翻译：How I would change it would be to make it my...

Which day of a week would you like to change, and how would you want to make the change?

The day I would most like to change is Monday--because it seems to be the most hectic. How I would change it would be to make it my personal off-day.

请问最后一句如何理解呢？

how I would change it为名词性关系分句，how没疑问含义。how=the way in which

to make it my personal off-day为不定式作确认性表语。主语A=表语B。主语和表语可以互换句法功能，即主语作表语，表语作主语。意义不变。
