The moon icon indicates the current phase. The applets is also computing the
duration of lunations, i.e the time interval
between successive New Moons. In addition the
right column is showing the difference between the
duration of that lunation and the mean value of 29
days, 12 hours, 44 minutes (29.5306 days). You may use the key
"y" to increase the year, or shift key and "y" to
decrease the year.

Biggest and smallest Full Moon
A Blue Moon
is the second full moon in a calendar
month. Usually months have only one
full moon, but occasionally a second
one sneaks in. Full moons are
separated by 29 days, while most
months are 30 or 31 days long; so it
is possible to fit two full moons in a
single month. This happens every two
and a half years, on average.
