This paper details a limited-time promotional campaign initiated by Claude, active from March 13, 2026, through March 27, 2026, concluding at 11:59 PM PT. The primary objective of this promotion is to enhance user engagement by providing a conditional doubling of usage capacity for eligible users.

The core methodology involves a temporal scaling of user resource allocation. Specifically, for all eligible user accounts, their standard usage limits are multiplied by a factor of two ($R_{promo} = 2 \times R_{standard}$) during designated "off-peak" hours. These off-peak hours are precisely defined as any time outside the 8:00 AM ET to 2:00 PM ET window, which equivalently corresponds to 5:00 AM PT to 11:00 AM PT. During the peak hours (8:00 AM ET-2:00 PM ET / 5:00 AM PT-11:00 AM PT), usage limits revert to their standard levels ($R_{promo} = R_{standard}$). This dynamic limit adjustment applies to the "five-hour usage" capacity, implying an increased throughput or volume allowance within each five-hour period that falls entirely within the off-peak window.

Eligibility for this promotional benefit is automatically conferred upon users subscribed to Free, Pro, Max, and Team plans. Enterprise plans are explicitly excluded from participation. The boosted usage is applied seamlessly, requiring no manual action or opt-in from the user. Furthermore, any additional usage accrued during this promotion, under the doubled limits, is explicitly stated not to count towards a user's standard weekly usage limits, effectively offering a bonus quota.

The scope of this usage increase spans across multiple Claude-powered interfaces and applications, including the core Claude platform (web, desktop, and mobile versions), Cowork Claude, Claude Code, Claude for Excel, and Claude for PowerPoint. Upon the conclusion of the promotion on March 27, 2026, all usage limits will automatically revert to their pre-promotional standard levels without any modifications to the user's plan or billing structure. The offer has no cash value, is non-transferable, and cannot be combined with other ongoing promotions.
