Next Full Moon?

Full moon names — the complete list

Each full moon of the year carries a traditional name, mostly derived from Native American Algonquin tribes and adopted by Colonial American settlers. January's Wolf Moon was named for the howling wolves heard on winter nights. February's Snow Moon reflects typical winter conditions. March's Worm Moon marks the thawing of ground as worms return. April's Pink Moon takes its name not from colour but from the pink phlox wildflower that blooms in early spring. May's Flower Moon and June's Strawberry Moon continue the seasonal theme. July's Buck Moon coincides with male deer beginning to regrow antlers. August's Sturgeon Moon was named by tribes that fished the Great Lakes. The September or October Harvest Moon is the most famous, followed by the Hunter's Moon. November's Beaver Moon and December's Cold Moon complete the calendar.

How is the full moon date calculated?

The dates on this page are computed using the Meeus lunar algorithm, which models the Moon's orbital mechanics with high precision. The lunar cycle is approximately 29 days, 12 hours, 44 minutes and 3 seconds — not exactly 29.5 days. This fractional difference accumulates over time, which is why full moon dates shift across the calendar year and why the same date rarely sees a full moon two years running. The algorithm accounts for the gravitational influences of the Sun and planets on the Moon's orbit, producing predictions accurate to within a few minutes.

Does the full moon really affect human behaviour?

The idea that the full moon influences human behaviour is one of the most persistent beliefs in folklore. Emergency services and healthcare workers often report busier nights during full moons. However, controlled scientific studies have consistently failed to find a statistically significant link between full moon phases and hospital admissions, crime rates, births or mental health episodes. The most likely explanation for the persistent belief is confirmation bias — we notice and remember the busy full moon nights and forget the quiet ones. The Moon's gravitational effect on large bodies of water (tides) is real and measurable, but the human body contains too little water in any contiguous body for tidal forces to have physiological effects.
