To complete the wage calculation, you must first choose the weekly working day. The reason for choosing this is that if you work 6 days, you work 7.5 hours a day. For 5 days, you should be working 9 hours a day. Legally, the weekly working time has been accepted as 45 hours. After making this selection, you can enter your annual, monthly, weekly, daily or hourly income and enter Enter and calculate the amount of your income in different units.
