The Calendar Converter MCP server provides a powerful engine for bidirectional date conversions across over 15 distinct solar, lunar, and lunisolar calendar systems. Using Unix timestamps as a universal pivot, it allows AI agents to bridge the gap between different cultural and historical timekeeping methods.

Key capabilities include:

  • Multi-Calendar Conversion: Seamlessly convert dates between Gregorian, Julian, Islamic (Hijri), Hebrew, Persian (Solar Hijri), Buddhist, Chinese, Ethiopian, Coptic, Indian National, Japanese Era, Thai Solar, and Unix timestamps.
  • Temporal Expansion: Use the expand_unix tool to take a single Unix timestamp and instantly see its equivalent date and era/zodiac details across multiple requested calendars.
  • Cultural Metadata Retrieval: Access seasonal or era-based metadata using get_calendar_context. For example, find the Chinese Zodiac animal for a specific year or identify the Imperial Era in the Japanese calendar.
  • Precise Timestamping: Use convert_to_unix to find the exact Unix epoch for any valid date in supported systems, including hours, minutes, and seconds.

This server is ideal for applications requiring historical accuracy, cultural awareness, or cross-calendar synchronization.
