Calendar entries come from public release notes. Some changes roll out gradually and may depend on your plan. Blank days mean no entry is recorded in these sources.
Reset markers show dates reported by Codex Resets, a community tracker. They do not show your personal quota or predict future resets. Dates use UTC for resets and the date printed in the release notes for updates.
