# Date Formats

*This article assumes that users have a thorough understanding of [Data Blocks](https://learn.assette.com/docs/data-block-basics/)*,*[Data Objects](https://learn.assette.com/docs/data-block-basics/) and the [Generation Screen](https://learn.assette.com/docs/the-generation-screen/). This article also assumes that a Data Block exists and the appropriate data for a date column is available.*

In Assette, when users create tables with dynamic text values that include dates, such as a Portfolio Activity table showing a date, these dates are displayed in a specific format. This article explains how users can modify these date formats to suit their needs. Currently, the Object Editor provides both standard and custom date formatting options.1

The Data Object Editor includes a range of predefined **standard formats**, in line with the .NET date format standards, ensuring locale support for accurate regional date representations. The ability to define a completely **custom user format** will provide even greater control over how dates are displayed within dynamic text values.

## Standard Date Formats

*Standard Date Formats are dynamically driven by the [Display Locale](https://learn.assette.com/docs/the-generation-screen/#display-locale) selection on the [Generation Screen](https://learn.assette.com/docs/the-generation-screen/) and automatically updated based on the selected locale. For information on how to create static date formats, please see Custom Date Formats.*

To begin, open the [Developer Tools](https://learn.assette.com/docs/developer-center-overview/) from the [Assette Navigation Bar](https://learn.assette.com/docs/assette-navigation-bar/). Next, locate the Data Object to modify and select **Edit**. Alternatively, users may [create a new Data Object](https://learn.assette.com/docs/creating-data-objects/)— though this requires that the user add the required Data Blocks and columns to continue.

Next, select **[Data Settings](https://learn.assette.com/docs/data-settings-tab/)** from the Design View Tab. Click on **Add Dynamic Fields** at top of the screen.

![Date Formats 3](https://learn.assette.com/wp-content/uploads/2024/12/image-34-1024x560.png)

In the resulting pop-up, check the box next **Language** and then click on **Add Selected** as shown below. The **Language**Data Setting is a dynamic value and does not need to be changed. Note however, that skipping this step may cause issues with subsequent steps.

![Date Formats 4](https://learn.assette.com/wp-content/uploads/2024/12/image-35.png)

Next, switch to the [**Columns Tab**](https://learn.assette.com/docs/columns-tab/). From here, select the column containing the dynamic date value, in this example, it's **Display Activity**, and choose **Edit**.

![Date Formats 5](https://learn.assette.com/wp-content/uploads/2024/12/Screenshot-2024-12-09-102059-1024x497.jpg)

This will open a popup where users should go to the **Value** tab. The **Output Type** mustbe set to **Dynamic Text** to continue. Next, press the **TX** icon on the right-hand side of the screen.

*Note that users may see multiple values here depending on the logic of Data Object— select the **TX** option next to the desired date value. Each dynamic must be set up independently.*

![Date Formats 6](https://learn.assette.com/wp-content/uploads/2024/12/Screenshot-2024-12-09-102221-1024x496.jpg)

A new popup will appear, showing the placeholder for the Begin or End Date.

![Date Formats 7](https://learn.assette.com/wp-content/uploads/2024/12/Screenshot-2024-12-09-102358.jpg)

Select a column with a **Date**Data Type. This can be done by using the filer or simply searching for "Date". Columns with a **Formatting**option, as shown below may be used. In this example, we will be using the **BeginDate** column. Click on **Formatting** to open the formatting options.

![Date Formats 8](https://learn.assette.com/wp-content/uploads/2024/12/Screenshot-2024-12-09-102511.jpg)
