## Interpreting natural language

Map user requests to JSON fields:

| User says | JSON |
|---|---|
| "tomorrow at 2pm" | `offset_days: 1, hour: 14` |
| "in 3 days" | `offset_days: 3` |
| "next Monday at 10am" | Calculate offset_days from today to next Monday, `hour: 10` |
| "February 25 at 3:30pm" | `iso_date: "2026-02-25", hour: 15, minute: 30` |
| "every weekday at 9am" | `hour: 9, recurrence: "FREQ=WEEKLY;BYDAY=MO,TU,WE,TH,FR"` |
| "remind me 1 hour before" | `alarm_minutes: 60` |
| "all day event on March 1" | `iso_date: "2026-03-01", all_day: true` |

For "next Monday", "next Friday" etc: compute the day offset using the current date. Use `date` command if needed:

## Example prompts
