The drawing shows the Moon as it is now, with the name of its phase. It is turned the right way up for your hemisphere, judged from your approximate location or from the place you chose for the planetary hours. Below it are the dates and times of the last new moon, the first quarter, the full moon, the third quarter, the next new moon and the next full moon. All of them are in your own time zone, and the ones already past are dimmed. Everything is worked out in your browser when you open the page, so it is always current.
A lunation, from new moon to new moon, takes about twenty-nine and a half days. The Moon waxes from new to full, passing the first quarter when half its face is lit, and wanes from full back to new through the third quarter. Many magical traditions time their work by it, choosing the waxing Moon for what should grow and the waning Moon for what should end.
