I'm a dad and I think personally that having a "father's day" is not needed.
Being a dad/father and having your kids love you and call you daddy should be enough.
Society makes holidays so they can find a way to get you to give them your money by buying things you don't need.
If you are going to celebrate holidays perhaps it would be better if you make up your own hi days and set the dates yourself to be orignal.
Perhaps celebrate Christmas in June as an example
Or hide candy on your day of Halloween at night and give your kids flash lights to find them like they would on Easter.
Just my two cents.
