A Tumblr theme consists of three components: HTML, CSS and Tumblr's own custom variables. HTML creates a template that defines each element in the layout; CSS modifies the appearance of the objects on the page; and the custom variables add functions integral to the blogging platform. For example, "{block:Text}" creates a text entry on the page, and "{block:Title}" renders the title for the entry. Therefore, to remove the time stamp from your blog posts, you must delete the variable responsible for displaying the date and time.

Step 1

Log in to your Dashboard, and then click the gear icon to go to Settings.

Step 2

Choose your blog from the left, and then click "Customize" next to Theme. In the left pane, click "Edit HTML."

Step 3

Press "Ctrl-F," type "{block:Date}" (without quotes) into the search field, and then press "Enter." Highlight all of the text between and including the "{block:Date}" and "{/block:Date}" tags, and then press "Delete" on your keyboard.

Step 4

Click "Update Preview" to review your changes, and then click "Save" to remove the time stamp from your posts.

Step 5

Click the back arrow, and then click "Exit" to return to your Dashboard.
