Date Attribute

How it works

Use the date attribute to store important timestamps such as First Purchase Date, Last Checkout Date, or Last Visit Date.

The date attribute is available for the event, visit, and visitor scopes.

Date formatter

To convert a string attribute to a date, use the date formatter. Select the timestamp components from the date format panel that match the string values. For example, a string value such as 01/31/2020 can be converted to a date using a format of MM/dd/yyyy.

Date and time string patterns:

For more information, see Oracle: SimpleDateFormat Java Class.

If the string includes a T, include single quotes before and after the T in the expression. For example, a 2024-08-22T10:24:58.905 string uses the expression yyyy-MM-dd'T'HH:mm:ss.SSS. Omitting the quotes, such as using yyyy-MM-ddTHH:mm:ss.SSS, results in a parsing error.

Collect date values as string attributes

It is a best practice to collect date values as string event attributes and then use an enrichment to convert them to a date visitor attribute. This approach minimizes the risk of errors caused by incorrect formats, which could disrupt data collection and processing in downstream database systems. Importing as a string ensures greater flexibility and data integrity, especially when handling diverse date formats.

Example

To capture a signup date as a string and enrich a date attribute, use the following steps:

1. Create the Signup Date event attribute as a string, such as "2023-10-15".
2. Create the Signup Date visitor attribute as a date.
3. Use the Set Date enrichment on the visitor attribute to convert the string into a date attribute using the format yyyy-MM-dd.

Size Limits

The size of a each date attribute is limited to the following range:

• Minimum: -292275055-05-16T16:47:04.192Z
• Maximum: +292278994-08-17T07:12:55.807Z

These attributes are also limited by the maximum size of the profile after encryption and compression (400 KB).

Enrichments

Capture date

The Capture Date enrichment sets the attribute to the current timestamp at the time of an event condition. This enrichment is available for event, visit, and visitor attributes.

For example, to capture the Last Purchase Date, use this enrichment with a rule that identifies a purchase event.

Attribute Name: Last Purchase Date

• Starting Value: ""
• Enriched With:
• Resulting Value: 1491233145706

Set date

The Set date enrichment sets the attribute to the value of another attribute. If the other attribute is a string, use the Date Formatter to convert it to a date. This enrichment is available for event, visit, and visitor attributes.

Attribute Name: Last Purchase Date

• Starting Value: ""
• Enriched with String: 01/04/2019
• Using Format: dd/MM/yyyy (This format specifies the day, month, and year order for parsing the string.)

When you use the Set date enrichment to set an EventStream date from another date attribute (EventStream or AudienceStream), you can use a placeholder for the format string. For example, in the Set Date enrichment, set the following:

• Set date to: The date attribute you want to set the value to. In this example,date_of_birth.
• with date format: Enter any placeholder, for example, x.

Remove date

The Remove date enrichment erases the value of a date attribute. This enrichment is available for event, visit, and visitor attributes.

Attribute Name: Last Visit Date

• Starting Value: 1491233145706
• Resulting Value: (Removed)

Convert from date format

The Convert from date format enrichment sets the value based on an expected date format of incoming values. This enrichment is used to convert string values sent from the Collect tag or HTTP API. Use the Date Formatter to convert the string value to a date. This enrichment is available for event attributes.

Stitching merge rules

Stitching merge rules (if enabled) are optional, per‑attribute rules that determine the final value of an attribute when two visitor profiles are stitched.

The date attribute supports the following stitching merge rules:
