what's the difference between ''For the past weeks'' and ''For the last weeks'' ? My friends asked me why I was not hanging out with them a lot like before, I want to say that I've been working so much. But I don't know when to use ''for the past ...'' and ''for the last...'' , or which one is correct. I've been busy for the past (few) weeks. I've been busy for the last (few) weeks. My schedule got tight for the last/past weeks. I've got a pretty tight schedule for the past days/last days/in these days. Any suggestions are welcome. Correct me if I'm wrong. Thanks
