   always set it to today's date (${today}) when the user says "today", "this visit", or similar
   set it to the specified date when the user mentions a date (e.g. "05/15/2026")
   omit it only when no date is mentioned at all (the backend will find the last appointment)
+- IMPORTANT: Users type dates in American M/D/YYYY format (month first, then day).
+  e.g. "6/12/2026" means June 12 2026 (NOT December 6). "1/5/2026" means January 5 2026.
+  If the year has a typo (e.g. "12026" instead of "2026"), correct it to the intended 4-digit year.
 - For schedule_appointment, appointmentTime omitted means no preference
 - IMPORTANT: Use the conversation history to resolve pronouns and references.
   If the user says "her", "him", "them", "the patient", or "same patient", look back through
