Using Datejs - Get the day of the week

问题

I'm using http://www.datejs.com/. I must be missing it, but is there a way I can pass it the day/month/year and have it tell me that it's a Friday or Monday or whatever?

回答1:

You want:

.toString("dddd");

For example:

> Date.parse("1.16.2012").toString("dddd");
"Monday"

回答2:

If you want to know whether it is a particular day of the week, you could do this:

Date.parse("1.16.2012").is().monday()
