Sort Posts in Ascending Date by Default

New guy and have spent several hours searching for an answer. What I’ve found is:

1. Samples of code to change – but I’ve been told it’s best not to change the WP code except as a last resort, and not having to change code is why I’m using WP ??

2. A couple old plugins that haven’t been updated in a long time.

This is such a common request, I’m sure there must be a plugin that enables sorting of posts and archives in ascending chronological order. Thanks for pointing me to it! EDIT: More accurately, what I’d like to do is control the sort order separately for Archives, and for the main page blog entries. If I could also control categories with the same tool it would be heaven! ?? Thanks again!
