DateTime Field Type
Renders Gutenberg’s DateTimePicker component inside the block.
The type we would use inside the schema’s field_meta property to render this field is “datetime”: "type": "datetime"
If you haven’t already, we suggest you read the “model.json file” and “Field Types” pages before continuing.
Minimum Schema needed to create the field
"event_date_and_time": {
"type": "object",
"field_meta": {
"type": "datetime",
"label": "Event Date and Time",
},
"default": {
"value": null
}
}
This snippet of code will generate a simple DateTime control. The field name will be “event_date_time”, its label will be “Event Date and Time” and it will have a value of null (no date and time selected) by default.
What it would look like inside the block in the editor.

Rendering field’s data on the front-end:
We would use the same property that’s present inside the “default” object; "value", in this case.
In latte, it would look something like this.
<div n:ifcontent>{$event_date_time['value']|date:'j. n. Y'}</div>
Note that we need to use latte’s |date filter to properly format the datetime.
To learn more about the formatting options that you can use, check the DateTime::format page from the official PHP documentation.
Additional / Optional field_meta properties
Besides the field_meta properties we saw above, DateTime Field Type has only two optional properties that all root level Field Types can have.
