How this service works
Taiwan business day check from the ROC government office calendar (via the TaiwanCalendar project): whether a date is a business day, with weekends and public holidays counted as non-business days, and optionally the business-day count across a range. Covers about 2017 onward; dates outside coverage return a clear not-found error.
Output
Returns a JSON object with the queried date's business-day status (is_business_day boolean), holiday status (is_holiday boolean), day of week, and a human-readable description of the day. If a range_end date is provided, also returns the count of business days across the range and a list of holidays within it. Includes attribution, data sources, disclaimer, and a verified_on timestamp.
Example use cases
Contract deadline validation for Taiwan
“I need to know if March 31, 2025 is actually a business day in Taiwan — we have a contract deadline on that date and need to confirm it's not a public holiday or weekend.”
Business-day count for payment settlement
“How many business days are there in Taiwan between April 1, 2025 and April 30, 2025? I need this to calculate payment settlement windows for our Taiwanese supplier.”
Holiday check for scheduling automation
“Is October 10, 2025 a working day in Taiwan? I'm building a scheduler that needs to skip Taiwanese public holidays and I want to verify this date.”
Technical details
Endpoint
GEThttps://tariffmonkee.com/paid/tw-business-day-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need Taiwan (ROC) business-day logic that accounts for official government public holidays, not just weekday/weekend filtering. It is ideal for automating payment settlement, scheduling, or deadline calculations that must respect Taiwan's official holiday calendar. Prefer it over generic weekday calculators whenever Taiwan-specific holiday accuracy is required.
Side effects
- Date outside coverage (pre-2017 or future dates beyond calendar data): returns a clear not-found error
- Invalid date format (not YYYY-MM-DD): request will fail with a validation error
- range_end spans more than 2 calendar years: rejected with an error
- Network or payment failure: HTTP 402 if payment not processed
