小博士：仔细观察下面这段对话，你会发现下面的句子中出现了已经学过的现在进行时，我们已经学过现在进行时是用于表示正在发生或进行的事情。可是用这个观点来解释下面这段对话却有些不通，这是怎么回事？请同学们仔细思考后来回答问题。
A：Hi, Tom, what day is it today?
B/C/D：Today is Thursday.
A：Can you come over to my house on Saturday?
B：OK, I'd love to.
C：I'm sorry, I can't. I'm having a piano lesson.
D：I'm sorry, too. I'm looking after my grandparents.
问：此处的现在进行时是用来表示此刻正在发生的事情吗？如果不是，那么此处的进行时是用来表示什么时候发生的事情呢？
