This calendar is the working calendar of Hellenion, a diverse
group of Hellenic polytheists sharing the common goal of living
a life of piety and proper respect for the Gods of Olympos and
ancient Hellenic tradition.
The calendar is based on the monthly and annual observances and
festivals of the ancient Athenians from about 800 BCE to 323
BCE. This version was created using information derived from
www.numachi.com/~ccount/hmepa and from
http://aa.usno.navy.mil/data/docs/MoonPhase.html as well as
This calendar is a work in progress, and as research and
reconstruction proceeds, the calendars of future years will
reflect this. The on-line version of this calendar, contains
links to descriptions of all the special days noted on this
calendar and suggestions about how to observe them in the 21st
You are under no obligation to observe all the occasions and
days mentioned here; in fact, that would be all but impossible
at present, since none of us live in a wholly polytheistic city.
Every observance is optional. This calendar is made available to
you as a learning tool, and as a framework to begin or extend
your practice of ancient Hellenic religious tradition. Needless
to say, ancient Hellenic religion involved many more practices
than are implied by the calendar.
The calendar outlines ancient monthly practices, such as
Hekate’s Deipnon (on the darkest night, honoring Hekate,
the “Bringer of Light”, by a donation of food at a crossroads or
to a charity), Noumenia (new moon, beginning of
the new Athenian month) and the Agathos Daimon (honoring one’s
own personal spirit, a destiny, a characteristic, a blessing,
inherently neither good nor bad). It also lists
ancient Athenian festivals, on the exact dates where these are
known. Where the exact date has not been revealed by research, a
question mark follows the name of the festival. Information
specific observance can be found in the references mentioned
above. Note that the date of the new moon is determined by when
the crescent is visible in Athens; check local sources for the
exact time and day in your locality if you wish to be precise.
In addition to ancient festivals and observances, certain modern
occasions are listed as well. This includes the Hellenion
monthly libation (ensuring that at least one day a month is
shared by a community, albeit scattered, at the same time, and
also ensuring that each of the twelve Olympians is honored at
least once during the year). Note that this libation is not an
official practice of Hellenion but a voluntary activity endorsed
by many Hellenion members.
Some modern festivals are also listed, such as Heliogenna, held
over several days during the shortest days of December, and
Prometheia, held in Greece on the summer solstice near Mt.

Remember that, among the ancient Greeks, the day begins at
sundown of the previous day. Days in gray indicate days observed
by Hellenion members, including new moon/beginning of Greek
month and Hellenion monthly libation.

“y” to represent the short “u” of Greek, “kh” is used to
represent “chi” (χ), a sound which does not exist in English,
