#  Customizing Submission Date Created and Modified Formats

In Convert Forms, every submission record has two system dates: **Date Created**, the date and time the submission was received, and **Date Modified**, the date and time the submission was last updated. These dates appear in various areas of the extension, including the Submissions list in the backend and in [export files](https://www.tassos.gr/docs/convert-forms/functionality/export-submissions) such as CSV.

## [How the Date Format Is Determined](#how-the-date-format-is-determined)

The format used to display these dates is controlled by Joomla's built-in `DATE_FORMAT_LC5` language string. This format is language-dependent and automatically adapts to the active backend language. For example:

 | Language | Default Format | Example Output |
|---|---|---|
| English (US) | Y-m-d H:i | 2026-03-02 14:30 |
| German (de-DE) | d.m.Y H:i | 02.03.2026 14:30 |

No additional configuration is needed — Convert Forms will automatically use the format appropriate for your site's active backend language.

## [Changing the Date Format](#changing-the-date-format)

If you want to use a custom date format, you can do so by creating a Joomla Language Override for the `DATE_FORMAT_LC5` string.

1. In the Joomla backend, navigate to System → Manage → Language Overrides.
2. Set the Language selector to your desired language (e.g., English (en-GB) — Administrator) and ensure Location is set to Administrator.
3. Click New to create a new override.
4. In the Language Constant field, enter: `DATE_FORMAT_LC5`
5. In the Text field, enter your desired date format using PHP date format characters. For example: `d/m/Y H:i`
    Save the override.

## [Notes](#notes)

- This article concerns only the submission's Date Created and Date Modified system dates. It does not affect the value stored or displayed by a [Date & Time Field](https://www.tassos.gr/docs/convert-forms/fields/date-time) placed inside a form — each Date/Time field has its own dedicated date format setting configured within the field's settings
- `DATE_FORMAT_LC5` is not specific to Convert Forms. It is a global Joomla language string used across the entire Joomla installation. Overriding it will affect all areas of your site that rely on this format, including the Users component (e.g., the Last Visit date in the user list), other third-party extensions, and any other Joomla core area that uses `DATE_FORMAT_LC5`. If you only want to change the date format within Convert Forms without affecting the rest of your site, this is currently not possible through a language override, as the override applies site-wide.
