Jean told me some tradition in France. It is name's day which is original from Catholic church. Almost every name has it day. Such as St. Jean's day is on June 24th and St. paul and Pierre is on June 29. However there is no certain day for Saprina. So, my name belongs to all saints day on Nov 1st. However interesting to find something like that.

Next time coming to France, you better check about your name's day!
