If your Ghost CMS blog using Handlebars theme shows published date in relative time (like Published 11 months ago), you will find a handlebars code like this in your theme file.

<time datetime="{{date format="YYYY-MM-DD"}}">
    {{date published_at timeago="true"}}

Show exact date

The date published_at timeago="true" is responsible for the relative time. Change it to this.

<time datetime="{{date format="YYYY-MM-DD"}}">
    {{date published_at format="MMMM DD, YYYY"}}

This will give something like September 7, 2000.

Show exact time

You can use moment.js syntax for fine-tuning the details.

<!-- 2000 September 07 9:00:00 PM -->
<time datetime="{{date format="YYYY-MM-DD hh:mm:ss A"}}">
    {{date published_at format="YYYY MMMM DD hh:mm:ss A"}}
<!-- 2000 09 07 9:00 PM -->
<time datetime="{{date format="YYYY-MM-DD hh:mm A"}}">
    {{date published_at format="YYYY MM DD hh:mm A"}}
<!-- 2000 09 07 21:00 -->
<time datetime="{{date format="YYYY-MM-DD hh:mm"}}">
    {{date published_at format="YYYY MM DD hh:mm"}}

For months, use MM for short notations (like 09) and MMMM for longer notations (like September.) If you want to display time, the basic syntax is hh:mm:ss A for hours, minutes, seconds, and AM/PM. I am using the following.

<time datetime="{{date format="YYYY-MM-DD h:mm A"}}">
    {{date published_at format="YYYY/MM/DD h:mm A"}}
