Moon phases

Moon phases are astronomical moments that describe how much of the lunar surface is illuminated and visible from Earth. This hub gives quick access to the yearly calendar, month filtering, and short explanations of the key phases. Times are indicative and can vary slightly by timezone, rounding, and source conventions. For a broad view, use the yearly page; for detailed planning, open the month you need. Treat this as a practical guide rather than an exact measurement tool for critical activities.
