Holiday API comparisons

Most holiday APIs answer "is this a public holiday?". Bankday answers "will this payment settle, and when?". Here's how it compares, fairly.

Bankday vs Calendarific

Calendarific is a solid choice for public holidays and observances across 230+ countries. Bankday is built for a different question: whether money moves on a given day, with payment-rail calendars and business-day math built in.

Bankday vs HolidayAPI

HolidayAPI offers deep historical holiday data and state/province coverage on annual plans. Bankday focuses on settlement calendars and business-day arithmetic with monthly, usage-based pricing.

Bankday vs Nager.Date

Nager.Date is a free, open-source public holiday service, and a great fit for hobby projects and simple holiday lookups. Bankday adds what production finance systems need on top: settlement calendars, business-day math and support.

Bankday vs python-holidays

python-holidays is an excellent MIT-licensed library, and Bankday's country and exchange calendars are built on it. The difference is operational: a library has to be kept current in every service, in one language, while Bankday is one HTTP call from any stack.
