When does my Claude limit reset?

Every Claude plan has a session limit on a rolling five-hour window. In practice, the window opens with the first message you send while no window is open, and your limit comes back about five hours later. Until then, everything you send in claude.ai, the desktop and mobile apps, Cowork and Claude Code counts against the same session.

Example: your first message goes out at 09:00, so your limit comes back around 14:00, whether you send three messages or three hundred. A message at 14:30 opens a new window, which ends around 19:30.

Anthropic does not say to the minute when a window starts, and some trackers count it from the top of the hour. The exact time is always in Claude: Settings › Usage shows the time remaining in your current session. That is why the calculator also accepts the time Claude shows, and the time left.

Paid plans add a weekly limit that applies across all models. It resets at a fixed time each week assigned to your account: it does not depend on when you start using Claude or when your subscription began.

The calculator cannot guess it, so it asks for it: Settings › Usage shows the day and time of your next weekly reset. Enter them under “Weekly reset” to get a countdown next to the session one.

Anthropic occasionally gives eligible plans a limit reset. Depending on the one shown, your five-hour session or your weekly limit goes back to full right away; you do not have to wait until you reach a limit to use it. It is in Settings › Usage on the web or in Claude Desktop (“Reset for free”), and on the message shown when you reach a limit, but not in the mobile app or in Claude Code. Once used it cannot be undone, and an unused reset expires on the date shown.

In March 2026 Anthropic said that 5-hour session limits move faster during weekday peak hours, 05:00–11:00 Pacific Time; weekly limits were unchanged. On 6 May 2026 that reduction was removed for Claude Code on Pro and Max. For chats, no end has been announced and no current schedule is published, so the tool shows that window as the last one published, converted to your time zone, not as a rule in force.

The calculator does not read your account: it applies the five-hour rule to the time you give it, in your browser. It does not see your weekly limit unless you enter it, the usage of your other devices, or a change Anthropic may make to these rules. The UsageMeter extension reads the limits Claude shows you and keeps them on screen, with the exact countdown.
