Forecast or backtrack quickly

  • Answer scheduling questions such as "What date falls exactly 120 days after March 4, 2026 and what weekday is it?".
  • Backtrack reminders like "Which day is 6 weeks before September 1, 2025 so I can start procurement?".
  • Handle timestamp-level needs—"If we add 18 hours and 45 minutes to April 8 at 09:15 UTC, what instant do we hit?"—with UTC summaries and ISO strings.
