Validate a specific date and month

Kindly could you please help me with date validation.

I would like to set up an event with registration form, where user can pick only one date, 14 February. the years doesnt matter. Condition of the query is: Only14 February in different years.
1.What type of validation rule should i set?
2.Which validation Rules should i insert according my query?

Thank you in advance!!!

I would use a drop-down or radio button field for this instead, giving the registrants the option of
Feb 14 2016
Feb 14 2017
etc.
-or-
Set the field title to something like "Please choose the year of your first Valentines Day (Feb 14) together", and set a drop down to contain the possible years they can choose from.

If you need an actual date field however, this won't work quite as nicely

I think this can be done with validation, using the funcCall method as listed here: posabsolute.github.io/jQuery-Validation-.../#funccallmethodname . You will need a Javascript function written to test the dates.
This answer doesn't answer your question but it will get you pointed in the right direction

Is there someone reading this post that is a javascript wiz and can help with the code?
