It sounds fine if you want to celebrate it, but honestly I have zero remembrance of my confirmation date.
I don’t remember my first communion date either, and of course being a baby when baptized I have no memory of my baptism date although that is recorded on my baptismal certificate somewhere.
I think these dates may be more memorable or important to converts who have thought long and hard about making a choice to join the Church, than to us Catholic kids for whom the sacraments were something we all did en masse on the schedule prescribed by our parish and Catholic school. I remember First Communion and Confirmation very well, but unfortunately the memories are more about things like adult nuns and parents fussing over my First Communion dress and how we walked in line and our kneeling posture, and us kids wondering what the Host would taste like, than about the joy of receiving Jesus Christ. I guess I was not one of the litle child saints.
As for Confirmation, I don’t think my confirmation prep was particularly adequate and a lot of the things I read about on here, like the bishop specially meeting with each young person being confirmed, or someone asking why I chose a particular saint, just didn’t happen. There were so many kids being confirmed back in my day that the Bishop would have needed a week to speak with every one of them personally. I did get a nice leather-bound encyclopedia of saints from my parents as a Confirmation gift, which I read and enjoyed and still have.
