"Claude AI usage limit reached|{unix_timestamp}"
Updated
"Claude AI usage limit reached|{unix_timestamp}" is a raw form of the Claude Code usage-limit error seen on 2025 builds such as v1.0.84: the text before the bar is the message, and the number after it is your reset time in Unix seconds. In issue #6119 the value 1755615600 is 2025-08-19 15:00 UTC. Underneath is an API 429 rate_limit_error. Run /usage to see the same time; it is not the account-wide reset this board tracks.

What does "Claude AI usage limit reached|{unix_timestamp}" mean?
On some 2025 builds, Claude Code printed the usage-limit error exactly as it came from the API: a message, a vertical bar, and a Unix timestamp. Issue #6119 (v1.0.84) has "Claude AI usage limit reached|1755615600" as its title, and 1755615600 seconds since 1970 is 2025-08-19 15:00 UTC.
The same issue shows the human-readable sentence in its body, "Claude usage limit reached. Your limit will reset at 5pm (Europe/Warsaw).", and the errors array carries an API 429 rate_limit_error: "This request would exceed your account's rate limit. Please try again later."
The current Error reference lists formatted messages instead: "You've hit your session limit · resets 3:45pm" and its weekly, Opus and Sonnet siblings. The window behind them is the same: a five-hour session limit and a weekly limit that resets at a fixed time assigned to your account.
Which window is full?
| Window | Resets | Where to check |
|---|---|---|
| Session limit (5-hour) | Every five hours; the exact time is the one in the message | /usage in Claude Code, or Settings > Usage on claude.ai |
| Weekly limit | At a fixed time each week that is assigned to your account | /usage in Claude Code, or Settings > Usage on claude.ai |
What to do when you see it
- Convert the number after the bar
It is seconds since 1970-01-01 UTC. Paste it into any epoch converter, or run date -r 1755615600 on macOS, to get the local reset time.
- Run /usage
It shows the session and weekly bars with their reset times, so you can confirm which window the timestamp refers to.
- Wait, then retry
Requests are blocked until the timestamp. On 2025 builds nothing resumes on its own; send the next prompt yourself.
- Update Claude Code
Current versions print the reset time in words and, since v2.1.234, can wait and continue automatically in an interactive subscription session.
- Report it if usage looks fine
If /usage shows room and the error keeps coming back, open an issue on anthropics/claude-code with the message and timestamp.
When does it reset?
Your own window: the timestamp is the exact reset moment for your window. Anthropic says the session limit resets every five hours and the weekly limit at a fixed time each week assigned to your account. Put the converted time on a countdown with the window tracker linked below.
Account-wide resets: separately, Anthropic sometimes announces a reset for everyone. Those are what this board records, each linked to its original post, and the row above shows the last one. They are announced, not scheduled, so this site does not promise one.

FAQ
What does the number after the bar mean?
It is a Unix timestamp: seconds since 1970-01-01 00:00 UTC. In issue #6119 the value 1755615600 converts to 2025-08-19 15:00 UTC, which is the moment that account's window refreshed. Convert it to your local time to know how long to wait.
What error is behind this message?
An API 429 rate_limit_error. Issue #6119's errors array shows "This request would exceed your account's rate limit. Please try again later.", and the Claude Platform error reference lists 429 rate_limit_error as the code for hitting a rate limit.
Is this the five-hour window or the weekly window?
The raw message does not say. Compare the timestamp with now: within five hours points to the session limit, days away points to the weekly limit. /usage shows both bars and their reset times directly.
Why do current versions not show this?
The Error reference now documents formatted messages such as "You've hit your session limit · resets 3:45pm". The bar-and-timestamp form appears in 2025 reports on builds like v1.0.84.
