Date attribute
Store a date value
A Date attribute can store a single date in ISO 8601 format: yyyy-mm-dd
Configuration
When adding or editing a Date attribute on a design/interface, you can configure the following properties. These determine how the attribute will behave when users populate its value on corresponding items.
- 
Name * - enter a distinct name that clearly identifies the attribute. 
- 
Required - if enabled, the attribute will need to be populated with a value before the item can be saved. It can't be left blank! 
- 
Read-only - if enabled, the attribute can only be populated when creating items. It can't be edited later! 
- 
Unique - if enabled, the attribute won't accept a value that's already stored in the same attribute on another item of this design/interface. 
- Default value - the attribute will automatically be populated with this value, which can usually be changed before saving (unless it's Read-only or excluded from an item form).
- 
Min - the attribute won't accept a value occurring before this date. 
- 
Max - the attribute won't accept a value occurring after this date. 
- 
Tags - use the Tag Manager to select a custom tag or relevant system tag. 
Populate the attribute on items
When creating or editing an item, select the attribute to enter a value using the calendar picker. Select Save to finish.
