In many countries people celebrate name days. In the Czech Republic, each day corresponds to one or more names and people celebrate their name days and they get gifts (just like they do on birthdays).
For some reason, there are Czech names that are not listed in the name day calendar. And oddly enough, men named Petr have TWO name days: one on February 22 and one on June 29 – together with Pavel (Paul).
