What Time Is “8:10 Before”? 5ch Can’t Agree — and Asks: “Why Won’t You Just Say 7:50?”

From our other sites

The story

On 5ch’s “Nandemo Jikkyo G” (general live-chat) board, a debate broke out over what the Japanese phrase “8-ji juppun mae” (lit. “8:10 before”) actually means. One camp reads it as shortly before 8:10 (around 8:05), while the other reads it as further back than that — i.e., ten minutes before 8:00 (around 7:50). The discussion expanded into whether the split comes down to generational differences in interpretation. Some argued the ambiguous phrasing itself is the problem, while others said it would be simpler to just say “7:50” outright.

Japanese is the problem for having so many ways to say the same thing.
Just say "7:50" or "ten minutes to 8" like a normal person.
7AnonymousOct 7, 2026 19:29
You can tell from the tone of voice.
Writing out a confusing phrase like that in text is just crazy ("gai," 5ch slang for "nuts").
10AnonymousOct 7, 2026 19:29
Well, you wouldn't bother specifying "10 minutes" anyway.
It'd just be "come before 8," right?
11AnonymousOct 7, 2026 19:30
But if someone says "please come before 8:30," nobody's showing up at 7:30 — so isn't there really just one natural reading?
12AnonymousOct 7, 2026 19:30
A sane person avoids phrasing that can be taken two ways as much as possible.
Just saying "7:50" or "8:09" straight up is the smart move.

Re: #12
This exactly.
The correct answer is that the Japanese in the question itself is weird.
13AnonymousOct 7, 2026 19:30
We already settled this: if an instruction can be read multiple ways, the one giving the instruction is incompetent.
14AnonymousOct 7, 2026 19:30
Bet the second you say "8:15 before," the number of people totally lost spikes.
15AnonymousOct 7, 2026 19:30
Why won't you just say 7:50?
16AnonymousOct 7, 2026 19:30
If you're ever unsure, just show up at 7:50 — that way nothing goes wrong either way.
17AnonymousOct 7, 2026 19:31
Why is there such a generational gap in how people read this?
Are schools even teaching it differently now?
18AnonymousOct 7, 2026 19:32
I don't think that's the point being made — isn't this more about pointing out a generational difference in nuance?
19AnonymousOct 7, 2026 19:33
I'm 36 but I'm apparently on the younger side here — "8:10 before" isn't even a concept I have.
20AnonymousOct 7, 2026 19:33
Kind of like the classic "Your father isn't dead, is he?" trick question (a famous example of built-in ambiguity in Japanese phrasing).
21AnonymousOct 7, 2026 19:33
This can seriously be read either way, no joke.
22AnonymousOct 7, 2026 19:34
Gen Z really is dumb as hell after all, huh.
23AnonymousOct 7, 2026 19:34
Is there ever even an occasion to say "before 8:10" specifically?
24AnonymousOct 7, 2026 19:34
People talk out loud less these days, so they're losing the ability to catch meaning from intonation.
25AnonymousOct 7, 2026 19:34
They just don't have the "let's get there early" mindset to begin with. To them, cutting it right down to the wire is the default.
38AnonymousOct 7, 2026 19:39
If someone says "before 8," you'd picture around 7:59, right?
So wouldn't "before 8:10" logically mean around 8:09?
44AnonymousOct 7, 2026 19:40
Re: #38
It's "before 8 (the nice round number)" —
so obviously it means "10 minutes before 8 (the nice round number)."
48AnonymousOct 7, 2026 19:42
So how would the 7:50 camp phrase "gather before 8:10," then?

Not trying to be snarky, genuinely asking.
53AnonymousOct 7, 2026 19:44
Re: #48
"Gather by 8:10."
59AnonymousOct 7, 2026 19:48
Re: #48
What's "before 8:10" even supposed to mean.
66AnonymousOct 7, 2026 19:50
Wait, now I'm not sure either.
If someone says "8:30 before," I'd assume they mean around 8:25.
74AnonymousOct 7, 2026 19:54
Re: #66
That's because it's a clean round number —
the ":30" actually gets counted.
86AnonymousOct 7, 2026 20:04
"Before 8" I get, but I've never seen anyone call 7:50 "before 8:10."
94AnonymousOct 7, 2026 20:07
Re: #86
Likewise, I've never seen anyone say "before the time 8:10" either.
91AnonymousOct 7, 2026 20:07
What even starts at 8:10 anyway?
Who sets a meeting time like that?
98AnonymousOct 7, 2026 20:12
Re: #91
I mean, train schedules probably have times like that.
99AnonymousOct 7, 2026 20:13
Is this some kind of riddle?
Is it "8:10 — before that"?
Or "8 o'clock, 10 minutes before"?
103AnonymousOct 7, 2026 20:17
Re: #99
Nah, unless you've lost your mind, it means before 8.
100AnonymousOct 7, 2026 20:14
Re: #98
In that case you'd just say "meet at 8," wouldn't you.
102AnonymousOct 7, 2026 20:15
Re: #100
There's stuff like a train "departing at :17," though.

Background and Key Points of the Debate

The phrase “X o’clock, Y minutes before” is grammatically ambiguous in Japanese: it can be read as pointing to just before the reference point “X o’clock” itself, or as pointing to just before the specific time “X:Y.” The clash in the thread stemmed not only from this structural ambiguity but also from a gap between people who have traditionally judged meaning from intonation and context, and those receiving it as plain text. The claim that “whoever gives an instruction that can be read multiple ways is at fault” and the counterargument that “intonation usually makes it clear” both have their own logic, and the thread never reached a consensus. What’s easy to miss here is that this isn’t simply a generational contest of right versus wrong — it’s a case where an expression that has always relied on the listener’s interpretation only became visible as a problem now that people communicate out loud less often.
