Time & Work Calculation Guides

Learn how working time is calculated across shifts, breaks and time-card entries. These guides explain time arithmetic, decimal-hour conversion and practical methods for checking hours worked. They are useful when reviewing timesheets, comparing scheduled and actual hours, or understanding how unpaid breaks affect a daily or weekly total. You can also learn how to handle shifts that cross midnight, convert hours and minutes into decimal hours, and avoid common errors when adding several work periods together. These methods are useful for employees, managers, freelancers and anyone checking a time card before calculating a final total.
