According to the popular and more recent definition, a Blue Moon is
the second Full Moon to occur in a single calendar month. There
have been other, older definitions but this is the one that seems
to have stuck.
Two Blue Moons in a year happens usually once in about every 19
years. There were two blue moons in 1991. However, because the
timing does not quite work out in 2029 the next time we see two
will be in 2048.
2010
Australia, New Zealand and the Far East are the only areas to have
a double Blue Moon this year. For the rest of the world the Full
Moon that occurred in 1 Jan 2010 AEST was for them in the evening
of 31 Dec 2009. They got a Dec 31 Blue Moon, we got a Jan 30 Blue
Moon and TWO Blue Moons in a Calendar Year (Jan 30 and Mar 30). Now
isn’t that kind of special?

path just a short walk from a car park. I managed to squeeze in a
logbook and pencil but there’s not much room for swaps. Please
rehide it as you found it.
