About

Claude's March 2026 promotion doubles your usage limits outside peak hours (8 AM – 2 PM ET, weekdays). This extension makes sure you never miss the transition.
 
FEATURES:
• Live badge countdown on the toolbar icon showing time until the next peak/off-peak switch
• Color-coded badge: red during peak hours, green during off-peak
• Desktop notifications when peak hours start and end
• Auto-detects your timezone and shows your local peak hour equivalent
• Works for any timezone worldwide — no configuration needed
• Auto-disables after the promotion ends (March 27, 2026)
 
WHAT ARE PEAK HOURS?
During Anthropic's March 2026 promotion, Claude usage limits are doubled outside 8 AM – 2 PM ET on weekdays. This extension tracks that window and alerts you at each transition so you can plan your Claude usage accordingly.
 
PLANS COVERED:
Free, Pro, Max, and Team plans. Enterprise plans are not included in the promotion.
 
PRIVACY:
This extension collects zero user data. It stores a single local value to track the current peak/off-peak state. No network requests are made.
