# How to Get a Total Number of Days in a Month using built in Functions in C#?

Given a year Y and month M, the task is to get a total number of days in a month in C#.

Examples:

```Input: Y = 2020 N = 02
Output: 29

Input: Y = 1996 N = 06
Output: 30
```

Method 1: Using DateTime.DaysInMonth(year, month) Method: This method is used to get the number of days in the specified month and year.

Step 1: Get the year and month.

Step 2: The DateTime.DaysInMonth() is used to get the number of days in a month

```int days = DateTime.DaysInMonth(year, month);;
```

Step 3: This integer value is the number of days in the month.

Below is the implementation of the above approach:

## C#

 `// C# program to Get a Total Number ` `// of Days in a Month ` `using` `System;  ` `   `  `public` `class` `GFG{  ` `     `  `    ``// function to get the full month name  ` `    ``static` `int` `getdays(``int` `year, ``int` `month)   ` `    ``{  ` `        ``int` `days = DateTime.DaysInMonth(year, month); ` `         `  `        ``return` `days; ` `    ``}  ` `     `  `    ``static` `public` `void` `Main ()  ` `    ``{   ` `        ``int` `Y = 2020; ``// year ` `        ``int` `M = 02; ``// month ` `         `  `        ``Console.WriteLine(``"Total days in ("` `        ``+ Y + ``"/"` `+ M + ``") : "``+ getdays(Y, M));  ` `    ``}   ` `}`

Output:

```Total days in (2020/2) : 29
```

Method 2: Using CultureInfo.CurrentCulture.Calendar.GetDaysInMonth(year,month) Method: This method is used to get the number of days in the specified month and year. You need to use  System.Globalization namespace.

Step 1: Get the year and month.

Step 2: The CultureInfo.CurrentCulture.Calendar.GetDaysInMonth() is used to get the number of days in a month

```int days = CultureInfo.CurrentCulture.Calendar.GetDaysInMonth(year, month);;
```

Step 3: This integer value is the number of days in the month.

Below is the implementation of the above approach:

## C#

 `// C# program to Get a Total Number ` `// of Days in a Month ` `using` `System;  ` `using` `System.Globalization; ` `   `  `public` `class` `GFG{  ` `     `  `    ``// function to get the full month name  ` `    ``static` `int` `getdays(``int` `year, ``int` `month)   ` `    ``{  ` `        ``int` `days = CultureInfo.CurrentCulture. ` `        ``Calendar.GetDaysInMonth(year, month); ` `         `  `        ``return` `days; ` `    ``}  ` `     `  `    ``static` `public` `void` `Main ()  ` `    ``{   ` `        ``int` `Y = 2020; ``// year ` `        ``int` `M = 02; ``// month ` `         `  `        ``Console.WriteLine(``"Total days in ("` `        ``+ Y + ``"/"` `+ M + ``") : "``+ getdays(Y, M) ` `        ``+ ``" days"``);  ` `    ``}   ` `}`

Output:

```Total days in (2020/2) : 29 days
```
