编写一个具有如下功能的万年历与日历查询系统：显示某一年的全年日历（每天要有对应的星期）；显示任意指定某年某月的月历（每天要有对应的星期）；显示某年某月某日是星期几；显示某年某月某日是该年的第几天，已知1980年1月1日为星期二。

好的，以下是万年历与日历查询系统的代码实现。

    }

关于中文加密，由于不知道你需要的是哪种加密方式，无法给出具体答案。而对于 "lua closure factory 完整代码" 这个问题，以下是一个简单的例子：

-- 闭包工厂，用于创建计数器
function createCounter()
    local count = 0
    -- 返回一个匿名函数作为计数器
    return function ()
        count = count + 1
        return count
    end
end

-- 创建两个计数器
counter1 = createCounter()
counter2 = createCounter()

-- 分别使用两个计数器
print(counter1()) --> 1
print(counter1()) --> 2
print(counter2()) --> 1
print(counter2()) --> 2
print(counter1()) --> 3
