What is Up With the Number 13 and Friday the 13th?

In 2020 there are 2 months that land on Friday the 13th – March and November.  (See end of article for more dates)

Some say, like the ancient Celtic and Norse peoples, 13 is a LUCKY number, and on Friday the 13th they took time to celebrate the Goddess because Friday is named after Freya the Norse name for Venus and 13 is her sacred number. So Friday the 13th was the perfect day to make love or do other ceremonies in honor of the Goddess.

For those who might not know – there are 5 Venus cycles that last about 19 months each – returning to a starting point every 8 years and in that 8 years Venus goes around the Sun 13 times. This links to the Fibonacci sequence: of 5, 8, 13 or  5 (Venus cycles) plus 8 (years) equals 13 circuits around the Sun. More on the current sacred Venus Journey 

Friday the 13th
As mentioned above Friday is Freya’s day (or the day linked with the planet Venus). This is about  Divine Feminine in her full power, great beauty, and where the Norse were concerned her ability to be victorious in battle, embracing death and rebirth. Freya (Venus) was accomplished in sorcery, as well as overseeing the mysteries of sexuality and fertility. Thus, Freya as Venus is a powerful expression of the divine feminine that comes to us from pre-patriarchal times, and many of her stories have survived into current times..

Guardian of thresholds Freya was called upon to assist in the passage through birth, orgasm, and death. She holds destiny in her hand and her sexuality is her power source.

On Freya’s most sacred day here are some questions to consider?
Do you actively seek pleasure?
Are you courageous and confident?
Are you in charge of you own destiny?
Do you accept yourself, approve of your self and respect yourself?
Do you LOVE who you are?
Do stand gracefully in your power and thus empower others?
Do you embrace your innate ability to manifest magic and beauty?

The Divine Feminine and the Number 13

For many 13 represents the return of the Divine Feminine including the mysteries connected with Mary Magdalene, Mother Mary, Shekinah and Sophia. 13 is linked to the natural rhythms and cycles of life that include sacred balance. 13 is also thought to be the essence of the empowered and embodied Christed Feminine.

The Power of 13
Some say 13 is a number that transcends matter and is coded with the frequencies of Ascension, Oneness and Unity that transforms all things. Since 13 is a prime number it is only divisible by itself representing purity – thus the number 13 is incorruptible and exists within its own integrity.

Turtle Numbers13 is linked with the Alpha and Omega, the beginning and the end. Many ancient secret societies and mystery schools understood that the number 13 represented death and rebirth through ascension into eternal life and it represented the secret knowledge of all life including sacred sexuality.

It is synchronistic that the 13th card in the Tarot is the Death card. The 13th rune in the Norse alphabet “Eiwaz” is also linked with the balance between light and dark, death and rebirth, the Heavens and the Underworld.

Turtles are considered to represent the ancient wisdom of the Earth, with 13 segments on their shells. Many believe this has to do with what is called the true Lunar Calendar. However, 13 is just one of the sacred numbers for the Moon along with 12, 19, and 29.5. More about the sacred numbers of the Moon HERE.

The Egyptians described 13 steps on the ladder that leads to eternity and the thirteenth step was where the soul reached the source of its self and attained spiritual completion. Interestingly, the word reincarnation has 13 letters.

In the Arthurian Legends Merlin guards the 13 Treasures of Britain. The Sacred Chord of the Druids had 13 segments and that there are 13 Doctrines of the Bards.

The United States and the Number 13

The flag of the United States of America has 13 horizontal stripes 6 white and 7 red and the original flag had 13 stars representing the 13 original colonies.

The U.S. Government Great Seal has 13 stars, 13 arrows, 13 berries, 13 stripes and 13 leaves, as well as two 13 letter phrases. For example: the Latin phrase on the Great Seal e pluribus unum has 13 letters and means “out of the many, one” or “one from many” or “many uniting into one”.

On the back of the Great Seal of the United States it says Annuit Cœptis. This phrase is take from the Latin words annuo meaning “to nod” or “to approve”, and coeptum meaning “commencement, or undertaking”. This phrase is literally translated as, “S/he approves of the undertakings” or “S/he has approved of the undertakings”. S/he refers to the Divine.

Magical 13
Some say 13 is a unifying vibration that activates the solar light body. Said another way it is the 12 around 1. The One is us and each One is integrating the twelve archetypes of the signs that when embodied and expressed through each of us is the 12 around 1 or 12 in the One.

Together the 12 in 1 becomes 13 and then we truly know the experience of Unity within the Diversity. We are the One who the twelve circle. So each One of us is essential to the whole as we make up the 1 in the number 13. After all Christ had 12 disciples so he himself was the 13th.

Over the years, the elite who hold the power of commerce, government, religious and educational institutions, etc. have successfully instilled fear around the number 13. It has been viewed as a most unlucky number when actually it is just the opposite.

Instilling fear of the number 13 was a way to disconnect the masses from this powerful divine source energy. It is time once again, to remember that the vibration of 13 helps us to realign with source energy and our own healing.

More on The Gregorian Calendar

The creation of the Gregorian calendar created a calendric system so precise in tracking the solar year it takes about 3,323 years for the calendar to drift off from the solar cycle one whole day. Wow…especially if you consider that the calendars we know of prior to this time drifted significantly over a much shorter time. In fact, Julius Caesar, had a calendar created and named after him, that reset the calendar by 10 days, because that is how far the calendric dates had drifted from the seasons.

Caesar’s calendar also began to drift. The Gregorian Calendar was created to solve this issue of the dates drifting away from the seasons they were created to represent. The Gregorian Calendar features a series of numbers, or dates, tracked by days, weeks and months. This calendar has become the global standard for determining what time it is.

The challenge is this calendar has also fixated humanity’s awareness to linear time and disconnected our awareness from cyclical time, time outside of time, multi-dimensional time and non-time. These are all forms of magical time that are not as available to us as they once were before our awareness was fixated on linear time.

Even so, the Gregorian Calendar does have a certain number magic connected to it that can create numeric portals that draw attention and our awareness to them. Over the last few years we have had dates like 11/11/11 or 12/12/12.  In 2014 we had the date 12/13/14. I myself love that I was born on 3/4/56.

So this brings us back to the Gregorian Calendar date of Friday the 13th, a date that was originally considered a fortunate time for honoring the Goddess on her special day. This practice was later vigorously discouraged by religious and political leaders who proclaimed both Friday and the number 13 together to be extremely unlucky. Discounting the traditions that still consider the number 13 as the number that bonds the 12 into one, or turns multiplicity into oneness or wholeness.

If you Truly Understand the Number 13

There is also an occult understanding of the number 13 that says if someone truly understands this number they will be empowered through the mysteries of completion. However, if the power of this number is misused it will have a destructive influence, hence the fear that has grown up around the number 13.

However, the number 13 is also thought to represent eternal love, totality, realization, and attainment.

13 has the honor of being the sixth prime number and one of the numbers in the Fibonacci sequence. The number 13 is also connected to the cycles of the Moon and the Earth. For example, the Moon averages about 13 degrees of movement per day. There are 13 weeks between a Solstice and Equinox or an Equinox and a Solstice. There are four seasons each year with 13 weeks in each season. 4 x 13 equals 52 weeks in a year.

The Playing Cards
This brings us to the playing cards (that are actually a calendar) having four suits – representing the four seasons and 13 cards in each suit for a total of 52 cards in the deck. Each card has an archetypal significance and can be read as book of destiny or a “Mystic Test Book”.

All of this suggests that 13 is far more important a number than we have been conditioned to believe.

  1. How beautiful. The significance of this looming full moon on 12/12 and the time of full moon is 12:12 from what I understand. Followed by Friday 13. Today I awoke, guided to the significance of today…. 12 days to solstice. “In the dark of the night, the light shines.’ my message from within..

    All morning it was sting in me 12 apostles, Jesus 13. They all symbolically represents an addict of Jesus. For me, Jesus born a man… Christed he became. 12 astrology signs each a piece of who I am in entirety 13 is the union of all as one within me. My birthday is 3/17… So much Pisces in my chart! Lol

    13 is to me creation, Divine mother…. This month now, if huge significance. Completion…. You see, I published my first book Soul 2 Soul through the experiences of a hospice nurse on Amazon last week. It is all about the love, oneness, connection of us all… And I love in southern USA with most of my patients African American living near the biggest slave port in history. But in publishing this… Now… Coming I guess my 12 aspects…. Alchemy, now 13… Divine, mastery, love, mother… So many words but I have no doubt, you know exactly what I mean.

    I googled importance of 12 into 13 and your web page showed up. Your page summed up EVERYTHING I just know/ understand. Even down to the turtles. Lol I have stopped about 6-8 times since May to rescue a turtle in the road.

    I know, my whole life, had prepared me for this month.

    Reading this page, just driving me deeper into the transformation at hand. Thank you!

    • Thank you so much for this…Ela Rae – I so get what you mean! AND I am a March (Pisces) birthday – so we share that. Love your insights and that we share the Turtle rescuing thing.

      Happy Full Moon, Solstice and High Holy Days!

  2. This is awesome information Cayelin, thank you. So important to dismantle the fear you mentioned about this 13 sacred number !
    Winks from the sky and earth: When I finished reading your article, I looked at the time and it was exactly 13:13
    13 infinite Blessings 🙂

    • I am chuckling with delight at the 13:13 synchronicity and thank you so much for your feedback. Yes its all about dismantling the fear of sooo much and especially the number 13. Today is August 31, 2019 turn the 31 around and its 13. How cool is that? Much love and gratitude to you Sonia for taking the time to share your thoughts! 🙂

  3. Loved reading this article about 13. It is my birthday on July 13th, with the Solar eclipse conjunct my Sun. I dreamed of a turtle in a riverbed and never knew of this connection to 13. Thank you.

    • Hope your birthday was magical Zoë…it has been a wild ride of a month for me. Good though intense. 🙂

    • Thank you so much for the link Kent. WOW

      I love the story and it is so synchronistic with what I shared about how Turtles have been showing up for me in the June Timings https://cayelincastell.com/2015-free-june-celestial-timings/ The end of the Cherokee story really confirms for me this thing I have for rescuing turtles from the road. 🙂

      From now on, when you see Brother Turtle crossing the road, remember what he is. If you can do so safely, stop and give him a little help just like the Eagle did long ago.

  4. “Some say Celtic and Norse people think 13 is a LUCKY number” your articles’ statement “What’s up with the number thirteen” gave me a sense of relief that all this old but new information is released into our thoughts in the year of 2015 once again as it has occurred in the past so be it in the present – and is it like that? ponder but can we know? And then, explore until we discover our true natures.

    Is the blue print available to further our evolutions? I wonder, ask, and ponder…to know – daily.

    So. thank you for your beautiful intent with content – so happy to have your honourable acquaintance and insights – Your information resonates with my perspectives of wholeness.

    A big thank you and Warm birthday wishes to you.

    Kindest Regards

    • Thank you so much Laurie for this wonderful feedback and I do believe the blueprint and pathway is available to us when we are tuned in to the unfolding mysteries of the cosmos, being informed by them and informing them through our thoughts, feelings and actions – especially when we are remembering to be grateful, and to at least intend to love ourselves, the Earth, each other and ALL life even if we aren’t always successful at doing that 🙂

  5. Wow, Cayelin, this is a fantastic compilation of so many wonderful aspects of 13! I’ve been a number 13 girl for most of my life, and I posted on my FB page about it today. Your article was a perfect follow up and I posted it on 2 of my pages as well! Blessings to you.
