Calculate the last working day in a given month for any Spanish municipality. The tool starts at month-end and walks backward past weekends and published holidays.
Not a legal-deadline calculator. For a binding administrative, court, tax or employment deadline, verify the applicable rule and official gazette.
Rules
Select municipality, year and month inside 2024–2026. Coverage is limited to published calendars so the answer cannot silently invent future holidays.
The engine takes the last calendar day of that month and steps backward until it lands on a Monday–Friday without a published holiday for that place.
If month-end is already a working day, that date is returned. If it falls on a Sunday or a local feast, you get the previous working day instead.
Use the municipality link in the result to inspect which holidays affected that month.
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.

Questions

Month-end can coincide with a regional or local holiday that differs by territory.
The walk continues backward through the month until it finds a working day, still inside published coverage.
Not necessarily. Payroll or convenio calendars may treat some weekdays differently. This tool uses published public holidays only.
Use the next/previous mode from the last day of the prior month, or open the other calculator modes from the hub.
