How does this name day calculator work?

Type your name and we search our database of real cultural name day calendars from 8 countries: USA, Greece, Poland, Italy, Spain, Germany, Sweden, and France. We show your name day in every country where it appears, including variant forms of your name in other languages (e.g., John shows results for Jean in France, Giovanni in Italy).

Why does my name show different dates in different countries?

Each country maintains its own name day calendar based on local traditions, saints, and cultural history. The same name (or its local variant) may be associated with different saints or feast days in different countries. For example, Maria's primary name day is August 15th in most countries (Assumption of Mary), but Poland celebrates it on many additional dates throughout the year.

What if my name isn't found?

Our database covers nearly 6,000 names across 8 countries. If your exact name isn't found, we use fuzzy matching to find the closest variant. Name days are most common for names with European Christian origins — names from other cultural traditions may not appear in these calendars.

What does 'via [name]' mean in the results?

When you see a result labeled 'as Jean' or 'as Giovanni', it means your name wasn't found directly in that country's calendar, but a related variant was. John, Jean, Giovanni, Juan, Jan, and Hans are all forms of the same name — we connect them so you see your name day across all cultures.

How accurate is the Name Day Calculator?

Results are as accurate as the underlying name-day calendars and sources used for each country or tradition. Some regions have multiple accepted calendars (religious vs. civil, old vs. revised), which can produce different dates for the same name. If a country has conflicting listings, the calculator may show the most commonly referenced date or provide alternatives when available.

Name day vs birthday — what's the difference?

A birthday marks the anniversary of a person’s birth date and is personal to the individual. A name day is tied to a calendar date associated with a given name, often based on saints’ days or traditional name lists. Many people celebrate both, but name days are shared by everyone with the same name in that calendar.

Is the Name Day Calculator free?

Yes, the Name Day Calculator is free to use for standard lookups. You can search names and view results without paying or creating an account. Some optional features or integrations, if offered, may have separate terms.

About the Name Day Calculator

Name days are a real part of the calendar in many places, tied to saints’ days, local traditions, and the way families celebrate. With ProCalc.ai’s Name Day Calculator, you can quickly check when a name is honored across the USA, Greece, Poland, Italy, Spain, Germany, Sweden, and France, along with the name’s meaning and the customs that go with it. It’s especially useful if you’re planning a cross-cultural celebration, like an expat family keeping Greek name day traditions while living in the U.S., or a wedding planner trying to avoid scheduling an Italian reception on the bride’s name day. You simply type a name into the Name Day Calculator, and you get the relevant calendar date(s) by country plus cultural notes you can actually use. For example, if you’re sending a card to your Polish coworker named Katarzyna, you can confirm her name day date before you mail it, then add a line that matches the tradition instead of guessing. Free, instant, and based on real cultural calendars—not made-up dates.

What is a name day?

A name day is a cultural tradition in many European and Latin American countries where each calendar day is associated with one or more given names, typically based on Catholic or Orthodox saint feast days. People celebrate their name day much like a birthday — with greetings, small gifts, or gatherings.

What Is the Name Day Calculator?

The Name Day Calculator finds the feast day or saint's day associated with a given first name across multiple traditions — Catholic, Orthodox, Polish, Greek, Czech, Hungarian, Slovak, German, Italian, and Spanish calendars. Enter a name, get the date (or dates) it's celebrated and the patron saint or origin story.

How to Use This Calculator

Type a name in the search box. The calculator returns a list of traditions where the name is celebrated, with each date and a short note on the saint or namesake. You can also browse by date — useful for finding all names celebrated on a particular day, like September 15 or November 11.

Common Use Cases

Greeting card timing: In Greece, Poland, and much of Eastern Europe, the name day is often celebrated more than the birthday — knowing the date matters for sending wishes on time.
Genealogy research: Old church records often note baptismal names tied to nearby saint days, which can help narrow birth date estimates.
Baby naming: Parents picking a name with cultural roots often check the name day calendar to match a meaningful date.
Travel etiquette: Visiting someone in Poland on their imieniny is a thoughtful gesture; the name day chart tells you when to bring the flowers.

Understanding the Results

Some names appear on multiple dates across traditions — Maria, John, and Anna can have a half-dozen feast days between Catholic and Orthodox calendars. The calculator shows all of them and labels the source tradition. If a name is rare or modern, it may not have a traditional feast day; the lookup will note that and suggest a closely related saint name.

Industry Standards and Tips

The Roman Catholic General Roman Calendar is the canonical reference for Western feast days, while the Orthodox calendar uses both Old Style (Julian) and New Style (Gregorian) dates depending on the local church. Polish name days follow the imieninowy kalendarz, which differs slightly from the Vatican list. Greek name day customs are tied to the saint of the local parish church, not just the calendar.

Pair this with the Birthday Calculator to find names celebrated on the same date as a birth, or the Birthstone Calculator for matched cultural traditions.

What Is a Name Day?

A name day is a tradition celebrated across Europe, Latin America, and many other cultures. Each day of the year is associated with one or more given names, typically tied to Catholic or Orthodox saint feast days. In many countries — especially Greece, Poland, Hungary, Sweden, and France — name days are celebrated as enthusiastically as birthdays.

How This Calculator Works

Type any name and instantly see its celebration dates across 8 countries (USA, Greece, Poland, Italy, Spain, Germany, Sweden, France). Our AI generates a rich profile for every name — meaning, origin, saint associations, famous bearers, and related name variants across languages.

Cross-Language Name Matching

Names evolve across borders. John becomes Jean in France, Giovanni in Italy, Juan in Spain, and Ivan in Russia. Our calculator automatically finds these connections through AI-generated related names, showing you name days for all variants in every country.

Fuzzy Matching

Misspelled a name? We will find the closest match. Type "jonn" and we will show you results for Jon. For unusual names, we generate a complete profile using AI — meaning, origin, and cultural context for any name on earth.

Name Days Around the World

Name day traditions vary significantly by country. In Greece, name days (onomastiki eorti) are often celebrated more than birthdays — friends visit without invitation. In Poland, imieniny involve hosting gatherings with cake and drinks. Sweden maintains one of the world's most carefully curated name day calendars, officially managed by the Swedish Academy.

Data Sources

Our name day database covers 8,638 entries across 8 countries, sourced from nameday.abalin.net (MIT License) and supplemented by Behind the Name and UNESCO cultural heritage records. AI-generated name profiles are powered by Google Gemini and cached for instant access.

How the Name Day Lookup Works

This calculator queries a database of 8,638 name day entries across 8 country calendars. When you type a name, the system follows a three-step resolution process.

Step 1 — Exact match. Your name is normalized (diacritics removed, lowercased) and matched against the calendar database. If "Mary" exists in the US calendar for August 15, that result returns instantly.

Step 2 — Fuzzy matching. If no exact match is found, PostgreSQL trigram similarity (pg_trgm) scores your input against all known names. A score above 0.5 triggers an automatic redirect — "Jonn" becomes "Jon." Lower scores offer a suggestion without redirecting.

Step 3 — Cross-language resolution. The system checks the name profile for related variants. "John" connects to Jean (France), Giovanni (Italy), Juan (Spain), Jan (Poland), and Hans (Germany). Each variant is queried separately, and results are merged with a "via" label showing the connection.

All lookups are deterministic — no AI is involved in the date calculation. The calendar data comes from nameday.abalin.net (MIT License), cross-referenced with Behind the Name for variant forms.
