In the Czech Republic, each day of the year, except national holidays, corresponds to a personal name.
In the past, parents were not allowed to choose just any name for a child.
The original list was the Roman Catholic calendar of saints, but many changes were made to reflect the present-day usage of names.
The name day is commonly of less importance than birthdays to Czech people.
The celebration can be held together with friends or co-workers of the same name and in this way, it can grow in size and "importance".
