What to look for in May 2027

May 2027 runs through 4 principal phases. The times listed are the instants the phases occur — the same moment everywhere on Earth, shown in your local time, which is why the date can differ from a calendar printed for another country.

Tides follow the same rhythm. Around the new and full moon the Sun and Moon pull in line and the tidal range is at its widest; around the quarters they work against each other and the range is at its narrowest. If you fish, dive or photograph a coastline, those are the dates that matter.

The illustration for each day shows how much of the disc is lit. It is drawn from the same calculation as the times, not chosen from a set of stock pictures, so a day at 63 percent looks like 63 percent.

Frequently asked questions

When is the full moon in May 2027?

On the 20th. The exact time appears above in your own time zone — the instant is the same worldwide, but the local date can shift by a day depending on where you are.

When is the new moon in May 2027?

On the 6th. New moon is the darkest sky of the month, which makes those nights the best for seeing faint stars.

Why do the times differ from another site?

Usually because the other site shows Universal Time and this page shows yours. A phase at 23:40 UTC is already the next day across much of Europe and Asia. Our times come from the algorithm in chapter 49 of Meeus and are checked against the US Naval Observatory.
