She cancelled but offered to reschedule?

Anonymous
Trying to set a first date with a girl. She gave a pretty legit excuse and said she was really sorry and wanted a rain check and said how about the next weekend. I was chill with it, it didn't bother me, but I've been looking online and people are saying that if she reschedules she must not be all that interested. I just thought that stuff happens sometimes and that's life but maybe I'm naive. Is it a good sign if a girl offers to reschedule or is it one of those "too nice so waits till I give up" type of things?

So is it up to her to confirm the date when it comes up or up to me? I don't know, I just have a feeling she might forget (might be lack of confidence). I'm picking her up.
