# Date Revision The system automatically indicates when a date has been revised. {% hint style="info" %} A date is considered revised when a user enters a date that is in the future. In this case, a green badge is displayed next to the date to clearly indicate that the date has been manually revised (see Figure 1). {% endhint %}

## Automatic locking To prevent unintended changes, automatic locking of revised dates can be enabled in the [System Settings.](/release-8.25/voyage-management-system/step-by-step-guides/setup/system-settings/general.md#breakdown-of-the-available-settings) When enabled, the system will: * Display the revision badge * Automatically lock the date field when a future date is entered This ensures that revised dates are clearly identifiable and protected from accidental edits (see Figure 2). {% hint style="warning" %} Note: Changing this setting only affects dates that are modified after the setting is enabled. {% endhint %}

## Un-revising a Date The method for removing the revised status depends on whether automatic locking is enabled. ### **When the setting is disabled** The only way to un-revise a date is to change it to a past date. Once the date is no longer in the future, the revision indicator will be removed. ### **When the setting is enabled** Revised dates are locked by default. To remove the revised status: 1. Click the **lock icon** to unlock the date. 2. The date returns to system-calculated behavior Unlocking the date removes the revision status and allows the system to calculate the date automatically again. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
