How this is worked out

Each day shows the Moon at 12:00 noon UTC, drawn as seen from the northern hemisphere, computed with astronomy-engine, the same engine Sky checks against NASA JPL Horizons. The Moon's phase is the same everywhere at one instant, but the date changes with time zones, so close to a new or full moon your local day can differ. Alive uses your exact birth time and place, and it stays on your phone.
