# MoveDate

{% hint style="info" %}
The **`MoveDate()`**function shifts a date by a given amount of a date unit.

This function is SQL compatible. For more information about SQL compatibility, see our [documentation](/platform/wemreference/sql-compatibility.md).
{% endhint %}

{% hint style="success" %}
Returns a new <mark style="color:green;">date</mark> where a number of units is added/subtracted to/from a date.

Returns <mark style="color:red;">**`Unknown`**</mark> if one of the parameter values is unknown or outside the common valid date boundaries.
{% endhint %}

{% hint style="danger" %}
*Although MoveDate() IS SQL Compatible - meaning it will be used on the database to return a smaller resultset, it may be slow in execution on the database, depending on the situation (number of records, distribution over data-pages, the filter in total with maybe other fields) where SQL may not be able to optimize the execution plan...*&#x20;
{% endhint %}
