Where they differ
fincalapi covers a set of exchange and SIFMA bond calendars and makes them easy to use from spreadsheets. This API also covers the settlement system behind each major currency and every country’s public holidays, and it combines several calendars in one request.
The other difference is provenance. Each verified year here names the official notice it was checked against and keeps a dated, hashed copy of it, and a changes feed lists every date each release added, removed or modified.

Questions
Which should I use?
If you need one of the exchange calendars fincalapi covers, in a spreadsheet, either will do, and its worked examples are a quick start. If a payment or trade depends on more than one market, needs a settlement-currency calendar, or you need to show where a date came from, this API is built for that.
