Great article! I’d loved to come up to see it. But I’m a bit confused — the article mentions June 20 and September 19/20 for the Dragon Boat Festival. Which date is correct for the event?

Hi Naomi,
Thanks for your question! The Dragon Boat Festival official holiday is June 20 this year, but the San Francisco International Dragon Boat Festival event is on September 19/20 on Treasure Island in San Francisco. It is a bit confusing that the actual race events are held here in U.S. cities across the summer months!
Hope this helps clear it up.
