Anthropic’s stated peak window

5 AM–11 AM

Weekdays, 5–11 AM Pacific, shown in Pacific Time. In March 2026 Anthropic said 5-hour limits drain faster during these hours; on May 6, 2026 that reduction was removed for Claude Code on Pro and Max, but it remains the busiest part of the day.

Planning your day

The global weekday peak is 5 AM–11 AM in Pacific Time. In Pacific Time that window only brushes the edge of your working day. It is when North American mornings overlap with the European afternoon, so slow responses and overloaded errors are most likely then.

  • Long agent runs (refactors, migrations, test generation): start them before 5 AM or after 11 AM.
  • During the peak, favour short loops — reviews, small edits, questions about code — where a little latency hurts less.
  • Weekends are noticeably calmer than weekdays in every time zone.
  • If Claude is slow anyway, check the current load and the official status page.
