How to read the moon calendar
Each day shows its date, the share of the Moon’s disc that is lit at noon, and the Moon’s shape that day. When a full moon, new moon or quarter falls on a day, it is named at the bottom of the cell.
Illumination is the part of the disc lit by the Sun. It grows from new moon to full moon (waxing) and shrinks from full moon to new moon (waning). Each day opens its own page with every signal for that date.

When is the full moon in July 1997?

When is the new moon in July 1997?

What do the percentages mean?
They show how much of the Moon’s disc is lit at noon. 0% is new moon, 100% is full moon and 50% is a quarter.
Why does another calendar give a different date?
A phase is a moment. When it falls near midnight, the date can differ by one day between time zones. This calendar uses Europe/Vilnius time for the days.
How often is there a full moon?
About every 29.5 days. Some months have two; the second is called a Blue Moon.
