Overview

• The May full moon, known as 'Wonnemond' in Germany and 'Blumenmond' among Indigenous North American groups, will peak on May 12, 2025, at 18:55 UTC.
• The moon will rise around 21:15 local time and set near 5:30 the following morning, offering a full night of visibility.
• The term 'Wonnemond' originates from Middle High German, reflecting the joy and renewal of nature in spring, while 'Blumenmond' highlights the bloom of plants during this season.
• These traditional names, while culturally significant, hold no formal astronomical relevance, as full moons are defined by the Moon's complete illumination by the Sun.
• Although the full moon influences the ecclesiastical calendar for Easter, scientific studies have yet to confirm any direct impact on human sleep patterns.
