Remove date on homepage

I’m not sure about the seamless look but try creating and activating a child themes of Writr and put this in the new wp-content/themes/writr-child/style.css file.

/*
 Theme Name:   Writr Child
 Description:  Writr Child Theme
 Template:     writr
 Version:      1.0.0
*/

@import url("../writr/style.css");

li.date-meta {
display: none;
}

Or consider using a custom CSS plugin and just put this CSS into it.

li.date-meta {
display: none;
}

This plugin is pretty good for that.
