• Added a powerful, calendar-aware date engine for complex arithmetic and natural language queries (e.g., today + 3 weeks).
• Added new interval operators: to, between (exclusive), and through (inclusive).
• Added support for timezone conversions (e.g., now in "Japan").
• Added explicit date and time constructors: date(), datetime(), datetimeZ(), and parseDate().
• Added support for forcing interval results into specific units (e.g., today through tomorrow in hours).
