Verta Laravel Package

Product Decisions This Supports

• Market Expansion: Enables seamless support for Persian-speaking regions (Iran, Afghanistan, Tajikistan) by natively handling the Jalali calendar, reducing localization barriers and improving user trust. Critical for apps targeting these markets where Gregorian dates are less intuitive.
• Compliance & Legal Requirements: Facilitates adherence to local regulations (e.g., tax deadlines, contracts) that may mandate Jalali dates, mitigating legal risks in regulated industries.
• User Experience (UX) Optimization: Improves engagement by displaying dates in the local calendar format (e.g., ۱۴۰۳/۰۵/۲۰ instead of 2024-08-10), which aligns with user expectations and reduces cognitive load for Persian-speaking audiences.
• Developer Efficiency: Accelerates development for date-related features (e.g., event scheduling, age verification, expiry notifications) by providing built-in validation, formatting, and Carbon-compatible methods, reducing technical debt.
• Roadmap for Multilingual Apps: Supports localized date displays (e.g., Persian/Arabic month names) and integrates with Laravel’s validation system, enabling scalable expansion into non-English markets with minimal refactoring.
• Build vs. Buy Decision: Justifies adoption over custom solutions due to its MIT license, active maintenance (last release: 2026), and Laravel-native design, ensuring long-term viability without reinventing core date logic.
• Key Use Cases:
  • E-commerce: Localize product expiry dates, shipping deadlines, or promotions for Persian markets.
  • HR/Payroll: Process holidays (e.g., Persian New Year), employee birthdays, or leave requests in Jalali dates.
  • Government/Compliance: Handle deadlines, licenses, or legal documents requiring Jalali formatting.
  • Content Platforms: Display blog posts, events, or news in localized date formats for Persian-speaking users.
  • Finance: Align fiscal year calculations or reporting periods with regional standards (e.g., Iranian fiscal year starting March 21).

When to Consider This Package

• Adopt if:

  • Your app targets Persian-speaking regions (Iran, Afghanistan, Tajikistan) or requires Jalali calendar support for compliance/UX.
  • You need seamless integration with Laravel/Carbon, minimizing refactoring for existing date logic.
  • Your team prioritizes developer velocity over custom solutions, given the package’s mature feature set (validation, localization, formatting).
  • You require bidirectional date conversion (Gregorian ↔ Jalali) with human-readable diffs (e.g., "۱ سال قبل").
  • Your roadmap includes multilingual support, and the package’s localization features align with your needs.

• Avoid if:

  • Your app exclusively serves Gregorian-calendar markets (e.g., US, EU), where Jalali support adds unnecessary complexity.
  • You need high-precision financial date calculations (e.g., interest accrual, trading systems). While Verta handles conversions well, specialized libraries may be required for complex arithmetic.
  • Your team lacks PHP/Laravel expertise, as the package assumes familiarity with Carbon and Laravel’s validation system.
  • You require timezone-aware Jalali dates (Verta focuses on date conversions, not timezones).

• Look Elsewhere if:

  • You need support for multiple calendar systems (e.g., Hebrew, Islamic). Verta is Jalali-specific; consider broader libraries like spatie/calendar for multi-calendar apps.
  • Your app uses non-Laravel PHP frameworks (e.g., Symfony, WordPress). Portability may require additional wrappers or abstractions.
  • You require advanced date math (e.g., astronomical calculations, custom fiscal years) beyond standard Jalali/Gregorian conversions.

How to Pitch It (Stakeholders)

For Executives:

*"Verta is a turnkey solution to integrate the Persian (Jalali) calendar into our Laravel application, unlocking growth in key markets like Iran and Afghanistan. By displaying dates in the local format (e.g., ۱۴۰۳/۰۵/۲۰ instead of 2024-08-10), we can:

• Boost engagement in Persian-speaking regions by aligning with user expectations (anecdotal data shows 20–30% higher conversion rates for localized date displays).
• Ensure compliance with regional regulations (e.g., tax filings, contracts) that mandate Jalali dates, reducing legal risks.
• Accelerate development for date-heavy features (e.g., event scheduling, expiry notifications) with built-in validation and formatting, saving ~3–5 dev weeks vs. a custom build.

The package is MIT-licensed, actively maintained (last release: 2026), and integrates seamlessly with our existing Carbon-based date logic, requiring minimal effort for maximum impact. For a zero-cost investment, we gain a competitive edge in a high-growth market."*

Key Metrics to Track:

• User Retention: Compare engagement metrics (e.g., session duration, form completion) before/after Jalali localization.
• Compliance: Audit rate of errors/non-compliance in regions requiring Jalali dates.
• Developer Productivity: Measure time saved on date-related features (e.g., validation, formatting).

For Engineering Teams:

*"Verta extends Laravel’s Carbon with Jalali calendar support, giving us the following capabilities with minimal overhead:

Core Features:

1. Seamless Conversion:
   • verta('2024-08-10') → ۱۴۰۳/۰۵/۲۰
   • now()->toJalali() or verta()->toCarbon() for bidirectional compatibility.
2. Validation:
   • Built-in Laravel rules like jdate_before_equal for forms (e.g., ‘birthday must be before today’).
3. Localization:
   • Persian/Arabic date formatting (e.g., formatWord('l dS F') → ‘دوشنبه بیست و چهارم مرداد’).
4. Carbon Compatibility:
   • Uses familiar methods (addDays(), diffInMonths()) but with Jalali awareness.

Implementation Plan:

1. Installation:

   composer require hekmatinasser/verta
   

2. Replace Carbon with Verta in date-heavy features:

   // Before
   $gregorianDate = now();
   
   // After
   $jalaliDate = verta(); // Returns Jalali date by default
   $carbonDate = verta()->toCarbon(); // Convert back to Carbon
   

3. Update Validation:

   // Add to FormRequest or Controller
   'birthday' => ['required', 'jdate_before_equal:today'],
   

4. Localization: Set default locale:

   Verta::setLocale('fa'); // Persian
   // or
   Verta::setLocale('ar'); // Arabic
   

Trade-offs & Risks:

• Learning Curve: Teams new to Jalali calendars may need to review epoch differences and leap year rules (e.g., ۱۳۹۶/۱۴۰۴).
• Timezone Handling: Jalali dates lack timezone context by default. Ensure config/app.php uses the correct timezone (e.g., Asia/Tehran).
• Testing: Validate edge cases (e.g., leap years, negative dates) in CI. Example:

  $this->assertTrue(Verta::isLeapYear(1404)); // Persian leap year
  

• Alternatives: If we need broader calendar support later, we could extend Verta or evaluate spatie/calendar.

Recommendation:

Pilot Verta in a non-critical feature (e.g., Persian-language blog or support portal) to validate integration and performance before full rollout. Monitor:

• Bugs: Date conversion accuracy, validation edge cases.
• Performance: Impact on API response times for date-heavy endpoints.
• UX: User feedback on localized date displays.

Next Steps:

1. Spike: Implement Verta in a sandbox environment to test conversion accuracy and Carbon compatibility.
2. Documentation: Create internal docs for Jalali-specific quirks (e.g., fiscal year calculations).
3. Rollout: Phase adoption starting with high-impact features (e.g., checkout dates, event scheduling)."*

For Design/UX Teams:

*"Verta enables culturally resonant date displays for Persian-speaking users, which is critical for:

• Trust: Users in Iran/Afghanistan expect dates in the Jalali format (e.g., ۱۴۰۳/۰۵/۲۰). Gregorian dates can feel foreign or confusing.
• Accessibility: Localized month/day names (e.g., ‘مرداد’ instead of ‘August’) improve readability for non-technical users.
• Consistency: Aligns with regional conventions for holidays, deadlines, and notifications.

Design Considerations:

1. Date Pickers: Use Verta’s formatJalaliDatetime() to
