Multicultural Holidays Skill

What This Skill Does

This skill serves as the primary expert on multicultural heritage traditions, holidays, and events within the Caro product ecosystem. It ensures cultural sensitivity, inclusivity, and accuracy when working with holiday theme features.

Key Responsibilities:

• Maintain and extend the data-driven holiday configuration system
• Ensure cultural accuracy and sensitivity for all holiday representations
• Add new regional and cultural holidays with proper research
• Validate locale detection and default theme selection rules
• Guide PRD creation for new holiday features
• Operate the Holiday Debug Panel for testing

When to Use This Skill

Activate this skill when the user:

• Asks about adding a new holiday or cultural event
• Needs to modify existing holiday configurations
• Wants to understand the holiday theme system architecture
• Requests cultural sensitivity review for holiday implementations
• Needs help testing holiday themes with the debug panel
• Asks about locale-specific visibility rules
• Wants to plan new holiday features (PRD-first workflow)
• Needs to validate Hebrew calendar or other lunar calendar dates

Example Triggers:

• "Add Nowruz (Persian New Year) to the holiday themes"
• "Is the Diwali date range correct?"
• "How do I make a theme visible only in specific countries?"
• "Review the Hanukkah implementation for cultural accuracy"
• "Test what theme shows for users in Japan"
• "Plan the Eid theme feature"

Key Concepts

1. Visibility Types:

• global: Visible to all users during the active period
• locale-only: Visible only to users in specified locales

2. Default Theme Selection: Priority-based system using defaultFor rules:

• Priority 100: Locale match (country code like "US", "IL")
• Priority 90: Language match (language code like "he", "zh")
• Priority 50: Wildcard match (* for everyone)

3. Date Range Types:

• fixed: Same date every year (e.g., July 4th)
• calculated: Pre-calculated dates with lookup (e.g., Thanksgiving)
• hebrew: Uses Hebrew calendar lookup tables

4. Locale Detection: Timezone-based country detection using comprehensive mapping:

• America/New_York → US
• Asia/Jerusalem → IL
• Europe/Paris → FR
• etc.

Cultural Sensitivity Guidelines

DO:

• Research each holiday thoroughly before implementation
• Use authentic colors, symbols, and terminology
• Respect religious significance and sacred elements
• Include appropriate date ranges (including lead time)
• Consider timezone differences for global holidays
• Consult multiple sources for accuracy
• Test with the debug panel before deployment

DON'T:

• Mix religious symbols inappropriately
• Use stereotypical or caricatured representations
• Assume holidays are celebrated the same way everywhere
• Ignore regional variations of celebrations
• Force themes on users (opt-in by default)
• Use commercial/Westernized versions of sacred holidays

Sensitivity Matrix by Holiday Type

Religious Holidays (Highest Sensitivity):

• Hanukkah, Passover, Rosh Hashanah (Jewish)
• Eid al-Fitr, Eid al-Adha (Islamic)
• Diwali, Holi (Hindu)
• Christmas, Easter (Christian)

Approach: Respect sacred elements, avoid commercialization, use authentic symbols

National Holidays (Moderate Sensitivity):

• Independence days (July 4th, Bastille Day, etc.)
• Unity days (German Unity Day, etc.)

Approach: Use official colors/symbols, respect historical context

Cultural Celebrations (Lower Sensitivity):

• Lunar New Year (multicultural)
• Mid-Autumn Festival
• Carnival

Approach: Celebrate diversity, use festive elements appropriately

Adding a New Holiday

Step 1: Research Phase (PRD-First)

Create a PRD in docs/prds/holidays/ with:

• Holiday name and origin
• Cultural significance
• Date calculation method
• Color palette with meaning
• Symbol selection with justification
• Target locales
• Sensitivity considerations

Step 2: Implementation

A. Add to website/src/config/holidays.ts:

{
  id: 'nowruz',
  name: 'Nowruz',
  description: 'Persian New Year - celebration of spring equinox',
  emoji: '🌸',

  dateRange: {
    type: 'fixed',
    startMonth: 3,
    startDay: 20,
    endMonth: 3,
    endDay: 24,
  },
  leadTimeDays: 3,

  visibility: 'global',
  locales: ['IR', 'AF', 'TJ', 'KZ', 'AZ'],

  defaultFor: [
    { type: 'locale', values: ['IR', 'AF', 'TJ'], priority: 100 },
    { type: 'language', values: ['fa', 'ps'], priority: 90 },
  ],

  theme: {
    colors: {
      primary: '#00a651',    // Sabzeh green
      secondary: '#ffd700',  // Gold
      tertiary: '#ff6b35',   // Fire orange
    },
    effects: ['spring-blossoms'],
  },

  enabled: true,
}

B. Add CSS theme to Layout.astro:

.nowruz {
  --color-accent: #00a651;
  --color-accent-secondary: #ffd700;
  --color-bg-tertiary: #f0fff0;
}

.nowruz .cta-button {
  background: linear-gradient(135deg, #00a651 0%, #ffd700 100%) !important;
}

.nowruz .hero::before {
  content: '🌸';
  /* ... animation styles ... */
}

C. Add to debug panel preview buttons if needed

D. Add calendar lookup if using non-Gregorian calendar

Step 3: Testing

1. Open debug panel: Cmd+Shift+\
2. Set test date to holiday period
3. Set test locale to target country
4. Verify theme applies correctly
5. Check hero decorations render
6. Test on both light and dark modes

Step 4: Documentation

Update website/GLOBAL_HOLIDAY_THEMES_PLAN.md with:

• New holiday entry in regional section
• Implementation status
• Any special notes

Debug Panel Usage

Access Methods

• Hotkey: Cmd+Shift+\ (Mac) or Ctrl+Shift+\ (Windows/Linux)
• URL: Add ?holidayDebug=true to any page

Testing Workflow

1. Open debug panel (Cmd+Shift+\)
2. Click preset date OR enter custom date
3. Select locale from dropdown
4. Observe which theme is auto-selected
5. Use theme preview buttons to test CSS
6. Check Engine State for debugging

Remember

The goal of the holiday theme system is to:

• Celebrate diversity without appropriation
• Respect traditions from all cultures
• Create joy for users worldwide
• Remain opt-in to respect personal preferences
• Educate through authentic representation

Every theme should make users from that culture feel seen and respected, while introducing others to the beauty of diverse traditions.

This skill represents how Caro manages specialized features through dedicated expertise. The multicultural holidays system is a prime example of feature ownership through skills and sub-agents.
