How to Use the Moon Phase
Many people align important decisions with lunar cycles. New Moons are ideal for setting intentions and starting fresh projects. Full Moons bring things to completion and are powerful for releasing what no longer serves you. The Waxing phases support growth and building momentum, while Waning phases favor reflection and letting go.
Gardeners, manifestation practitioners, and astrology enthusiasts all use Moon phases to time their actions for maximum alignment with natural rhythms. Simply enter any date to check what the Moon was doing — or will be doing — on that day.
