Move a starting date forward or backward by N working days in Spain. The starting date itself is not counted; only later (or earlier) Mondays–Fridays without published holidays advance the counter.
Not a legal-deadline calculator. For a binding administrative, court, tax or employment deadline, verify the applicable rule and official gazette.
Rules
Select the municipality whose published calendar should apply. Regional and local holidays change the landing date even when the national calendar is the same.
Choose the starting date, whether to add or subtract, and how many working days (1–2,000) to move — always within the published 2024–2026 range.
The engine walks day by day, ignoring weekends and published holidays, until N working days have been consumed. The start date never counts toward N.
If the operation would land outside the published calendars, the interface asks you to reduce N rather than inventing uncovered dates.
Use cases
Method
Here a working day is Monday–Friday that is not a published national, regional or local public holiday for the chosen Spanish municipality. Saturdays and Sundays are always excluded. Half-days, company calendars, collective agreements and court or tax rules can define a different day — this page does not apply those special regimes.
