Calculate working days between two dates

Count how many working days fall in an inclusive date range for a Spanish municipality. Both the start and the end count when they are working days; Saturdays, Sundays and published public holidays are excluded.

Not a legal-deadline calculator. For a binding administrative, court, tax or employment deadline, verify the applicable rule and official gazette.

Count working days between two dates

    Choose a municipality from the list so regional and available local holidays can be applied.

    Rules

    How it works

    Pick a municipality (INE code). That selects the national calendar, the regional calendar of its autonomous community, and the local dates currently published for that place.

    Enter a start and an end date inside the published 2024–2026 window. The count is inclusive: if either boundary is a Monday–Friday without a published holiday, it adds one working day.

    The breakdown shows calendar days, weekend days, weekday holidays and the resulting working days, so you can see what was subtracted — not only a bare total.

    If local coverage for that municipality is still incomplete, only the dates already published are used. The result links back to the municipality calendar so you can check sources and status.

    Use cases

    When to use this tool

    • Estimate how many business days sit between two project milestones, invoice periods or delivery windows in Spain.
    • Compare the same range in two municipalities when regional or local holidays differ (for example Madrid vs. a Catalan town with a published local feast).
    • Prepare a quick check before reading a statutory deadline rule — then verify that rule separately, because inclusive calendar arithmetic is not the same as every legal “día hábil” regime.

    Method

    Working-day definition on festivos.io

    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.

    Questions

    FAQ for this mode

    Are the start and end dates included?

    Yes. In this mode each boundary counts if it is a working day for the selected municipality.

    Does the tool use UK or US bank holidays?

    No. It uses Spanish public holidays for the municipality: national, regional and local dates currently published on festivos.io.

    What if my end date is before the start?

    The form blocks inverted ranges. Choose an end date on or after the start.

    Can I go past 2026?

    Not yet. Results outside the published 2024–2026 calendars are blocked so the tool cannot return a plausible but incomplete answer.

    Is this the same as a legal deadline count?

    No. Courts, tax offices and employment rules can exclude different days or shift the starting day. Use this for general calendar arithmetic, then confirm the applicable norm.
