The date "Mayday 20" could refer to different things depending on the context:
- May Day, the traditional festival, is celebrated on May 1st every year. It marks the beginning of summer and has ancient European origins with various traditional customs.
- Season 20 of the TV show "Mayday: Air Disaster" started airing on YouTube on June 5, 2025.
- Mayday Parade's 20-year celebration tour events are scheduled in 2025, such as on September 21 in Singapore and September 24 in Manila.
If the question is about the traditional May Day festival, it is on May 1. If "Mayday 20" refers to something else like a 20th event or series (e.g., the TV show or band anniversary), those are happening in 2025 but on different dates unrelated to the actual May Day festival date. Please specify if the interest is in the festival, the TV show season, or the band's 20th anniversary events for a more precise answer.
