Built for Real-World Scheduling

🏢

HR Scheduling

Automatically exclude public holidays when calculating leave balances, payroll cycles, and shift rosters across multiple countries.

📈

Trading Calendars

Skip non-trading days in financial models and backtests. Identify bank holidays that affect settlement and clearing windows.

📦

Logistics ETAs

Calculate accurate delivery estimates by skipping holidays in the origin, transit, and destination countries automatically.

⚙️

n8n Automation

Wire into n8n or Zapier workflows to gate time-sensitive actions — skip sending emails or reports on national holidays.

HolidayAPI & Nager.Date Alternative

Current-year data, future-year planning, and a production SLA — without the free-tier year lock or community-project reliability risk.

The HolidayAPI free-tier trap

HolidayAPI's free plan is intentionally limited to the previous calendar year only. Need to look up holidays for the current year or plan ahead for 2027 leave schedules? You must upgrade to a paid plan. For any scheduling or automation use case, this makes the free tier practically useless from day one.

The Nager.Date reliability risk

Nager.Date is a community-maintained open-source project — free to use but with no uptime SLA, no support contract, and no guarantee of continued availability. Teams that have built payroll systems or logistics pipelines on it have been caught out by unexpected downtime or deprecation. Fine for prototyping; not for production.

Frequently Asked Questions

Q: Which countries are supported?

A: 100+ countries via the open-source python-holidays (vacanza) library. This includes the US, UK, Germany, France, Japan, China, Australia, Canada, India, Brazil, and most of Europe, Asia, Latin America, and Africa. Use a valid ISO 3166-1 alpha-2 code (e.g. US, GB, DE).

Q: How far back and forward can I query?

A: You can query any year from 1900 up to 10 years in the future. Historical holidays are computed based on the rules that were in effect at the time, so results reflect actual historical observances rather than today's rules projected backwards.

Q: Are regional/state holidays included?

A: This endpoint returns national public holidays only. State-, province-, or region-specific observances (e.g. US state holidays, German Länder holidays) are not included in the default response. Contact us if you need subdivision-level holiday data.

Q: Can AI agents use this as a tool?

A: Yes. The endpoint takes two query parameters (country and year) and returns a structured JSON array — straightforward to define as a function tool for OpenAI, Claude, LangChain, or any agent framework. Ideal for scheduling agents that need to reason about working days across multiple countries.
