The forgotten September 29 feast where St. Michael, harvest customs, quarter days, blackberries and the coming dark meet.

There’s a strange little holiday sitting at the end of September that most of us barely notice anymore.

It arrives one week after the Autumn Equinox, when the light is visibly changing. Gardens are slowing down. The nights suddenly feel like nights again. In older farming communities, the harvest was nearing its end and winter was no longer some distant problem for Future You.

September 29 is Michaelmas.

Officially, Michaelmas is the Feast of St. Michael and All Angels, an old Christian feast honoring the Archangel Michael. But leave it to centuries of farmers, tenants, cooks, gardeners and storytellers to turn a church feast into something much bigger.

Michaelmas became a hinge in the year.

Rents came due. Workers changed employment. Fairs were held. Geese went into the roasting pan. In parts of Scotland, special harvest cakes were baked. Michaelmas daisies flowered just as much of the garden was fading.

And somewhere in the brambles, according to folklore, either the Devil or the púca was busy ruining the last blackberries of the season. (Not kidding. Read Why the Devil Spits on Blackberries After Michaelmas: Folklore & Magic of September 29 to learn more. It’s wild.)

So, yes. A lot going on here.

OK, What Is Michaelmas?

Michaelmas is celebrated on September 29 in honor of St. Michael the Archangel and, in the Western Christian tradition, the wider company of angels.

The name is wonderfully straightforward. Michaelmas essentially means the Mass or feast of Michael, in the same way that Christmas developed from Christ’s Mass.

The feast itself is old, but what makes Michaelmas especially interesting is what happened around it.

Because September 29 falls shortly after the Autumn Equinox, Michaelmas landed at an extremely useful point in the agricultural year.

By late September, major grain harvests in much of Britain were traditionally expected to be largely finished. Livestock decisions loomed. Stored food mattered more. The productive part of the year was giving way to the colder season.

Over time, the religious calendar and the working calendar became tangled together.

That happened constantly in traditional cultures. A saint’s day might also tell you when to sow something, hire somebody, collect rent, stop eating a particular wild fruit or expect the weather to turn.

The calendar wasn’t decoration. It organized life. (Roud, 2006; Hutton, 1996)

So, Who Is St. Michael?

Michael is one of the few angels actually named in the biblical tradition.

He appears in the Book of Daniel as a powerful heavenly protector. The Epistle of Jude calls him an archangel, while the Book of Revelation gives us the image that would define much of his later iconography: Michael leading the heavenly host against the dragon.

That image stuck.

For centuries, Michael has been depicted armed, often carrying a sword or spear. Sometimes he stands over a dragon or serpent. In other images he holds scales, reflecting his later association with weighing souls.

Michael also exists beyond Christianity. His roots lie in Jewish tradition, and the angel known as Mika’il appears within Islam.

His name is traditionally understood from Hebrew as a question: Who is like God?

But you don’t have to approach Michaelmas devotionally to understand why this particular figure became so compelling at this particular point in the year.

Look at the season.

The days are getting shorter. The fields are emptying. Winter is coming. And right there at the gate stands an enormous winged being with a sword.

Subtle, not so much.

Michaelmas and the Coming Dark Season

This is the part of Michaelmas I find especially interesting.

The feast arrives during one of the fastest visible changes in the solar year. After the Autumn Equinox, darkness gains ground quickly in the Northern Hemisphere. Sunset begins creeping noticeably earlier. Plants withdraw. Animals change their behavior. Humans start moving more of their life indoors.

Our ancestors obviously didn’t need an app to tell them the photoperiod was shrinking. They could see it.

Michael’s traditional role as a defender made him an almost perfect symbolic figure for this threshold. The spiritual imagery of protection sits beside the physical reality of preparing for a harder season.

Religious feast days became embedded in agricultural life because people lived according to both calendars at once. The sacred calendar told stories about saints and angels. The land told you whether the grain was dry, how much fodder remained and whether the household had enough put by for winter.

Eventually, those stories begin talking to each other. (Hutton, 1996; Roud, 2006)

Michaelmas Was Basically a Deadline

Michaelmas wasn’t just symbolic. It was administrative, if you think about it.

In England, September 29 became one of the traditional quarter days, alongside Lady Day in March, Midsummer in June and Christmas in December.

Quarter days divided the year into practical chunks. Rents could fall due. Leases began or ended. Accounts were settled. Agricultural employment contracts changed. Fairs and hiring gatherings clustered around these turning points.

For a tenant farmer, Michaelmas could therefore carry considerably more emotional weight than a pretty seasonal festival.

Imagine harvest ending and your rent being due at the same time. Festive, right?

Historical work on English agricultural rents shows Michaelmas and Lady Day were particularly important payment dates for farmers. The day could mark the difference between beginning the next season securely and facing very real financial trouble.

Michaelmas also lent its name to legal and university terms, traces of which survive today.

The old seasonal calendar wasn’t simply about observing nature. It created moments when unfinished business had to become finished business.

There’s something about that I rather like. Not the landlord part. But the reckoning.

The Strange Story of Old Michaelmas Day

And then Britain changed its calendar. (I mean, stop with all the calendar nonsense already!)

In 1752, Britain and its dominions adopted the Gregorian calendar and omitted eleven dates from September. September 2 was followed by September 14.

The feast of Michaelmas continued to be celebrated on September 29.

But some older fairs, hiring customs and seasonal practices had effectively been tied to where Michaelmas fell within the natural year rather than to the number printed on the calendar.

So another date survived in folk custom: October 10, Old Michaelmas Day.

This is one reason Michaelmas folklore can get confusing. You may find one tradition attached to September 29 and another insisting that the crucial date is October 10.

Both can be right within their own historical context.

Old Michaelmas is also particularly relevant when we get to the blackberries. (Because of course we have to talk about the blackberries.)

Why You Weren’t Supposed to Eat Blackberries After Michaelmas

Across Irish and British folklore, people were warned not to pick or eat blackberries after Michaelmas. The explanation varies a ton.

In some versions, the Devil fell from heaven into a blackberry bush and was so furious about it that he spat on the fruit. Elsewhere, he cursed them. (Read that whole crazy story here.)

Irish folklore sometimes hands the job to the púca, the unpredictable supernatural being of Irish tradition, who fouls or claims the blackberries after the appointed date.

Folklore collected in Ireland during the twentieth century repeatedly records warnings that blackberries shouldn’t be eaten after Michaelmas. Some folks even explained the practical wisdom underneath the supernatural story: By this time of year, the berries were deteriorating and no longer considered good to eat.

So, the old rule may have functioned as both folklore and seasonal food knowledge. Which is exactly the kind of thing I love.

Tell a child that late blackberries might be moldy and you’ll get approximately nowhere.

Tell them a púca has been doing unspeakable things to the bramble patch? Message received. (Danaher, 1972)

Why Folks Ate Goose on Michaelmas

If blackberries were leaving the menu, that meant that goose was arriving.

Michaelmas became strongly associated with eating roast goose in England and Ireland.

This made practical agricultural sense. Geese could be turned into harvested fields to feed on fallen grain and stubble after the crop had been gathered. By late September they were nicely fattened.

Hence the Michaelmas goose or stubble goose.

Eating one also became associated with prosperity. An old belief held that having goose at Michaelmas would help protect the household from financial want during the coming year.

Considering that rent might also be due, this isn’t really surprising.

There are later stories involving Queen Elizabeth I and a Michaelmas goose, but the custom doesn’t need a royal origin story to make sense. The agricultural calendar already explains a lot.

The fields had given what they were going to give. The bird had fattened on what remained. Now it fed the household. That’s harvest logic in its purest form. (Roud, 2006; Simpson & Roud, 2000)

The Michaelmas Daisy: A Flower at the Edge of Winter

Then there are the flowers.

Several late-blooming asters became commonly known as Michaelmas daisies because they flower right around the feast at the end of September.

They’re exactly the sort of plant that becomes meaningful without anyone needing to work very hard at symbolism.

By Michaelmas, much of the garden is winding down. Leaves are beginning to turn. Summer flowers are disappearing.

And then there are asters. Purple, blue, pink and white, still blooming.

They became associated with St. Michael partly because of their timing, but it’s easy to see how they gathered broader meanings of endurance and protection as well. They bring color precisely when the landscape begins moving toward dormancy.

The symbolism almost writes itself.

Not immortality. Not pretending winter isn’t coming. Just life continuing at the edge of change. (Vickery, 1995)

Michaelmas in the Scottish Highlands

Some of the richest Michaelmas customs were recorded in the Scottish Highlands and Hebrides.

Folklorist Alexander Carmichael documented elaborate traditions surrounding St. Michael’s Day in Carmina Gadelica, his great collection of Gaelic prayers, charms and customs gathered primarily in nineteenth-century Scotland.

One of the best known is the struan, or struan Micheil, a special Michaelmas cake made from the grains grown on the family’s land.

Carmichael describes Michaelmas Eve as a busy threshold filled with food preparation and household ritual. Struan was baked, carrots were gathered, and the following day could involve worship, visiting burial grounds and community festivities.

The surviving descriptions are fascinating because Michaelmas here feels neither purely agricultural nor purely Christian.

It more belongs to the household.

The year’s grain becomes bread. Family memory becomes part of the feast. Seasonal abundance gets acknowledged before winter narrows the world again.

That said, Carmichael’s accounts need to be read with the usual care given to nineteenth-century folklore collections. They reflect his informants, his era and his own editorial hand.

Still, they preserve a remarkable picture of Michaelmas as a living seasonal celebration rather than simply a date on a church calendar. (Carmichael, 1900)

The Harvest Is Over. Now What?

This may be the deeper reason Michaelmas still feels relevant.

Harvest festivals usually focus on abundance. Look what grew, what we gathered, and what we have.

Michaelmas asks a slightly different question. Is it enough?

Because once harvest ends, you can’t keep pretending there’s unlimited time to prepare.

You have what came in from the field, what’s stored, and what still needs repairing before cold weather.

The season has shifted from expansion toward preservation.

That creates a natural moment of assessment.

Traditional Michaelmas customs reflected it materially through rent days and changing employment. The symbolism of Michael adds another layer. And that’s to discern what needs defending as you cross into the darker part of the year.

Not everything needs to come with you or deserves access to your energy. And not every unfinished obligation should be allowed to trail behind you indefinitely. (There’s a sword in Michael’s hand for a reason.)

Michaelmas as a Day of Protection

Michael eventually became one of the great protective figures of Western religious and folk tradition.

That protection can be understood literally within devotional Christianity, where Michael is invoked as an angelic defender.

But the archetype travels remarkably well.

Michael isn’t hiding from darkness. He’s meeting it at the boundary. There’s a meaningful difference.

Seasonal spirituality can sometimes get a little too obsessed with light. We want candles and sunshine and triumphant metaphors about chasing darkness away.

Nature doesn’t chase autumn away. It enters and rolls with it.

Michaelmas offers another model. Acknowledge that the dark season is coming, then decide how you want to cross its threshold.

How to Celebrate Michaelmas Today

You don’t need to recreate a medieval feast or suddenly acquire a goose.

(I roasted a goose once for my food blog, The Hungry Mouse, and man, that was a situation. It was delicious, but made an unholy mess in the oven. If you cook, def check out my post to learn from my mistakes.)

So, a modern Michaelmas practice can be beautifully simple. Try this.

Go outside around September 29 and actually look at what the land around you is doing. Notice what’s still blooming. Look at what’s gone to seed. See what the trees are beginning to withdraw.

Then turn that attention toward your own household.

Ask yourself: What needs finishing before the season changes further?

This is a good time to settle something you’ve allowed to linger. Pay an overdue obligation if you can. Clear an entranceway. Repair the thing you’ve been walking past for six months pretending not to see.

You can also work intentionally with protection.

Light a candle near your doorway. Place an image of Michael on an altar if that tradition speaks to you. Use a sword or picture of one (tarot cards work well here, and they’re relatively small), a piece of iron or another personal symbol of boundary and discernment.

You might ask: What am I protecting as I move into the darker half of the year?

Then ask the harder version: What am I no longer obligated to protect?

Those answers may not be the same. And that’s OK.

For a more harvest-centered observance, bake bread with local grain if you can get it. Cook something seasonal. Bring Michaelmas daisies or other late flowers into the house if you grow them.

And if you’re walking past a blackberry bramble? Well. Check the date.

The Forgotten Threshold Between Equinox and Samhain

Michaelmas occupies an interesting space in our modern seasonal imagination.

The Autumn Equinox gets plenty of attention. Samhain and Halloween practically own late October.

But between them lies September 29. Michaelmas.

A day when the harvest was supposed to be ending and accounts came due. A day of roast goose and late flowers. A day associated with contracts changing hands and workers packing their belongings for somewhere new.

A feast dedicated to a protector appears just as the year moves decisively toward darkness.

You don’t have to share the religious worldview that created Michaelmas to recognize the power of that placement.

The old seasonal calendar was full of moments like this. Not every threshold required a solstice. Sometimes people simply knew that the field was empty, the rent was due and winter was coming.

And that was enough to make a day sacred.
