This issue can be reproduced with any field marked as required, not only Date field.
Problem rises from ctools entity form plugin, that leaves form in original untouched, hiding all fields except those who are added from panel. Therefore all fields would go through validation.

Thanks Temoor But This problem only for date filed. for test you can add text field on article and mark it as required and mark date field as optional and you see panels work properly.
one other point if you change required date field widget to select list you get this error:

A valid date is required for [mydatefieldname].
[mydatefieldname] field is required.

and if you change date field widget to popup, error message changed to:

A valid date is required for date.
