22 business days
September 2026 has 30 calendar days in Spain. Of these, 22 are business days — Monday to Friday that are not national public holidays — while 8 are weekend days and 0 national public holiday dates fall on a weekday and are deducted.
No national public holiday falls on a weekday this month, so the weekend is the only thing removed from the calendar. If days observed only in part of the country, or only in particular sectors, are also excluded, the count falls to 19.

22 business days × 8 hours = 176 working hours in September 2026, before any leave, and assuming a standard 8-hour day (40-hour week). On a 7.5-hour day the total is 165 hours; on a 7-hour day, 154 hours. Weekends and the national public holidays listed above are not worked, so they add no hours.

Start with every date in September 2026, keep the Mondays to Fridays, then remove the dates marked “Yes” in the holiday table above. The number you get is the one shown at the top of this page: 22. Dates marked “Regional or sector-specific only” are observed in part of Spain or in certain industries, so they are listed for reference but not deducted.
