when blue moon appears in 2023

The Blue Moon in 2023 appeared on August 30-31. It was the second full moon in August, known as a "monthly Blue Moon," and it coincided with a Supermoon, meaning the moon was near its closest point to Earth, making it appear larger and brighter. The exact moment of the full Blue Moon was at 9:36 p.m. EDT on August 30 (or 03:36 GMT on August 31), and it rose just after sunset around 7:10 p.m. EDT, setting just before sunrise on August 31.
