Days accrued, days left and their value under Spanish employment law.
Spanish law (Estatuto de los Trabajadores) guarantees at least 30 calendar days of holiday a year. If you’ve worked less than a year, you’re entitled to the pro rata share: about 2.5 days per month worked.
The legal minimum is 30 calendar days; many collective agreements express it as 22 or 23 working days, which is almost the same.
