there is lot of previous posts which deal with your problem or at least they can outline the solution, so please try to search for them.
The solution then will depend on the desired functionality, whether you would like to validate just a date pattern, or something specific which has to be validated on server side.
Feel free to ask more in case you have additional problems when implementing your choosen solution.
