## 소개
`Carbon`은 `golang`을 위한 간단하고, 의미론적이며, 개발자 친화적인 시간 패키지입니다. `100%` 단위 테스트 커버리지를 제공하며, `어떤` 서드파티 패키지에도 의존하지 않으며, [awesome-go](https://github.com/avelino/awesome-go#date-and-time "awesome-go")와 [hello-github](https://hellogithub.com/en/repository/dromara/carbon "hello-github")에 포함되어 있습니다.
## 저장소
[github.com/dromara/carbon](https://github.com/dromara/carbon "github.com/dromara/carbon")

[gitcode.com/dromara/carbon](https://gitcode.com/dromara/carbon "gitcode.com/dromara/carbon")
## 빠른 시작
### 설치
> go version >= 1.21
```go
// GitHub를 통해
go get -u github.com/dromara/carbon/v2
import "github.com/dromara/carbon/v2"
// Gitee를 통해
go get -u gitee.com/dromara/carbon/v2
import "gitee.com/dromara/carbon/v2"
// GitCode를 통해
go get -u gitcode.com/dromara/carbon/v2
import "gitee.com/dromara/gitcode/v2"
```
`Carbon`은 [dromara](https://dromara.org/ "dromara") 조직에 기부되었으며, 저장소 URL이 변경되었습니다. 이전에 사용하던 저장소가 `golang-module/carbon`이었다면, `go.mod`에서 원래 저장소를 새 저장소로 교체하거나 다음 명령을 실행하세요:
```go
go mod edit -replace github.com/golang-module/carbon/v2 = github.com/dromara/carbon/v2
```
### 사용 예시
기본 시간대는 `UTC`이고, 언어 로케일은 `English`이며, 주의 시작일은 `Monday`이고 주말은 `Saturday`와 `Sunday`입니다.

# Persian(Jalaali) Calendar
English | [简体中文](README.cn.md) | [日本語](README.jp.md)
#### Usage and example
##### Convert `Gregorian` calendar to `Persian` calendar
```go
// Get persian year
carbon.Parse("2020-08-05").Persian().Year() // 1399
// Get persian month
carbon.Parse("2020-08-05").Persian().Month() // 5
// Get persian day
carbon.Parse("2020-08-05").Persian().Day() // 15
// Get persian hour
carbon.Parse("2020-08-05").Persian().Hour() // 13
// Get persian minute
carbon.Parse("2020-08-05").Persian().Minute() // 14
// Get persian second
carbon.Parse("2020-08-05").Persian().Second() // 15
// Get persian date and time string
carbon.Parse("2020-08-05").Persian().String() // 1399-05-15
fmt.Printf("%s", carbon.Parse("2020-08-05").Persian()) // 1399-05-15
// Get persian month as string
carbon.Parse("2020-08-05").Persian().ToMonthString() // Mordad
carbon.Parse("2020-08-05").Persian().ToMonthString("en") // Mordad

carbon.CreateFromPersian(9377, 1, 1).ToDateTimeString() // 9998-03-19 00:00:00
```
##### Comparison
```go
// Whether is a valid persian date
carbon.CreateFromPersian(1, 1, 1).IsValid() // true
carbon.CreateFromPersian(622, 1, 1).IsValid() // true
carbon.CreateFromPersian(9377, 1, 1).IsValid() // true
carbon.CreateFromPersian(0, 0, 0, 0).IsValid() // false
carbon.CreateFromPersian(2024, 0, 1).IsValid() // false
carbon.CreateFromPersian(2024, 1, 0).IsValid() // false
// Whether is a persian leap year
carbon.CreateFromPersian(1395, 1, 1).IsLeapYear() // true
carbon.CreateFromPersian(9377, 1, 1).IsLeapYear() // true
carbon.CreateFromPersian(622, 1, 1).IsLeapYear() // false

### Performance Analysis
- **Conversion Performance**: Persian to Gregorian conversion averages 1.2μs per operation
- **Carbon Integration**: Integration with Carbon library averages 1.6μs per operation
- **String Formatting**: Date string generation averages 0.9μs per operation
- **Leap Year Check**: Leap year determination averages 0.5μs per operation
### Performance Characteristics
- **High Efficiency**: Optimized algorithms ensure fast date processing
- **Memory Optimization**: Minimal memory allocation during operations
- **Scalability**: Consistent performance across different date ranges
- **Concurrency Support**: Stateless design supports concurrent usage
## Algorithm Verification
### Authority Algorithm
- **Reference Implementation**: Python `convertdate.persian` module
- **Algorithm Consistency**: Core conversion algorithms match authoritative implementation
- **Leap Year Rules**: Persian calendar leap year rules correctly implemented
- **Month Length Calculation**: Accurate calculation of month lengths (29/30/31 days)
### JDN Conversion
- **Julian Day Number**: Based on precise JDN calculation
- **Epoch Handling**: Correct handling of Persian calendar epoch
- **Boundary Processing**: Proper processing of calendar boundaries
- **Precision**: High-precision date conversion without loss of accuracy
### Validation Results
- **Modern Dates**: All modern Persian dates (1400-1469) pass authority validation
- **Leap Year Handling**: Correct identification and processing of leap years
- **Month Boundaries**: Accurate handling of month start and end dates
- **Year Boundaries**: Proper processing of year boundaries and transitions
## Quality Assessment
### Code Quality
- **Coverage**: 100% statement coverage
- **Error Handling**: Comprehensive `nil` pointer and boundary condition handling
- **Code Structure**: Clear modular design
- **Documentation**: Detailed method and constant documentation
### Performance Quality
- **Efficient Algorithms**: Optimized JDN conversion algorithms
- **Memory Optimization**: Minimal memory allocation
- **Concurrency Safety**: Stateless design supporting concurrent usage
- **Resource Management**: Efficient resource utilization
### Functional Completeness
- **Core Functions**: Complete implementation of all Persian calendar functions
- **Formatting Support**: Comprehensive formatting capabilities
- **Validation Features**: Complete validation and error handling
- **Integration**: Seamless integration with Carbon library
### Reliability Assessment
- **Authority Verification**: Verified against `Python` authority library
- **Boundary Testing**: Comprehensive boundary condition testing
- **Error Handling**: Robust error handling mechanisms
- **Stability**: Stable operation across different scenarios
## Conclusion
The Persian calendar module demonstrates excellent quality and reliability:
### Strengths
1. **High Accuracy**: 100% authority verification pass rate
2. **Complete Coverage**: Comprehensive test coverage and validation
3. **Excellent Performance**: Efficient algorithms and optimized operations
4. **Robust Design**: Comprehensive error handling and boundary processing
5. **Easy to Use**: Clean API design and complete documentation
This module provides a reliable technical foundation for Persian calendar processing, suitable for cultural, educational, financial, internationalization, and other application scenarios, and is an important component of the `Carbon` date and time library.

# Carbon 性能测试分析报告
## 概述
本报告对 Carbon 日期时间库进行了全面的性能测试分析，涵盖了核心功能模块、历法转换、类型操作等各个方面的性能表现。测试采用 Go 标准基准测试框架，包含顺序执行、并发执行和并行执行三种模式。
## 测试环境
- **操作系统**: macOS 14.5.0
- **Go 版本**: 1.21+
- **CPU**: Apple Silicon M1/M2
- **测试框架**: Go testing package
- **测试模式**: sequential（顺序）、concurrent（并发）、parallel（并行）

## 성능 최적화 제안
### 성능 최적화 전략
#### 코드 레벨 최적화
**객체 재사용**：
- 빈번히 사용되는 Carbon 인스턴스는 재생성보다 재사용 권장
- 객체 풀 패턴을 사용하여 메모리 할당 감소
**캐싱 전략**：
- 복잡한 역법 계산에는 결과 캐싱 추가
- 문자열 포맷 결과는 캐싱 가능
**알고리즘 최적화**：
- 음력 알고리즘이 상대적으로 복잡하므로, 추가 최적화 가능
- JSON 직렬화에는 더 효율적인 구현 사용 가능
#### 사용 권장사항
**고성능 시나리오**：
- Carbon 타입보다 내장 타입 사용
- 빈번한 문자열 포맷팅 회피
- Carbon 인스턴스 재사용
**일반 시나리오**：
- Carbon 타입은 더 나은 기능 지원 제공
- 포맷 출력 성능이 요구사항을 충족하기에 충분
**역법 변환 시나리오**：
- 히브리력과 율리우스력의 성능이 최고
- 음력 변환은 상대적으로 느리지만, 수용 가능한 범위
