Full Moon Calendar and 2025 Dates
The full moon cycle repeats roughly every 29.5 days, producing 12 or 13 full moons per year. In 2025, there are 13 full moons, which creates two occurrences of a single seasonal name and one Blue Moon full moon schedule 2025. The first full moon of 2025 lands on January 13, and the last occurs on December 4, with the midpoint cycle falling near the autumnal equinox full moon schedule 2025.
Each full moon is assigned a traditional name based on seasonal markers, Native American, Colonial American, and European sources. The January full moon is called the Wolf Moon, February hosts the Snow Moon, and March carries the Worm Moon. April's Pink Moon, May's Flower Moon, June's Strawberry Moon, July's Buck Moon, August's Sturgeon Moon, September's Harvest Moon, October's Hunter's Moon, November's Beaver Moon, and December's Cold Moon complete the standard 12-name cycle moon names origin.
Supermoons and Blue Moons in 2025
A supermoon occurs when a full moon coincides with lunar perigee, the closest point in the Moon's elliptical orbit. In 2025, supermoons are expected around October 6, November 5, and December 4, with the November 5 full moon widely cited as the closest and largest NASA Artemis lunar program. The October 6 full moon is also considered a supermoon by most standard definitions, and these three events form a consecutive supermoon trio in the final months of the year.
A Blue Moon is the second full moon in a single calendar month, and 2025 features one on August 31. Because August already has a full moon on August 1, the August 31 event qualifies as a seasonal Blue Moon under the most common modern definition. The next monthly Blue Moon will not occur until May 2026, making the August 2025 event the only one in the current 2025 calendar blue moon definition.
Cultural, Financial, and Market Relevance
Full moon dates influence retail, travel, and event-planning industries, with hotels, tour operators, and cultural festivals often aligning promotions with major lunar phases. The Harvest Moon in September and the Hunter's Moon in October historically mark peak periods for agricultural logistics, hunting seasons, and autumn tourism in North America and Europe. Companies in outdoor recreation, agritourism, and event management frequently reference these dates in seasonal marketing calendars.
Financial analysts and market historians have studied lunar cycles for potential effects on trading volume and volatility, though academic evidence remains mixed. Major exchanges such as the NYSE and Nasdaq operate on fixed calendars unrelated to lunar phases, but retail investor activity on platforms like Robinhood and trading communities on social media often spike around full moon dates. The SEC and financial regulators do not recognize lunar cycles as market-moving factors, and any perceived patterns are treated as behavioral phenomena rather than structural market drivers SEC investor education.
