name: managing-date-selection description: Implements the "Restart Logic" for date range selection in the Tourly search widget. Use when building or modifying the date picker, handling check-in/check-out dates, or implementing calendar interaction algorithms.

Smart Date Range Selection Logic (Tourly)

When to use this skill

• Implementing the date range selection in the search bar or booking forms.
• Modifying react-day-picker or Shadcn Calendar behavior to match Tourly's custom "Restart Logic".
• Handling edge cases where users select an earlier date than the current start date.

Workflow

• Initialize state for startDate, endDate, and isCalendarOpen.
• Implement the handleDateSelect algorithm following the Scenarios below.
• Apply visual styles to the input field and calendar cells based on the selection state.
• Ensure the popover only closes on a valid range completion.

The Smart Range Algorithm

Scenario A: Starting Fresh / Resetting

• Condition: No dates selected OR both dates selected and a new date is clicked.
• Action: Set startDate to selected, endDate to null. Keep popover OPEN.

Scenario B: Valid Range Completion

• Condition: startDate exists, endDate is null, and selectedDate > startDate.
• Action: Set endDate to selected. CLOSE popover.

Scenario C: Backwards Selection (Restart Logic)

• Condition: startDate exists, endDate is null, and selectedDate < startDate.
• Action: Set startDate to selected, endDate to null. Keep popover OPEN.
• Note: Do NOT swap dates. Treat this as a correction of the start date.

Visual Requirements

• Input Text: Use low-opacity/gray text (e.g., text-muted-foreground) to match placeholder style.
• Calendar Header: Must display "Select Dates".
• Highlighting:
  • Ends: Solid primary color circles.
  • In-between: Light primary background (e.g., bg-primary/20) for the range.

Instructions

• Closing Rule: The popover MUST NOT close until Scenario B is met. Automatic closing on the first click is a failure.
• Library Integration: When using react-day-picker, intercept the onSelect or onDayClick events to apply this custom logic manualy rather than using the default range mode.
