How to calculate the number of working days?
To calculate the number of working days in any month, you need to consider the following factors:
The total number of days per month: in September 30.
Number of weekends: it’s Saturdays and Sundays. In September 2025 there are 8 of them.
Number of holidays: in peacetime, the holidays that fall on weekdays are weekends. However, during martial law, this rule does not apply.
Calculation formula: total number of days – number of weekends = number of working days.
30 – 8 = 22.
September 2025 will be a standard working month without additional weekends. If you are planning a vacation or important cases, keep in mind that working hours will last 22 days. Effective planning will help you achieve your goals and keep your work and rest.
