"Rime" matching MCP servers:

Provides accurate time zone conversions, DST-safe scheduling, holidays for 200+ countries, business day calculations, and cross-zone meeting slot suggestions.

True solar time (longitude correction + equation of time), exact moments of the 24 Chinese solar terms for any year, and China 1986–1991 DST handling for BaZi birth-time conversion.

Gives time-blind LLMs and agent frameworks a real clock: current time and timezone, elapsed task duration, countdowns to deadlines, timezone conversion, session heartbeats, cron-style due checks, and session-level timers. This lets locally hosted or self-built models stop hallucinating the time and actually perceive how long a task or conversation has been running.

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.

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.

Enables AI agents to query Iran's official calendar from Time.ir, convert dates across Jalali, Gregorian, and Hijri calendars, check holidays and occasions, and retrieve prayer times for Iranian cities.

Enables managing a Google calendar as a set of non-overlapping events representing one person's time.

Enables reading, creating, updating, and deleting Apple Reminders directly on macOS via the EventKit framework.

Read your Pyunto Time Management schedule and log time from an AI assistant. E2EE project planning.

Calendar and task management with kernel-level scraping for robust parsing, and integrates with DocMost wiki as source of truth.
