Claude peak hours in your time zone

Everything this page shows comes from Anthropic’s own posts and pages, with their dates:

1. March 26, 2026: Anthropic announced that the 5-hour session limits of Free, Pro and Max subscriptions move faster during weekday peak hours, 05:00–11:00 Pacific Time. Weekly limits were unchanged; about 7 % of users would hit session limits they would not have hit before, particularly on Pro.
2. May 6, 2026: the peak-hours reduction was removed for Claude Code on Pro and Max, and Claude Code’s five-hour limits doubled for Pro, Max, Team and seat-based Enterprise.
3. September 22, 2026: with Claude Opus 5.5, Anthropic raised the five-hour limits of Pro, Max and Team. The announcement doesn’t mention peak hours.
4. September 24, 2026: the help center, plan and pricing pages don’t mention peak hours. No end has been announced for chats, and no current schedule is published.
5. At any hour: no surge pricing. Subscriptions keep their price and usage credits are billed at standard API rates, whatever the time.

Only the 5-hour session limit of Free, Pro and Max was concerned: during the window, the same messages use more of it. Your weekly limit doesn’t change, nothing costs more, and since May 6, 2026 Claude Code on Pro and Max is out of it.

Anthropic suggested moving token-heavy background jobs off-peak. If the window still applies to your chats, a long session started outside it leaves more of your 5-hour limit for the work itself. In much of Asia and Oceania, the whole window falls in the evening or at night.

While the US is on daylight time, 05:00–11:00 in Los Angeles is 08:00–14:00 in New York, 13:00–19:00 in London, 14:00–20:00 in Paris or Berlin, 17:30–23:30 in India and 21:00–03:00 the next day in Tokyo. In the US winter it starts an hour later in zones without daylight saving (18:30 in India, 22:00 in Tokyo). The weekend is the Pacific one: late on a Friday in California is already Saturday in Asia, and still inside the window.

Daylight saving moves it too. In 2026 the US changes its clocks on March 8 and November 1, the UK and the EU on March 29 and October 25: between those dates the window starts an hour earlier on European clocks. The converter uses your device’s time-zone rules, so those weeks come out right.

Whether Anthropic applies a peak-hours adjustment at a given moment can’t be seen from outside: no page shows it, and no one outside Anthropic can measure it. This converter shows the last published window on your clock; it doesn’t read your account. Your session bar in Settings › Usage, or the UsageMeter extension, shows how fast your limit is really going down.
