blue moon haunted house

On August 30/31, 2023, a Blue Moon will shine brightly in the night sky.

The historical origins of the term are shrouded in a bit of mystery and, by many accounts, an interpretation error.

Some believe that the term “blue moon” meaning something rare may have originated from when smoke and ashes after a volcanic eruption turned the Moon blue. Others trace the term's origin to over 400 years ago—folklorist Philip Hiscock has suggested that invoking the Blue Moon once meant that something was absurd and would never happen.
