Date validations in a content type

[krishna kiriti]

Hello Team,

I tried searching for this question in this group but couldn't find it. 

I'm fairly new to this dotCMS and dojo. I want to know how can I implement date validations in dotCMS?

I have a date time field and I want to disable past dates and futures dates based on some criteria for that date filed (which I dragged and dropped from the list of field types present in dotCMS). Can you please share us how I can implement this validation?

Regards
