How to prevent from overlapping the Dates with unique field values in Salesforce?

I have a requirement,in a object i have to restrict for  creating records on below case:
Suppose I have created a records and on custom field(Test_code__c) I have put value:”ABC”,and start date–>29/11/2019
End date:->29/12/2019

So in next records if I tried to create the record with same value ‘ABC’,the Start date and End should not be overlaped.
