UC知道C#隐式枚举转换问题！

using System
enum Weekday
{Sunday,Monday,Tuesday,Wednesday,Thursday,Friday,Saturday};
class Test
{
public static void Main()
{
Weekday day;
day=0;
Console.WriteLine(day);
}
}
程序输出是：0
但是如果我们把语句day=0改写day=1，编译器就会给出错误：
Can not implictly convert type ‘int’ to type ‘enum’
我想知道为什么改写后会出错？同时希望大家帮我把上面语句写下注释！
谢谢！！！

using System;
public class EnumTest
{
enum Days {Sat=1, Sun, Mon, Tue, Wed, Thu, Fri};
static void Main()
{
int x = (int)Days.Sun;int y = (int)Days.Fri;
Console.WriteLine("Sun = {0}", x);
Console.WriteLine("Fri = {0}", y);
}
}
Sun = 2
Fri = 7
