Modified Date

Works like a charm, Thanks Leo! (again)

No problem :)

Is there a way I can exclude the update stamp from certain pages? i.e. I would like to eliminate the stamp from my contact page. Thanks in advance!

If you use are using Tom's Simple CSS: https://docs.generatepress.com/article/adding-css/#simple-css
It gives you a CSS metabox on each page, then you can use this CSS:

.posted-on .updated {
    display: none;
}
