I find it varies with the work being done vs. relating to a discrete time duration. In general, I try to be very atomic. As an added benefit, this makes it simpler for someone doing a git bisect later. Fixing minor typos or copy changes across a few files could result in several commits within 15 minutes. Working on a major feature that requires research and definition and a lot of conversation or feedback, might mean a few commits over the span of a few days.
