Overview
The Czech Namedays Calendar API lets you look up the Czech or Slovak nameday (svátek) associated with a given first name, or find whose nameday falls on a specific date. It is completely free with no authentication required and supports JSON responses. Responses are instant and lightweight, making it great for beginners.
Beginner Tip
No API key needed — call the endpoint directly. To get today's nameday, try https://api.abalin.net/today?country=cz. Supported country values are "cz" and "sk".
Available Data
