Archives.php is a template file that WordPress will use by default (if it exists). If you want to create a custom page template you need to create a new template file in your theme. You can read all about it [here][1], but I'll provide an example below. Put this at the top of your new file:

`
<?php
/*
Template Name: Your page template name goes here.
*/
?>
`

...then follow it with the custom code you need to display your data.

Then, when creating a new page that you would like to use the above template, you will see a drop-down list on the right that lists all the names of page templates you have in your theme.
