If you have ever heard Chicago’s classic song “25 or 6 to 4,” you may have wondered what the strange title means. Is it a secret code? Does it refer to a date, a math problem, or something deeper?
The answer is much simpler. “25 or 6 to 4” refers to a time of day. The phrase describes a moment when it is either 25 minutes before 4:00 or 26 minutes before 4:00. In other words, the song title points to a time around 3:35–3:34 a.m.
People search for the 25 or 6 to 4 meaning because the title sounds mysterious. The wording is unusual, and the song itself has a powerful, dreamlike feeling. Understanding the title helps listeners understand the song’s setting and the experience behind its lyrics.
In this guide, we explain the meaning, origin, history, common interpretations, and everyday ways people discuss this famous Chicago song.
25 or 6 to 4 Meaning – Quick Answer
The 25 or 6 to 4 meaning is a reference to the time shortly before 4:00 a.m.
- 25 to 4 = 3:35 a.m.
- 26 to 4 = 3:34 a.m.
The songwriter, Robert Lamm, used the title to describe a late-night or early-morning moment while writing.
The title is therefore not a mathematical equation. It is a poetic way of saying that it was somewhere around 3:34 or 3:35 in the morning.
Simple example
If someone says:
“It was 25 to 4.”
They mean:
“It was 3:35.”
The unusual part of Chicago’s title is the phrase “25 or 6 to 4.” It suggests uncertainty between two nearby times.
The Origin of 25 or 6 to 4
“25 or 6 to 4” was written by Robert Lamm, a founding member and keyboardist of the American rock band Chicago.
The song appeared on Chicago’s second album, originally titled Chicago, which was released in 1970. It became one of the band’s best-known songs.
Lamm has explained that the title came from the time when he was writing the song. He was working late at night and looking out at the Chicago skyline. He was unsure whether it was 25 or 26 minutes before 4:00.
That gives us the basic calculation:
4:00 − 25 minutes = 3:35
4:00 − 26 minutes = 3:34
The title captures a very specific late-night feeling. Instead of simply calling the song “3:35,” Lamm used the more unusual phrase “25 or 6 to 4.”
Why does it say “or”?
The word “or” is important.
It suggests that the exact time was uncertain. The writer knew it was close to 4:00 but was not sure whether it was 25 or 26 minutes away.
This uncertainty also adds to the song’s mysterious mood.
Is 25 or 6 to 4 a Secret Code?
No. There is no need to treat the title as a secret code.
Some listeners have suggested different meanings over the years, including references to drugs, mystical experiences, or hidden messages. These theories became popular because the song has an intense psychedelic-rock sound.
However, the commonly reported explanation from Robert Lamm is much more straightforward: the title refers to the time around 3:34–3:35 a.m.
The mysterious wording is part of what makes the song memorable.
Why Is It Written “25 or 6 to 4”?
The phrase is unusual because most people would simply say:
“It was 3:35.”
Instead, the song uses:
“25 or 6 to 4.”
This gives the title a more poetic and musical quality.
It also creates a sense of being awake during the strange hours of the night. At 3:34 or 3:35 a.m., most people are asleep. A person sitting awake and writing music at that hour may experience the world differently.
The title therefore works on two levels:
- Literal meaning: A time close to 4:00 a.m.
- Atmospheric meaning: A late-night moment of creativity, uncertainty, and reflection.
British English vs American English Spelling

Common Mistakes with 25 or 6 to 4
Because the title is unusual, people often misunderstand it.
Mistake 1: Treating it as a math problem
Some people think:
25 or 6 to 4
is a mathematical expression.
Correction: It refers to time.
Mistake 2: Thinking it means 25:64
The title does not represent a clock time such as 25:64.
Correction: It means approximately 25 or 26 minutes before 4:00.
Mistake 3: Assuming it is a date
The numbers may look like a date.
Correction: The title refers to a time of day, not a calendar date.
Mistake 4: Assuming “6 to 4” means 6:04
In normal time language, “six to four” means six minutes before four.
So:
6 to 4 = 3:54
The full title says 25 or 6 to 4, meaning approximately 3:35 or 3:54 depending on how the phrase is interpreted literally.
However, the well-known explanation of the title connects it to being 25 or 26 minutes before 4:00, or roughly 3:34–3:35 a.m.
Mistake 5: Assuming the title has one universally agreed symbolic meaning
The song has inspired many interpretations.
Correction: The strongest explanation comes from Robert Lamm’s account of the title’s origin. Other interpretations are best treated as theories.
