Anthropic is running a temporary promotion through March 27, 2026, that doubles usage limits for Claude users during off-peak hours — defined as all hours outside of 8AM to 2PM Eastern Time. The promotion applies automatically to Free, Pro, Max, and Team plan subscribers, with Enterprise customers excluded. The bonus capacity does not count toward users' existing weekly usage caps, making it additive compute rather than a reallocation of existing allowances. No action is required; the doubled limits activate automatically during eligible windows.
To help Claude's global user base navigate the Eastern Time-based <a href="/news/2026-03-14-anthropic-doubles-claude-usage-limits-off-peak">promotion</a>, a third-party developer at AIgnited built an interactive web calculator at site.aignited.id/claude-2x.html. The tool translates Anthropic's raw ET-based peak window into each user's local timezone, featuring a 24-hour timeline visualization, live world-clock status for 19 major cities updated every 10 seconds, and practical scheduling advice. The site is self-described as unaffiliated with Anthropic and operates without tracking or cookies, sourcing its data from Anthropic's official support announcement.
The geographic split is uneven. Users in Asia and Oceania benefit most: the 8AM–2PM ET peak window corresponds to their late-night hours, meaning their entire standard workday falls in the 2× window. Jakarta users, for example, get up to 18 hours of double capacity during working hours. European users see peak hours roughly align with 1–7PM CET, enabling double usage during mornings and evenings. US-based users need to actively shift habits, capturing the benefit either before 8AM ET or after 2PM ET.
Anthropic has not publicly explained why Enterprise plans are excluded or offered detail on the infrastructure rationale behind the specific 8AM–2PM ET window. The promotion ends at 11:59PM PT on March 27, 2026 (6:59AM UTC on March 28).
