The phrase “cuántos días” translates to “how many days” in English.

• [cuántos días](javascript:void(0)) — How many days
• Usage notes:
  • Ask about duration: ¿Cuántos días te quedas? -> How many days are you staying?
  • Used in general questions about counting days or time spans.

If you need a specific answer (e.g., "how many days until a date" or "how many days between two dates"), tell me the dates or the event you’re counting, and I’ll compute it.
