There are several obvious sites/sources that list FULL MOON
DATES+TIMES for Washington, CT 06794 and indeed MOON RISE TIMES for
that locale as well, but they don't always seem to coordinate for a
person who wants to know exactly when and how long to howl. What is the
WINDOW OF TIME in which I can stand in my weed field and look up to
see a FULL MOON EVERY MONTH IN 2003+2004?

Dear jhh,

There is a small problem. Since Moon and Earth are in perpetual,
gliding motion and not moving step-by-step like a cogwheel mechanism,
real Full Moon is - technically spoken - lasting only a very short
moment of time. The second before, the Moon is still waxing. The
second after, she's waning again. There is no definite time window
during which the Moon remains absolutely full, everything proceeds and
changes without pausing. You might, for your own purposes, define the
whole time between Moonrise and Moonset of a Full Moon night as your
time window. But in astronomical terms, this would not be a constant
Full Moon phase.

Best regards,

What sites and sources have you tried?  This information would be
useful for two reasons: 1) so that we do not propose those sites or
sources as an answer, and 2) so that we can evaluate what the problems
were with those sites and sources were, and thus find better ones.

Do you need to know exactly what time the moon becomes full -- in
other words, has just finished waxing and is just about to wane?  Or
would you accept a certain amount of imprecision, such as "between
time X and time Y on this date, a full moon [not in the precise sense
that scriptor noted, but rather in the common definition] will be out
in Washington, CT"?

Hello jhh-ga,

I have located the following software for you :


Moontool 2.0

From the developer: "Calculates the current moon phase together with
several other astronomical data, like the distance of the sun and the
moon, the rise and set, equinixes and solstices, eclipses. Also
calculates moon-related holidays like easter, pesach, chinese new
year. Full source code (Delphi) available at webpage."


This free software tool gives you the precise time (to the minute) at
which the full moon is at its peak, for a given location (you can
enter your latitude and longitude coordinates). You can also enter any
calendar date and the program will show you the full moon time/date
for the given month. Julian and regular dates are accepted.

Other information includes the age of the moon, moon phase in
percentage, moon's distance, moon subtends, sun's distance, sun
subtends, last new moon, first quarter, last quarter and next new

I would have to agree with Scriptor that there is no real "window" of
time for a full moon, only a peak instant when the moon is at its
"fullest". This tool provides this information, for any given month
and year you enter.

I hope this is what you are looking for, and constitutes a
satisfactory answer. If you need further information or clarification,
please do not hesitate to post a Request For Clarification and I will
be happy to assist further.

Thank you for using Google Answers and enjoy your free software!
