Mini Season – Autumn Equinox

Gone are the birds that were our summer guests,
With the last sheaves return the laboring wains!
All things are symbols: the external shows
Of Nature have their image in the mind
As flowers and fruits and falling of the leaves
The song-birds leave us at summer’s close,
Only the empty nests are left behind,
And the pipings of the quail amid the sheaves
(Excerpt from The Harvest Moon by Henry Wadsworth Longfellow)

Henry Wadsworth Longfellow’s (1807-1882) poem “The Harvest Moon” provides us with the perfect introduction for the mini season of Autumn Equinox.   

The Autumn Equinox

The mini season of Autumn Equinox runs from September 22 until October 7. The mini seasons were originally created by the ancient Chinese and then adapted by the Japanese in 1685. (1

Each mini season is made up of three micro-seasons.  The micro-seasons for the Autumn Equinox are:

  1. Thunder lowers it voice (Sep. 22- Sep 27)
  2. Hibernating creatures close their doors (Sep. 28- Oct 2)
  3. The paddy water is first drained (Oct 3-  -Oct 7)

The mini season prior to Autumn Equinox was called White Dew (Sept 7 – Sep 21) and the following season will be Cold Dew (Oct 8 – Oct 22).  As you can tell by the names of these seasons, we are shifting into the colder months.

The autumn equinox marks the time when the length of day equals the length of night.  It is at that moment that ‘the Sun crosses what we call the ‘“celestial equator’—an imaginary extension of Earth’s equator line into space.”(2) This year the equinox occurred on Wednesday, September 22, 2021, at 3:20 PM. 

The autumnal equinox also marks the beginning of autumn.  Autumn will last until the winter solstice on December 21.  

On September 20, just two days prior to the autumn equinox, we had the harvest moon.  The harvest moon is the full moon that occurs closest to the autumn equinox. Because of this, the harvest moon has the potential to happen in either September or October.  This year seems slightly special because the harvest moon and the equinox are so close together. 

The Harvest Moon and Haiku

The equinox and the harvest moon are kigos, or seasonal words, used in writing haiku. (We explored the kigo in the post about the mini season of White Dew.) Other words associated with this season as suggested by the producers of Season by Season include:

Harvest, the Green Corn Ceremony, giving thanks, apple cider and apple “bees”, Corn Spirit and other folklore about the harvest including: The stranger, The Maiden, The Witch, The Old Woman.  Corn spirit animals, and John Barleycorn.

From my personal experience, I might add the haying of fields, daddy longlegs spiders, and mushrooms. 

Since the harvest moon is such a prominent experience for this mini season, it seems fitting to focus our attention on haiku that highlight this event. The following haikus are written by some of the early masters of the haiku tradition.

Yosa Buson 1716–1784

A bright harvest moon —
rainwater has collected
on the surface of the pond
Since it turns out
I’m all by myself
I make friends with the harvest moon

Kobayashi Issa (1763–1828)

mountain village--
even in my soup
the harvest moon

harvest moon--
sitting cross-legged
like Buddha

Basho (1644–1694)

Harvest moon:
around the pond I wander
and the night is gone.

Hattori Ransetsu (1654-1707)

Under the harvest moon
Smoke drifts
across the lake

(Hattori Ransetsu was an Edo Samurai who became a haiku poet and studied under Basho.)

If you happen to have any other favorite haiku that might fit this season, feel free to share. 

The Harvest and Song

Are interested in the role music plays in the traditional harvest?

The producers of the Season By Season podcast have released another great episode, and this time Alexis and Kit talk with Annie Patterson and Peter Blood of “Rise Up & Sing” to discuss the songs and music of the harvest season.  If you have a moment check out their podcast.

  1. I never knew this about mini seasons, it is certainly the season if cold dew in the meadow here, my shoes are soaked after any morning walk. It feels like earth is breathing in the humidity that makes late summer here so soupy. It feeds the great renewal, I guess.

    1. The mini seasons are definitely an interesting way to track the yearly changes. I find that just thinking about things this way makes me pay more attention to what is happening in the world around me. I am glad that you enjoyed the post!

  2. I’m following the 72 Seasons App too! It’s fascinating, I love it, and it’s thanks to you for introducing me to it! Have a great weekend! 🙋‍♂️

    1. Hi Ashley, Great to hear you got the app. They have some interesting stuff there. I am wondering if they will change up some of the content when the year starts over. Maybe new haikus or commentary? Thanks and have a good weekend!

  3. I think that, after today, I will always associate the autumn equinox with the rats’ picnic. When I was out with the dogs, I was watching them scurrying about the edge of a field, gathering left-over grains and dashing back into the hedgerow. I’ve never seen so many rats at the one time! Just as well I like rats. 🙂
