There are two reasons why your date picker property may not appear as an option when copying property values in a workflow:
The source property is datetime and the target property is date
There are two types of date picker properties in HubSpot: date and datetime:
- Date properties can only store information at the date level. For example, a date property value is Feb 2, 2017 (date only).
- Datetime properties can store information at the date and time level. For example, a datetime property value is Feb 2, 2017 (date) at 5:04:13 PM (time).
All of HubSpot's default date properties such as Create Date and Last Modified Date are datetime properties, while all custom-created date picker properties are date properties. It is only possible to create or update datetime properties via the HubSpot API.
In order to copy a date picker property value into another date picker property, the two property types must match, or the source property must be a date property and the target property must be a datetime property. It is not possible to copy values from datetime properties to date properties because the date properties can't store the same timestamp.
The target property is read-only
If the two date properties meet the conditions above, you may still notice some date picker properties not appearing as a target property option. This occurs when the target property is read-only.
Read-only properties are typically set by HubSpot or third-party integrations and cannot be manually edited. For example, it is not possible to modify the Create Date of a contact as this is automatically set when the contact is created in HubSpot.
