Name days across calendars and borders
Name days across calendars and borders: this guide has a section for each day plus a page per name joins the official Estonian, Finnish, Latvian…
This launch guide maps the topic, the source base and the practical questions. Check the linked official authority before acting on a rule, deadline, price or safety requirement.
What this guide covers
This guide has a section for each day plus a page per name joins the official Estonian, Finnish, Latvian, Lithuanian, Swedish-Finnish, Orthodox and Russian calendars without claiming they share one authority. Each name page shows language, variants, next date and calendar source; date pages explain celebration customs and expose API-friendly structured data. Historical calendar editions are kept separate so changed dates remain auditable.
How to use it
Use Name days across calendars and borders as a structured learning path: begin with the vocabulary, follow the evidence map, and keep the uncertainty labels attached to claims as you compare sources.
The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.
Search vocabulary in four languages
Terminology changes across borders. These are example phrases people use for the same subject in Estonian, Finnish, Russian and English; they are included as a practical vocabulary aid, not as hidden keywords.
| Language | Example phrase |
|---|---|
| Estonian | millal on Taavi nimepäev |
| Finnish | nimipäivä tänään |
| Russian | именины сегодня по православному календарю |
| English | Baltic name day calendar |
Evidence and provenance
The evidence map below records the primary, official or openly licensed material chosen for this guide. It is deliberately visible so a reader can tell the difference between a rule published by an authority, a measured dataset and an editorial explanation.
