Parse Natural Language Dates with GPT-4o for Smart Scheduling

This n8n workflow leverages OpenAI GPT-4o to parse complex natural language date and time expressions into structured datetime data. It handles inputs like '2 weeks after project launch' or 'end of Q3' with high accuracy, including confidence scoring, multi-language support (English, Spanish, French, German, Italian, Portuguese), and auto-detection. The workflow processes text via webhook, form, email, or chat inputs.

Key features include 50+ custom rule patterns, ambiguity detection with suggestions, holiday awareness, working hours validation, business day adjustments, and IANA timezone normalization. It outputs structured datetime objects (start/end times), metadata for decision-making, and alternative interpretations, enabling seamless integration with calendars, CRMs, or other automations.

Benefits: Achieves sub-millisecond responses with caching, improves via AI learning from corrections, and provides enterprise-grade reliability. Use cases span HR for performance review scheduling, operations for project deadlines, sales for follow-ups, and any scenario needing smart date parsing to automate workflows efficiently.
