What you are looking at
Nager.Date is a free open API that aggregates public holiday calendars for around one hundred and ten countries. The tool reads this year's calendar and the list of upcoming holidays.
A YES verdict means today is a public holiday and lists the name and local name. A NO verdict tells you the date of the next public holiday and how many days away it is.
The list covers national holidays. Some countries also have regional holidays that vary by state or province, which this tool does not show. The proof card shows the answer stamped by the live AffixIO API with an ML-DSA-65 signature.
Questions
Do I need an API key?
No. The calendar data is free and open. The signed verdict uses a throwaway demo key that the page requests from the live AffixIO API on its own.
Does it show regional holidays?
No. The list covers national holidays. Some countries also have regional holidays that vary by state or province, which this tool does not show.
What does the proof card show?
The answer stamped by the live AffixIO API: a proof id, an audit id, the policy version, and an ML-DSA-65 signature over the payload digest.
