 9 | This project is open source, and as such, the maintainers give their free time to build and maintain the source code
10 | held within. They make the code freely available in the hope that it will be of use to other developers. It would be
11 | extremely unfair for them to suffer abuse or anger for their hard work.
12 | 
13 | Please be considerate towards maintainers when raising issues or presenting pull requests. Let's show the
14 | world that developers are civilized and selfless people.
15 | 
16 | It's the duty of the maintainer to ensure that all submissions to the project are of sufficient
17 | quality to benefit the project. Many developers have different skillsets, strengths, and weaknesses. Respect the maintainer's decision, and do not be upset or abusive if your submission is not used.
18 | 
19 | ## Viability
20 | 
21 | When requesting or submitting new features, first consider whether it might be useful to others. Open
22 | source projects are used by many developers, who may have entirely different needs to your own. Think about
23 | whether or not your feature is likely to be used by other users of the project.
24 | 
25 | ## Procedure
26 | 
27 | Before filing an issue:
28 | 
29 | - Attempt to replicate the problem, to ensure that it wasn't a coincidental incident.
30 | - Check to make sure your feature suggestion isn't already present within the project.
31 | - Check the pull requests tab to ensure that the bug doesn't have a fix in progress.
32 | - Check the pull requests tab to ensure that the feature isn't already in progress.
33 | 
34 | Before submitting a pull request:
35 | 
36 | - Check the codebase to ensure that your feature doesn't already exist.
37 | - Check the pull requests to ensure that another person hasn't already submitted the feature or fix.
38 | 
39 | ## Requirements
40 | 
41 | If the project maintainer has any additional requirements, you will find them listed here.
42 | 
43 | - **[PSR-12 Coding Standard](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-12-extended-coding-style-guide.md)** - The easiest way to apply the conventions is to install [PHP Code Sniffer](http://pear.php.net/package/PHP_CodeSniffer).
44 | 
45 | - **Add tests!** - Your patch won't be accepted if it doesn't have tests.
46 | 
47 | - **Proper Method Signature and Its Default Values** - When modifying or adding methods, ensure that the method signatures are clear and concise. Provide default values for parameters when necessary, balancing flexibility with readability for a more maintainable codebase.
48 | 
49 | - **Method Name Consistency** - Maintain consistency in naming conventions for methods throughout the package. Consistent naming practices improve code cohesion and readability, facilitating a smoother collaborative development process.
50 | 
51 | - **Unnecessary Docblock** - Evaluate the necessity of docblock comments for methods. If a method's functionality is clear without additional explanation, consider omitting the docblock. This helps enhance code readability while preserving clarity.
52 | 
53 | - **README Updates** - Ensure the `README.md` is updated along with changes to the codebase. Reflect any modifications to method names or signatures, providing users with accurate examples and explanations for a cohesive experience.
54 | 
55 | - **Consider our release cycle** - We try to follow [SemVer v2.0.0](http://semver.org/). Randomly breaking public APIs is not an option.
56 | 
57 | - **One pull request per feature** - If you want to do more than one thing, send multiple pull requests.
58 | 
59 | - **Send coherent history** - Make sure each individual commit in your pull request is meaningful. If you had to make multiple intermediate commits while developing, please [squash them](http://www.git-scm.com/book/en/v2/Git-Tools-Rewriting-History#Changing-Multiple-Commit-Messages) before submitting.
60 | 
61 | **Happy coding**!

  6 | 
  7 | LaravelNepaliDate is a Laravel package that simplifies the conversion of dates between the Gregorian (English) and Nepali (Bikram Sambat) calendars. This package is a handy tool for projects that require handling dates in both English and Nepali formats, such as websites and applications targeting users in Nepal.
  8 | 
  9 | ## Installation
 10 | 
 11 | You can install the package via composer:
 12 | 
 13 | ```bash
 14 | composer require anuzpandey/laravel-nepali-date
 15 | ```
 16 | 
 17 | Optionally, you can publish the config file with:
 18 | 
 19 | ```bash
 20 | php artisan vendor:publish --tag="nepali-date-config"
 21 | ```
 22 | 
 23 | ## Usage
 24 | 
 25 | ```php
 26 | $engDate = '1996-04-22';
 27 | LaravelNepaliDate::from($engDate)->toNepaliDate();
 28 | // Result: 2053-01-10
 29 | 
 30 | LaravelNepaliDate::from($engDate)->toNepaliDate(format: 'D, j F Y');
 31 | // Result: सोम, १० वैशाख २०५३
 32 | 
 33 | // Format Specifiers are supported and listed below
 34 | LaravelNepaliDate::from($engDate)->toNepaliDate(format: 'D, j F Y', locale: 'en');
 35 | // Result: Mon, 10 Baisakh 2053
 36 | 
 37 | 
 38 | $nepDate = '2053-01-10';
 39 | LaravelNepaliDate::from($nepDate)->toEnglishDate();
 40 | // Result: 1996-04-22
 41 | 
 42 | LaravelNepaliDate::from($nepDate)->toEnglishDate(format: 'l, jS F Y');
 43 | // Result: Sunday, 22nd April 1996
 44 | 
 45 | // Format Specifiers are supported and listed below
 46 | LaravelNepaliDate::from($nepDate)->toEnglishDate(format: 'l, j F Y', locale: 'np');
 47 | // Result: आइतबार, २२ बैशाख १९९६
 48 | 
 49 | // Get total days in a month of a year
 50 | use Anuzpandey\LaravelNepaliDate\Enums\NepaliMonth;
 51 | // month can be NepaliMonth::XXX or month number (1-12)
 52 | LaravelNepaliDate::daysInMonth(NepaliMonth::BAISAKH, 2053);
 53 | // Result: 31
 54 | 
 55 | // Get total days in a year
 56 | LaravelNepaliDate::daysInYear(2053);
 57 | // Result: 365
 58 | ```
 59 | 
 60 | ## Format Specifiers
 61 | 
 62 | The following format specifiers are supported for formatting dates:
 63 | 
 64 | - `Y` - Year in four digits
 65 | - `y` - Year in two digits
 66 | - `m` - Month in two digits with leading zero (01-12/०१-१२)
 67 | - `n` - Month in one or two digits without leading zero (1-12/१-१२)
 68 | - `M` - Month in three letters (Jan-Dec)
 69 | - `F` - Month in full name (January-December/बैशाख-चैत्र)
 70 | - `d` - Day in two digits with leading zero (01-31/०१-३२)
 71 | - `j` - Day in one or two digits without leading zero (1-31/१-३२)
 72 | - `D` - Day in three letters (Sun-Sat/आइत-शनि)
 73 | - `l` - Day in full name (Sunday-Saturday/आइतबार-शनिबार)
 74 | - `S` - Day in two letters (st, nd, rd, th)
 75 | 
 76 | ## Extending Carbon with NepaliDateMixin
 77 | > **Note:** This feature has been deprecated as Carbon doesn't support the months having more than 31 days. This feature has been removed from version 2.0.0.
 78 | 
 79 | ### Helper function
 80 | 
 81 | ```php
 82 | // Convert English date to Nepali date (B.S.).
 83 | toNepaliDate("1996-04-22") 
 84 | // Result: 2053-01-10
 85 | 
 86 | // Convert Nepali date to English date (A.D.).
 87 | toEnglishDate("2053-01-10") 
 88 | // Result: 1996-04-22
 89 | ```
 90 |
