Every known z.ai bonus window, multiplier and limited-time discount — computed live in your browser with ticking countdowns, timezone-aware timelines and a Prometheus-compatible metrics endpoint. No stale screenshots, no guessing when to fire the heavy agent runs.
Status badges flip automatically as windows open and close. Countdowns tick every second; schedules are evaluated against Asia/Singapore time exactly as the official notices define them — and an AI bot re-verifies them against docs.z.ai every hour.

z.ai
Peak hours surcharge
inactive
Time-variable rates apply during peak hours. Code off-peak and the same credits last twice as long.
The same 24 hours shown twice: once in schedule time (SGT), once in your local clock. Line up the bright segments and you never accidentally pay peak rates again.

Bars start at midnight in each timezone. The peak surcharge only runs Mon–Fri; the flash campaign paints the whole night. Wherever you are, the night bar is when the stack is deepest.

China ops calendar
z.ai is built in Beijing — during China's public holidays (Golden Week, Spring Festival and friends) support replies, pricing updates and non-critical releases slow down across China-based companies. Plan heavy work and deadline-sensitive runs around these windows; the API itself stays up.
China public holidaysAsia/Shanghai · UTC+8 · no DST
z.ai is built in Beijing, and its teams observe China's public holidays — during Golden Week, Spring Festival and the shorter festivals, support replies and non-critical releases slow down across China-based companies while the API itself stays on-call.
2026 official schedule (State Council notice)
New Year's Day · 元旦Three-day long weekend; support usually reduced on Jan 1 only.
Spring Festival · 春节The longest shutdown of the year — most teams away, expect multi-day support delays and a release freeze.
Qingming Festival · 清明节
Labour Day · 劳动节Five-day travel peak; skeleton crews on support, releases paused.
Dragon Boat Festival · 端午节
Mid-Autumn Festival · 中秋节
National Day Golden Week · 国庆节The other full-week shutdown: support and non-critical releases wind down; API infra stays on-call.
China has 13 statutory holiday days a year, extended into week-long breaks by swapping weekends — the swapped-in Saturday/Sundays are working days with normal operations. 2026 dates follow the official State Council notice; later years are the expected pattern until published (usually each November). API infrastructure stays on-call through every holiday — this affects support, pricing updates and release pace far more than uptime.

Credits-based plans for Claude Code, Cline, OpenCode, ZCode and more. Off-peak usage bills at 50% of the standard credit rate — the same window the radar tracks above.
Lite
Daily driving for solo developers — quick fixes, codebase Q&A, completion-heavy work.
Credits refresh dynamically: the 5-hour bucket resets 5 hours after consumption, the weekly bucket resets every 7 days. Credit usage = (input × input multiplier + cached input × cached multiplier + output × output multiplier) ÷ 10,000 — and everything billed off-peak costs half. Source: GLM Coding Plan overview ↗
