All moon phases at a glance.
From New Moon to Full Moon – all phases at a glance.
The moon calendar calculates the current lunar phase and the zodiac sign the Moon occupies each day of the month. The cycle runs from new moon through waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent — completing one full cycle (synodic month) in approximately 29.5 days.
The Moon changes zodiac sign every 2–3 days as it orbits Earth, and each sign is traditionally associated with different types of activity — from creative work to rest and reflection.
New moon: planting, beginning new projects. Waxing moon: growth, building momentum. Full moon: culmination, heightened energy. Waning moon: releasing, clearing, harvesting. These associations appear across British folk traditions, biodynamic farming, and modern wellness culture alike.
The exact dates are shown in the calendar above. Full moons occur roughly every 29.5 days. In the UK, full moons sometimes carry seasonal names from the Old Farmer's Almanac tradition — for example the Harvest Moon (September/October) and the Hunter's Moon (October/November).
Research is mixed. A 2013 study by the University of Basel observed shorter sleep duration and reduced deep sleep around the full moon. A 2021 study in Science Advances found synchronised sleep patterns tied to lunar phases across diverse populations. A direct causal link has not been conclusively established, but many people report lighter sleep during full moons.
Moon gardening is a well-established tradition in biodynamic agriculture (popularised in the UK by the Biodynamic Association). The basic rule: sow leafy and flowering plants during the waxing moon; harvest root vegetables and prune during the waning moon. Scientific evidence is limited, but many experienced gardeners report consistent results.
