Dingo API pass array or multiple models

this is my input data for the transformer.

array:3 [▼
  0 => {#405 ▼
    +"day": 24
    +"month": 5
    +"name_cz": "Jana"
  }
  1 => {#404 ▼
    +"day": 24
    +"month": 6
    +"name_cz": "Jan"
  }
  2 => {#406 ▼
    +"day": 6
    +"month": 7
    +"name_cz": "Upálení mistra Jana Husa"
  }
]

And this is my transformer $this->item($dates, new DateTransformer());

I need to pass this data to the transformer and process it nut array is not accepted by transformer. How can I pass data to the transformer or multiple instances of Eloquent? Thank you
