In this Page the word name means - first name.

I just wanted to add that no special calendars were ever needed to know the Name Days. Each calendar printed in Latvian had to have the names, otherwise it would be considered as completely useless and nobody would buy it. It seems that the tradition to celebrate the Name Days origins from the Christian religions that honors the Saints and has for them the special days of commemoration.

The Name Days were celebrated by Lutherans (Latvians and Germans), as well as by Catholics, but their name thesauruses were different. The Orthodox believers celebrated Angel's days that were practically the same as the Name Days because the name of the Guardian Angel or the Saint coincides with the name of a person and can be find in the calendar of the names.

In this Page two sets of the names are published that were used by Latvian Catholic and Latvian Orthodox communities. The source I found for the Orthodox names seems to be a fragment of the original Russian name thesaurus used by Orthodox believers of Russian ethnicity. The original Russian name thesaurus contains many names for a day - for some days even 40 names, and many names are repeated several times, because there were several saints of the same first name. The source for the Catholic names was printed in the time of the WW2 and may be contains some extra names of German origin. It contained additionally some information on those saints and their deeds whose names were included in the Catholic name thesaurus.

It should be clearly stated that most of the names of both thesauruses published here were never used in practice. They contain only proposals. The clergy of both confessions, however, insisted that the real names should be chosen from these thesauruses.

The names for Lutheran community can be found in analogous page.

The sources:

Please, take into account that the Angel days of orthodox are listed by the Julian calendar that was in force in the Russia Empire at the time of the publishing of the source.
