What Does 4/20 Mean?
Before we talk about the history, it helps to know what 4/20 means today.
For many people, 4/20 means two things:
- A time — 4:20 on the clock
- A date — April 20
It is now linked to weed culture around the world. On April 20, some people gather for events, music, marches, or community celebrations. Some people simply use the day to talk about weed history, freedom, and changing laws.
Still, the biggest question remains: How did 4/20 start?
The Real Story of How 4/20 Started
The most accepted story about the history of 4/20 begins in the early 1970s in San Rafael, California.
A group of high school students used to meet after school. They became known as the Waldos because they liked hanging out near a wall. One day, they heard a story about a hidden weed patch that someone had planted but no longer cared for. The group decided they would try to find it.
They planned to meet after school at 4:20 p.m. They chose that time because school activities were over by then, and it was easy for everyone to meet.
At first, 4:20 was just their private code. It meant, “Let’s meet at 4:20 and go look for the weed patch.”
That is the heart of how 4/20 started. It began as a small inside joke and meeting time among friends.
Why 4:20 Became a Code
The Waldos started saying “4:20” to each other as a secret code. Instead of explaining everything out loud, they could just say the number.
Over time, the meaning changed a little. At first, it meant meeting up to search for the hidden plants. Later, it became a general code word connected to weed.
This is an important part of the history of 4/20 and how it started. It was never first meant to be a national holiday. It was just a simple code used by a few teenagers.
That simple code was catchy, easy to say, and easy to remember. Those three things helped it spread.
Did They Ever Find the Hidden Weed Patch?
The funny part of the story is that the group never really found the famous hidden patch.
But even though they did not find the plants, they created something much bigger without knowing it. Their little phrase lived on. It became one of the most famous numbers in weed culture.
That is part of what makes the history of 4/20 so fun. The search may not have worked, but the code lasted for decades.
How 4/20 Spread Beyond One Friend Group
A lot of people wonder how a code from a small group of students became something known all over the world.
One reason is that the Waldos had connections to people around the music world in California. The phrase slowly moved from friend groups to wider social circles. Over time, more people started hearing “4:20” and using it.
As the years passed, the term spread more and more. It moved through conversations, events, and culture. Eventually, newspapers, magazines, and the internet helped make it even bigger.
This is a key part of how 4/20 became popular. It grew little by little before it became mainstream.
The Role of Weed Culture in the Growth of 4/20
The rise of 4/20 is closely tied to weed culture itself.
For a long time, weed was discussed in secret by many people. Slang, code words, and symbols were often part of that world. So a number like 4:20 fit right in. It gave people a way to refer to weed without saying it directly.
That helped 4/20 grow.
Later, as weed laws slowly began to change in some places, 4/20 became more open and public. What started as a hidden code became something used in ads, events, headlines, and everyday talk.
So when people ask about the history of 4/20 and how it started, they are also asking about how weed culture changed over time.
Myths About 4/20
There are many myths about how 4/20 started. Some sound exciting, but they are not true.
Here are a few popular myths:
Myth 1: 4/20 Is a Police Code
Many people once thought 420 was a police code for weed. But that is not where the term came from.
Different police departments use different number systems, and the famous 4/20 meaning did not start with law enforcement.
Myth 2: 4/20 Is About the Number of Chemicals in Weed
Some people said 420 came from the number of chemicals in the weed plant. That is also not true.
The plant contains many compounds, but that is not the source of the term.
Myth 3: 4/20 Started as a National Holiday
It did not begin that way. It started as a meeting time for a small group of teens in California.
These myths show why people still search for the real history of 4/20. The truth is actually simpler than many of the stories people made up later.
When Did April 20 Become a Big Deal?
At first, 4:20 was about the time of day. Later, people connected it to the date April 20, written as 4/20.
That date slowly became special in weed culture. Over time, it turned into a day when people gathered for rallies, concerts, public events, and celebrations.
As weed culture became more visible, April 20 became a bigger deal each year. What was once a hidden code became a date known by millions.
