If you want to know what changed on a branch since last week, you can more or less ask just like that:
$ git log --since="1 week ago"Or, what has happened since yesterday:
$ git log --after="yesterday"The --since/--after flags, and their counterparts --until/--before,
accept a variety of date formats including relative dates.
Relative dates can be used with other commands and even as a ref modifier. For
instance, this is a way of comparing develop from a week ago with develop
from two weeks ago:
$ git diff develop@{"1 week ago"} develop@{"2 weeks ago"}
