DateTime now = DateTime.Now;

int shamsiYear = persianDate.GetShamsiYear(now);
string shamsiMonthName = persianDate.GetShamsiMonthName(now);

// Output: Short Day Name: سه‌

✨ Enhanced Formatting Options (New in v1.9.3)

Multiple Format Styles

using PersianDate;

DateTime date = new DateTime(2024, 3, 20);

// Predefined format styles
string short = ShamsiDateFormatter.Format(date, ShamsiFormatStyle.Short);
// Output: ۱۴۰۳/۱/۱

string medium = ShamsiDateFormatter.Format(date, ShamsiFormatStyle.Medium);
// Output: ۱ فرو ۱۴۰۳

string long = ShamsiDateFormatter.Format(date, ShamsiFormatStyle.Long);
// Output: ۱ فروردین ۱۴۰۳

string full = ShamsiDateFormatter.Format(date, ShamsiFormatStyle.Full);
// Output: چهارشنبه، ۱ فروردین ۱۴۰۳

Custom Format Patterns

// Custom patterns with Persian digits (default)
string custom1 = ShamsiDateFormatter.Format(date, "yyyy/MM/dd");
// Output: ۱۴۰۳/۰۱/۰۱

string custom2 = ShamsiDateFormatter.Format(date, "dddd، dd MMMM yyyy");
// Output: چهارشنبه، ۰۱ فروردین ۱۴۰۳

// English digits
string english = ShamsiDateFormatter.FormatWithEnglishDigits(date, "yyyy/MM/dd");
// Output: 1403/01/01

Time Formatting

DateTime dateTime = new DateTime(2024, 3, 20, 14, 30, 45);

string withTime = ShamsiDateFormatter.Format(dateTime, "yyyy/MM/dd HH:mm:ss");
// Output: ۱۴۰۳/۰۱/۰۱ ۱۴:۳۰:۴۵

string timeOnly = ShamsiDateFormatter.FormatTime(dateTime, "HH:mm");
// Output: ۱۴:۳۰

🔍 Date Parsing and Validation (New in v1.9.3)

Parse Persian Date Strings

using PersianDate;

// Parse various formats
DateTime parsed1 = ShamsiDateParser.Parse("۱۴۰۳/۱/۱");
DateTime parsed2 = ShamsiDateParser.Parse("1403/1/1");
DateTime parsed3 = ShamsiDateParser.Parse("1403-01-01");

// Safe parsing with TryParse
if (ShamsiDateParser.TryParse("۱۴۰۳/۱۲/۲۹", out DateTime result))
{
    Console.WriteLine($"Parsed: {result}");
}

// Strict validation
var validation = ShamsiDateParser.ParseAndValidate("1403/13/1");
if (!validation.IsValid)
{
    Console.WriteLine($"Error: {validation.ErrorMessage}");
    // Output: Error: Month must be between 1 and 12
}

Validation Options

// Different validation modes
bool isValid1 = ShamsiDateParser.IsValidShamsiDate(1403, 12, 30); // false (invalid day)
bool isValid2 = ShamsiDateParser.IsValidShamsiDate(1403, 6, 31);  // false (month 6 has max 31 days)
bool isValid3 = ShamsiDateParser.IsValidShamsiDate(1403, 1, 31);  // true

// Parse with custom validation
var strictResult = ShamsiDateParser.ParseAndValidate("1403/12/30", ValidationMode.Strict);
var lenientResult = ShamsiDateParser.ParseAndValidate("1403/12/30", ValidationMode.Lenient);

🌐 Localization and Culture Support (New in v1.9.3)

Persian Culture

using PersianDate;

DateTime date = new DateTime(2024, 3, 20);
var persianCulture = ShamsiCultureInfo.Persian;

// Persian formatting with Persian digits and month names

// Output: ۰۱ فروردین ۱۴۰۳

// Extension method for Persian culture
string persianExt = date.ToShamsiString(ShamsiFormatStyle.Long, persianCulture);
// Output: ۱ فروردین ۱۴۰۳
