perl_fool ("a biotechnology student who is forced to study programming for god's sake!!" according to your self-description):

    Does that mean you believe programming is beneath you? That even a one-glance nod at html instructions is an inappropriate demand upon "a biotechnology student?"

sorry i dunno the html formatting

Did you even look at the instructions on the page where you entered your question?

And if you can't be troubled to research that (ie, read the notes above and the warnings below the text input box), why should we write code for you?

But you did some research on the problem itself... you said so:

I've looked through the calendar examples in this website but it's too hard for me, especially the use of local time function.

Oh....

  :-(

Same basic issue: lack of effort. So, since creating this kind of simple calendar is an often-solved task... as far as I'm concerned, it's currently yours alone; that is, beyond filling in the details in your supposed "guideline" (which, you're right, won't work, as is... but if it would, it wouldn't be a mere guideline).
