Hey there, @scollrocker!
Thank you for reaching out to us about this. Are you referring to Jetpack’s Top Posts & Pages widget? If so, we have a pre-made code snippet for this:
– https://developer.jetpack.com/2016/01/28/top-posts-pages-widget-remove-all-popular-posts-that-werent-published-within-the-last-month/
The above snippet will restrict the Top Posts/Pages widget to posts published within the last month.
You do not need to code, and we also have a helpful guide that details how to use the above snippet:
