If you would like to change the date of a blog post on Squarespace, there are a few different ways that you can do this. The first way is to go to your blog post’s Edit page and under the Date heading, select the date that you would like to change it to.
You can also change the date by clicking on the calendar icon next to the Date header and selecting a new date from the calendar.
If you would like to change the date of a blog post but don’t have access to the Edit page or the calendar, you can also use the Date field in the Publish panel. To do this, first click on the Publish button at the top of your blog post’s page.
Then under the Published menu item, select Date. On the Date panel that appears, select a new date from the calendar or type in a new date into the text box.
