are full moons the same date everywhere
The answer? Yes. The Moon, of course, orbits the Earth, which in turn orbits the Sun. The peak of the Full Moon is when the Moon is opposite the Sun â 180 degrees away. Therefore the Full Moon (and the other moon phases) occur at the same time, regardless of where you are located on Earth. The reason why I give different times and dates for the New and Full Moon phases (in my e-letter, which you can sign up for here) is because of timezones.
