Rare Blue Moon to appear May 31, 2026

By PulseAugur Editorial · [1 sources] ·

A rare monthly Blue Moon is set to occur on Sunday, May 31, 2026. This phenomenon happens when a full moon falls for the second time within a single calendar month, a result of the moon's 29.5-day cycle not aligning perfectly with our longer calendar months. Despite its name, the moon will not appear blue; instead, it may exhibit an orange hue during moonrise due to atmospheric light scattering. The next such monthly Blue Moon will be visible on December 31, 2028. AI
