Get posts from the last X days

Is it possible to get posts from the last X days? Using helper #get or another resource?

This gets the five most recent posts:

{{#get "posts" limit="5" order="published_at desc"}}{{/get}}

You could also use a filter setting in your get to filter by published_at, but you’ll need to dig into the docs about formatting - I don’t have it at my fingertips.
