A remote MCP server that provides ambient time awareness, enabling current time, timezone conversion, calendar math, and elapsed-time calculations via natural language, designed for Claude custom connectors.

Computes fixed divination and astronomy facts for any moment — Liu Ren charts, Qimen Dunjia layouts, symbolic stem-branch directions, and the real geometric position of the Big Dipper at a given latitude/longitude — alongside multiple named birth profiles. It also assembles day-by-day candidate windows for a chosen purpose across a 1–7 day range or a full calendar year, accumulating model-filled verdicts into an offline, month-switchable HTML calendar with a local browser preview.
