ON the online Quasar Doc site, left side drawer, under Vue Components => Form Components => Date Picker => With QInput. The example input is 2019/02/01 which validates to true. The docs says the default modal format is YYYY/MM/DD.

Try entering 2019/02/32 validates true. Incorrect February has at most 29 days
try entering 2019/02/40 validates false. Correct.
Try entering 2019/13/01 validates true. Incorrect. Only 12 months in a year
Try entering 2019/21/01 validates false. Correct

The Template shows :rules="[‘date’]". Is there a better built-in, internal rules validation that will do a better job of validating dates?

Thanks
