# Publication date

## Publication date and Date added

The publication date is the date on which a file was activated, i.e. put online and visible in the gallery. The newness of a file is defined according to the publication date.

This is not to be confused with the "Date added", which corresponds to the date on which the file was added to the database following a scan of the album directory or upload by the browser.

Suppose you add a file without the "Activate files" option. In this case, the file will have an date added but no publication date. If you activate this file later, the publication date will be set to the precise moment when you activated it, even without using the "Reset publication date" option.

## Schedule file activation

You can schedule the activation of deactivated files by specifying a future publication date.

To program the activation of an album or an entire category, follow these steps:

1. With the "grid" display mode, go to the album or to the "Manage files" section of the category.
2. Use the "Select all" selection tool.
3. Go to the "Selection" tab, then to "Dates" and set a publication date.

The album or category, with all its files, will thus be activated on the date indicated.
