An eclipse's time is the moment of greatest eclipse. A lunar eclipse can be seen from anywhere the Moon is above the horizon at the time. A penumbral eclipse only dims the Moon slightly, so it's easy to miss with the naked eye. An annular solar eclipse shows its ring of fire only along the narrow path the Moon's shadow crosses; across a much wider area around it, it appears partial. Not every eclipse is visible from the US.

The zodiac sign in the table is where the Moon stands at noon. The Moon changes sign every two to two and a half days, so by the exact moment of a new moon, quarter or full moon it may already be in the next sign. For the phases themselves we give the sign at that exact moment.
