Deterministic temporal reasoning engine for AI agents. LLMs are surprisingly bad at dates, timezones, business days, holidays, and recurring schedules. Taghvim gives agents deterministic temporal primitives they can call instead of guessing.

Real public/bank/school holiday lookup for 206 countries via a rule-based calendar engine (moveable holidays like Easter computed astronomically, not guessed). Priced per call via x402/USDC on Base.
