When is my reset?

Works for Claude Code and Codex limit messages.

Read and calculated in this browser tab. The text you paste and the calendar file never leave your computer.

How it reads the reset text

Paste the line from the limit message, for example resets 3:45pm or resets Mon 12:00am. The calculator works out the next moment that matches, converts it to your time zone, starts a countdown and can save it to your calendar. If it can’t be sure, it says “couldn’t read that” instead of guessing.

It understands the shapes these messages take:

A time: resets 3:45pm, 11:59 PM, 15:45, noon. A bare time means its next occurrence: today if it’s still ahead, otherwise tomorrow.
A weekday and time: resets Mon 12:00am. That means the next Monday at midnight, or today if it is Monday and the time is still ahead. Weekly-limit messages look like this.
A date: Oct 12, 3pm, 12 Oct 2026 08:00 or 2026-10-20 08:00.
A duration: try again in 2 hours 15 minutes or in 2h 15m, counted from now.
A time zone, when one is shown: (Europe/Paris), (UTC) or (GMT+2). Without one, your browser’s time zone is used.

Some inputs are refused on purpose. 3:45 with no am or pm could be morning or afternoon, so you’re asked to add it (a leading zero, as in 03:45, or an hour over 12 reads as 24-hour time). Abbreviations such as PST or CET are refused because the same letters mean different offsets in different places. Use the city-style name instead, such as America/Los_Angeles.

The conversion uses your browser’s built-in time zone database, so daylight-saving changes between now and the reset are handled. The countdown updates every second. The calendar button builds a standard .ics file with one 15-minute event and an alert at the reset time.

How Claude Code limits reset

Anthropic’s help center says the Claude Code session limit resets every five hours, and the weekly limit resets once a week at a fixed time assigned to your account. For Max, that weekly day and time stay the same no matter when you started using Claude or when your subscription began. Max plans also have a separate weekly limit for Fable, so check which limit a message names.

You don’t need to work the time out yourself. Claude Code prints it in the limit message, /usage shows it at any time, and claude.ai lists your next reset under Settings → Usage. A session-limit message shows a time; a weekly-limit message adds the day. Usage counts against both allowances at once, so after a heavy week only the weekly reset gets you going again.

How Codex limits reset

Codex is included with ChatGPT plans. Depending on the plan, limits apply over a five-hour window and a weekly window, and you need room in both. OpenAI says a new five-hour window starts with your first message after the previous window ends. That means the time follows your activity, not the clock. The weekly period follows your previous weekly reset date, and using a banked or purchased reset can move it. ChatGPT Pro currently has no five-hour limit.

The Codex usage dashboard at chatgpt.com/codex/settings/usage shows your current reset times, and /status shows remaining limits in an active CLI session. Paste whatever time Codex shows you into the calculator. More in Codex usage limits, explained.

What this tool can’t know

Whether your allowance is really back. The calculator only knows the time you gave it. It can’t see your account, so a countdown at zero isn’t proof you have room. Check /usage or the Codex dashboard.
When you saw the message. Relative times such as “in 2 hours” are counted from the moment you paste them. If the message is an hour old, subtract that hour or pick the time yourself.
The time zone of a message without one. It assumes your own time zone, which is right when Claude Code or Codex runs on the computer you’re using. On a remote server in another zone, include the zone.
Your limits themselves. Neither Anthropic nor OpenAI publishes allowances as exact numbers, and nothing here estimates what’s left.

Tips

Copy the whole limit line. Extra words are fine, and the calculator looks for the time and any zone in brackets.
Add the .ics file to your calendar before you step away. The event has an alert at the reset time.
For Claude Code, consider /rate-limit-options. In an interactive session signed in with a claude.ai subscription (v2.1.234 or later), Claude Code can wait and resume the interrupted task shortly after the reset.
Want the reset in your terminal all the time? Our status line generator builds a script that shows a live countdown.

Quotchi keeps your Claude Code and Codex reset times in the Mac menu bar. It waits for a fresh reading before it shows room again, and “Notify me when it’s back” tells you when it does. It’s Free and needs no account.

Embed this calculator

The calculator is a self-contained module. On a quotchi.com page, add the stylesheet, an empty block and the script:

<link rel="stylesheet" href="/tools/tools.css">
<div id="reset-calculator"></div>
<script type="module" src="/tools/reset-calculator.js"></script>

It mounts itself into #reset-calculator. To mount it elsewhere, import mountResetCalculator(element) from the same file. parseResetText and buildICS are exported too.

FAQ

Which time zone does the calculator use?

If the reset text includes a time zone in brackets, such as (Europe/Paris), it reads the time in that zone. Otherwise it uses your browser’s time zone. The result is always shown in your local time.

Why does it say “couldn’t read that”?

It only answers when it’s sure. A time without am or pm, an abbreviation like PST that means different things in different places, or text without a time is refused instead of guessed.

How often does the Claude Code limit reset?

The session limit resets every five hours. The weekly limit resets once a week, at a fixed time assigned to your account.

When does the Codex five-hour window start?

OpenAI says a new five-hour window starts when you send your first message after the previous window ends, so it follows your activity rather than the clock.

Is my limit definitely back when the countdown ends?

Not necessarily. The calculator only knows the time you gave it. Check /usage in Claude Code or the Codex usage dashboard before you start a long task.

What does the calendar file contain?

One 15-minute event at the reset time, with an alert, built in your browser. Nothing is uploaded; open the .ics file to add it to Apple Calendar, Google Calendar or Outlook.
