when is the first democratic debate

The first Democratic debate for the 2020 presidential primary took place over two nights, on June 26 and 27, 2019, at 9 p.m. ET in Miami, Florida at the Adrienne Arsht Center for the Performing Arts. For upcoming debates in general elections or later cycles such as 2024, the schedule can vary and debates are typically announced by the Democratic National Committee closer to the election year. If you're asking about the first Democratic debate for a different election cycle, please specify the year. For 2020, the first debate was June 26 and 27, 2019. Let me know if you want the date for a specific upcoming or past election cycle.
