# Customize Date Fields in Deliver

You can change the way that dates are displayed in-line in a Deliver mailing using Liquid Markup.

> [!NOTE]
> 💡 Have access to the query?
> 
> Instead of formatting merge fields with Liquid Markup, you can set a date's Format Mask by editing the export directly. This approach works well when you want the same date and time formatting applied to all date fields in your mailing.

1. Click **Deliver** in the top navigation bar.
2. Click on the mailing to be formatted.
3. Click on **Edit Message** to access the HTML editor popup.
4. Click the **Source** icon in the HTML editor toolbar to display the mailing’s source code.
5. Find the date/time merge field and set your cursor within it after the merge field’s title.
6. Add a space, a vertical bar (pipe delimiter), a space, the word “date”, a colon, and another space inside the curly brackets.
  1. For example, the merge field `{{HSV-Date}}` becomes `{{HSV-Date | date: }}`.
7. Finish amending the merge field by adding your preferred format from the list below.

### Date/Time Format Examples

For these examples, we will use a sample merge field called `{{HSV-Date}}`.

Example 1 will change your date and time to look like: Monday, July 7 at 9:00 AM

```plainText
{{HSV-Date | date: "dddd, MMMM d 'at' h:mm tt"}}
```

Example 2 will change your date and time to look like: Mon, Jul 07 at 9:00 AM

```plainText
{{HSV-Date | date: "ddd, MMM dd 'at' h:mm tt"}}
```

Example 3 will change your date and time to look like: 07-07-2019

```plainText
{{HSV-Date | date: "MM-dd-yyyy"}}
```

Similar to Conditional Logic, Liquid Markup allows text or images to be displayed or hidden based on defined criteria. Liquid Markup offers more nuance that Conditional Logic and is generally recommended for more complex logic.

Format masks can be placed on form fields to ensure that data is entered and formatted consistently. For example, a GPA field may be restricted to only numeric data with two digits following the decimal point. In other examples, a field format may include a currency with a thousands separator, or a field may force the input to be in the form of an email address.
