The topic of working time in August 2025 requires particular attention from employers, HR specialists, and managers responsible for scheduling work. This month includes one public holiday – August 15th – which affects the total number of working hours. According to the Labour Code, each public holiday falling on a weekday (excluding Sundays) reduces the monthly working time.
How to Calculate Working Time in August 2025
In accordance with Article 130 §1–2 of the Polish Labour Code, working time is calculated as follows:
- Multiply 40 hours by the number of full weeks in the month.
- Add 8 hours for any additional working days outside full weeks.
- Subtract 8 hours for each public holiday falling on a weekday.
In August 2025, the calendar looks as follows:
- 21 working days,
- 5 weekends (Saturdays and Sundays),
- One public holiday: Friday, August 15th – Assumption of the Blessed Virgin Mary.
Step-by-step calculation:
- 4 full weeks × 40 hours = 160 hours,
- 1 additional working day = 8 hours,
- Total: 168 hours,
- Subtract 8 hours for the public holiday,
- ✅ Final working time in August 2025: 160 hours.
Impact of August 15th Holiday on Work Planning
The public holiday on August 15th falls on a Friday, creating a long weekend. For employers using shift work or flexible schedules, it is advisable to plan ahead for time off, employee absences, or potential overtime. Incorrect scheduling may lead to violations of working time regulations and potential scrutiny from the National Labour Inspectorate (PIP).
It’s important to note that the 8-hour reduction applies to all employees, regardless of the type of employment contract or work schedule – as long as August 15th falls on a day they would otherwise be scheduled to work. Employers using time tracking systems such as Time Harmony can more easily manage the impact of public holidays on working time settlements.
Working Time in August 2025 – Summary
The final working time in August 2025 is 160 hours for employees working in a standard five-day, one-shift workweek. This reduction is due to the public holiday on Friday, August 15th. Employers must calculate working hours correctly in order to comply with Polish labour law, especially when preparing schedules and work time records.
