1821); September 16 is Mexico’s, and September 18 is Chile’s. This period was seen as a fitting window to celebrate freedom and heritage. Every year since, Americans have embraced these dates to kick off 30 days of festivities celebrating Hispanic identity.
