Question 1

Which calendars and countries does the API cover?

Accepted Answer

Both the Czech and Slovak name-day calendars for every day of the year, plus Czech public holidays — state holidays (státní svátky), other holidays, and significant days (významné dny). Each date returns the CZ and SK names separately.

Question 2

How do I look up a specific date or name?

Accepted Answer

Use GET /today for the current day, GET /date/{day}.{month} (e.g. /date/28.10) for any date, or search the other way with GET /search?name=Anna to find when a given name is celebrated.

Question 3

Are Easter and other movable holidays included?

Accepted Answer

Yes. GET /holidays (or /holidays/{year}) returns all fixed-date state and significant days with their exact day and month, plus movable holidays such as Good Friday and Easter Monday, flagged as "movable".
