# Error: error:datefmt
Model is not a date object

## Description

All date-related inputs like `<input type="date">` require the model to be a `Date` object. If the model is something else, this error will be thrown. Angular does not set validation errors on the `<input>` in this case as those errors are shown to the user, but the erroneous state was caused by incorrect application logic and not by the user.
