Celtic Calendar with Tree Months (Moons) as Neo-Pagans See It

The Celtic Tree Calendar is a Neo-Pagan Calendar that claims to be based on the lunar cycle but is rather adjusted to the Gregorian calendar. If we insist to stay within 13 lunar months in a year we'll significantly fall out of sync in a couple of months and be totally lost within a year.

The History Behind the Celtic Tree Calendar

It is based on the Ogham alphabet, an Early Medieval alphabet used for the Irish language. The calendar was created by poet and historian Robert Graves in 1948, so it's actually a very new calendar and resembles very little with ancient druid calendars which were far more accurate from the cosmologic point of view.

Robert Graves used an old Song of Amergin as a starting point, translated it very loosely, and adapted the ancient Ogham alphabet with 15 consonants to 13 consonants only, so it could fit his theory of 13 lunar months in each solar year. Well, we all agree a solar year begins with a virtual starting point of the Sun related to the Eart and ends when the Sun 'reaches' the same point. This means one year has approximately 365,25 days as we all know from the Gregorian calendar. Even with three years with 365 days following by one leap year, we need some corrections from time to time, yet this calendar fits its purpose pretty well.

The lunar calendar, as presented by Robert Graves, has 13 months with 28 days and one additional day, which gives 13 x 28 + 1 = 365 days to each year. This effectively makes it a solar calendar (with the still unsolved problem of the leap year), so we can only look at it as a lovely quirk of an imaginative mind which became extremely popular among neo-pagans who are desperate to find meaning in the otherwise cynical and disappointing situation in the today's world without really looking for scientifically supported background.

Yet It's Cute!

Yes, the Celtic Tree Calendar is cute and can be used as an inspiration in our lives just like almost everything. So we will present it as the calendar created by Robert Graves and add a few interesting theories (developed from old druid teachings) for each month.

celtic tree calendar is based on magical properties of trees

As we already stated, there are 13 months in the Celtic Calendar and each one of them is devoted to a tree. Druids believed trees have magical powers. Even the word Druid is likely connected to 'duir' (meaning 'door', what is the name of one of the months) and derived from an old name for oak tree, meaning 'the one with the wisdom of the oak'.

Druids frequently used trees for gatherings, ceremonies, and meditation places. The Celtic Tree Astrology is based on Earth cycles and closely related to trees, which, in turn, were homes to dwarfs, fairies, and other magical beings.

Here are the months of the Celtic Tree Calendar:

Beth (Birch Moon) Dec 24 - Jan 20

This is the month of adaptability, ambition, elegance, rebirth, and regeneration.

Saille (Willow Moon) Apr 15 – May 12

The time of the Willow Moon is best for flexibility, healing, knowledge, rejuvenation, and nurturing. Willow protects against floods, storms, and other natural disasters, thanks to its connections to healing and growth.

Another important connection is the willow's connection to water and consequently to the Moon, which puts the tree in a realm of psychic ability and spirituality.

Ruis (Elder Moon) Nov 25 – Dec 22

This is the time of endings, great for creativity, regeneration, and rejuvenation. Elder is a symbol of prosperity. Its white flowers are good to repel insects, which was probably extrapolated to the belief of being able to protect against evil spirits.

Otherwise, a complete elder tree, from bark and roots to berries and flowers is traditionally associated with healing properties against at least 70 (!) health issues.

Special Day Dec 23

23 December roughly matches the Winter Solstice (21 December) and Christmas (25 December), which puts this date in the area of eight major Celtic holidays and also in the area of the major celebrations in all major religions (which, of course, are strongly intertwined with pagan celebrations, connected to life cycles). This is the day when the night is the longest (approximately) and the day shortest, which means it somehow resets the life cycle of the earth. While everything is dying, there's also hope for a new life, new beginnings, and purification. Some versions of the Celtic Tree Month Calendar put 23 December to the Elder Moon.
