I spent the whole afternoon chatting with friends. ✬

Judging from the look of the sky, it will clear up in the afternoon. ✬

The meeting ended at three in the afternoon. ✬

The meeting will be held this afternoon. ✬

It was a very pleasant afternoon. ✬

By the way, are you free this afternoon? ✬

Please come to my house in the afternoon. ✬

Let's make it Monday afternoon. ✬

Come on Monday afternoon, if possible. ✬

I'm going to go to the doctor this afternoon. ✬
