How this service works
Spanish business-day calculator: count business days between dates or add N business days, using Spain's national public holidays.
Output
Returns a JSON object with: the computed number of business days (dias_habiles), the start date (desde), the resolved end date (hasta), and an array of Spanish national public holidays that fall within the date range (festivos_en_el_rango), each with its date and name. May also include a note (nota) for edge cases.
Example use cases
Invoice payment deadline calculation
“I need to know what date falls exactly 30 business days after January 10, 2025 in Spain — factoring in all Spanish national holidays — so I can set the correct payment due date on a contract.”
Project milestone scheduling
“How many working days are there between April 7, 2025 and June 30, 2025 in Spain? I need to plan a project timeline and exclude all Spanish public holidays.”
Legal notice countdown
“We need to send a legal notice that requires a 15 business-day response window under Spanish law. If we send it on February 3, 2025, what is the deadline date, counting only Spanish working days?”
Technical details
Endpoint
POSThttps://api.vextorium.com/dias-habiles-pago?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need business-day calculations specifically governed by Spain's national public holiday calendar — for example, computing payment deadlines, legal notice periods, or project milestones under Spanish commercial law. Prefer it over generic date-diff utilities when Spanish holiday exclusion is required and over region-specific tools when national-level holidays suffice.
Side effects
- Missing required 'desde' field returns a validation error
- Providing both 'hasta' and 'sumar_dias' simultaneously may cause ambiguous or erroneous results
- Invalid date format (non-YYYY-MM-DD) causes a parse error
- End date earlier than start date may return zero or negative business day count
- Requesting very large date ranges may produce unexpected results or timeouts
- Regional Spanish holidays (autonomous community level) are not included, only national ones
