Finland has approximately 11 official public holidays annually. In addition to these, Christmas Eve and Midsummer's Eve are practically observed as working days off, although they are not officially recognized public holidays from a legislative perspective. A key concept for payroll and HR purposes is the working day public holiday (arkipyhä), which refers to a public holiday falling on a weekday – it directly impacts the number of billable and paid working days. Finland does not have a substitute day system, meaning that if a public holiday falls on a weekend, no compensatory day off is granted on a weekday.
How do working day public holidays affect the pay of monthly-salaried employees in Finland?
A monthly-salaried employee's pay does not generally change due to working day public holidays – they receive the same monthly salary regardless of how many arkipyhä fall within the month. The situation differs for hourly-paid employees: payment for working day public holidays is only made if agreed upon in the employment contract or collective bargaining agreement. Employers should verify the provisions regarding arkipyhä compensation in the applicable collective agreement, as these vary by industry.
Christmas Eve is a day off in many companies, but is it an official public holiday?
Christmas Eve (24.12.) is not an official public holiday under Finnish legislation, but in practice, almost all employers grant it as a day off. In many collective bargaining agreements, Christmas Eve is explicitly listed as a day off. In payroll processing, it should be treated as a non-working day, although its legal status differs from official public holidays.
What happens if a public holiday falls on a weekend – does the employee receive a compensatory day off?
No. Finland does not have a substitute day system, so a public holiday falling on a weekend does not automatically entitle the employee to a compensatory day off on a weekday. For example, if a public holiday falls on a Saturday, it does not increase weekday time off that week. This distinguishes Finland from many other European countries where substitute day practices are common.
When do Midsummer Day and All Saints' Day fall in 2026, and how do they appear in working day calculations?
In 2026, Midsummer Day falls on Saturday 20.6. and Midsummer's Eve on Friday 19.6. All Saints' Day falls on Saturday 31.10. Since Midsummer's Eve is a Friday, it effectively reduces the working days in that week. All Saints' Day, however, falls on a weekend, so it does not affect the number of working weekdays and no compensatory day off is granted.
How many working day public holidays does 2026 contain, and how should they be considered in workforce planning?
In 2026, most official public holidays fall on weekdays, making it a particularly demanding year for payroll purposes. For example, Easter brings Good Friday, Easter Sunday, and Easter Monday in succession, and both May Day and Ascension Day also fall on weekdays. In workforce planning, particular attention should be paid to the concentration of public holidays in spring, April–May, which significantly reduces the number of available working days. Staffing and leave planning should be completed well in advance to ensure smooth operations and service delivery.
