The History of Saying "March Comes in Like a Lion"

You can hear it in a school hallway, a grocery store checkout line, or a group chat: someone looks out the window, shakes their head, and says, “March comes in like a lion.” It sounds ancient and obvious—like it must have been said forever. But the phrase has a surprisingly traceable past, and it didn’t start as a cute way to complain about a rough start to the month.

A saying that feels older than it is

“March comes in like a lion and goes out like a lamb” is one of those lines people treat like a timeless proverb. In reality, the version most Americans know took shape in English only a few centuries ago, and it likely grew from a mix of old calendar habits, religious timekeeping, and even the night sky.

The saying stuck because it does two jobs at once. It gives people a simple story about a month that often feels unpredictable, and it offers a hopeful promise: whatever starts fierce might end gentle.

What the phrase actually means

The basic idea is contrast:

• “In like a lion” suggests a loud, forceful beginning—something intense, unruly, or dramatic.
• “Out like a lamb” suggests a softer ending—calmer, quieter, and more pleasant.

Even if you’ve never thought about it, the phrase is built like a tiny fable. Lions and lambs are instantly recognizable symbols: power versus innocence, chaos versus calm. That makes the saying easy to remember and easy to reuse in everyday talk.

People also flip it around—“in like a lamb, out like a lion”—to describe the opposite pattern. That flexibility helped the saying survive.

The English roots: proverbs, almanacs, and rhyme

The lion-and-lamb pairing shows up in English writing at least as far back as the 1600s. One commonly cited early source is John Fletcher’s play The Woman’s Prize (performed in the early 1600s), which includes a line close to the idea: March is described as beginning like a lion and ending like a lamb.

That matters because it shows the thought was already familiar enough to use in a play. It wasn’t explained to the audience. It was dropped in as something people would “get.”

Later, the wording spread through proverb collections and almanacs. Almanacs were a big deal in early modern Britain and colonial America. They weren’t just about dates. They mixed practical advice, jokes, moral lessons, and short sayings people could repeat. A phrase like this fits perfectly: short, punchy, and tied to the calendar.

Once a saying becomes a rhyme, it becomes sticky. You don’t need to remember where you heard it. You just remember it.

Why a lion and a lamb?

The animal choices weren’t random.

The lion: a ready-made symbol of force

In European storytelling, the lion had long been the “king” figure—strong, loud, and hard to ignore. Calling something “lion-like” instantly signals intensity.

The lamb: gentleness with religious echoes

The lamb is a symbol of softness and innocence, but it also carries religious meaning in Christian culture. “The Lamb of God” is a major image in church language and art. Even if the proverb wasn’t meant as a religious statement, the lamb would have felt familiar and meaningful to English speakers for centuries.

Put them together and you get a sharp contrast that almost explains itself.

A second origin story: the sky, not the street

There’s another explanation that often gets mentioned, and it’s worth knowing because it shows how people connect sayings to different kinds of “signs.”

Some link the “lion” to the constellation Leo and the “lamb” to Aries (the ram). The idea is that the month’s beginning and end align with different zodiac signs, so March “comes in” under one symbol and “goes out” under another.

This explanation is popular, but it’s messy as history. Aries is a ram, not a lamb, and the zodiac dates don’t line up neatly with the whole month in a simple way. Still, the fact that people reach for the stars to explain the proverb tells you something: humans love giving tidy stories to complicated patterns.

The more grounded origin is the English proverb tradition. The zodiac link is more like a later “folk explanation” that makes the line feel even older.

How the saying traveled and took hold in America

When English settlers came to North America, they brought their sayings with them. Over time, “in like a lion, out like a lamb” became a standard line in American speech, especially in places where people leaned on almanacs, farming calendars, and local lore to plan work and travel.

It also became a classroom favorite. Teachers used it to introduce:

• idioms and figurative language
• similes (“like a lion”)
• how proverbs reflect culture

Once something becomes part of school memory, it gets passed on almost automatically.

The phrase’s real power: it’s a pattern people want to believe

A big reason the saying survives is psychological, not historical. It offers a comforting structure:

• If the beginning is rough, the ending might be better.
• If things start gently, be ready for a twist.

That’s not just about one month. People use the phrase as a general metaphor for life. You’ll hear it in workplaces during a stressful project kickoff, or in sports when a team starts aggressively and then relaxes.

It’s a way to talk about change without sounding dramatic. The animals do the emotional work for you.

Common misunderstandings (and what to notice instead)

Misunderstanding: it’s a “rule”

People often repeat the saying as if it predicts what will happen. But it’s a proverb, not a forecast. It’s a way of describing a pattern after the fact.

Misunderstanding: it always has to be about the outdoors

It doesn’t. It’s used constantly in non-literal ways:

• “The meeting came in like a lion and went out like a lamb.”
• “The new manager came in like a lion, but things softened later.”
• “That debate started fierce and ended friendly.”

What to notice in your own life

If you want to “spot” this proverb in action, look for situations with a clear shift in tone:

• A loud beginning that settles down
• A tense start that turns cooperative
• A chaotic first week that becomes routine

When you notice that shift, you’ll start hearing the phrase differently. It’s less about a specific month and more about how people narrate change.

Why it still works in modern speech

Modern life is full of fast transitions—new apps, new jobs, new routines, sudden news cycles. The lion-and-lamb line survives because it’s a compact way to describe emotional whiplash. It also sounds friendly. It’s not harsh or blaming. It’s almost playful.

And unlike many old sayings, it doesn’t require special knowledge. You don’t need to know the original play, the history of almanacs, or anything about constellations. The images are enough.

The phrase “March comes in like a lion” endures because it gives people a simple script for a complicated experience: the way a stretch of time can start one way and end another. Whether it began in a line of English drama, spread through almanacs, or picked up extra meaning from the stars, it has lasted for the same reason most good sayings last—it turns change into a story you can say in one breath, and it makes that change feel a little more manageable.
