Calculating total hours worked from clock-in and clock-out times, including unpaid breaks, is a common task for hourly employees, freelancers, and small business owners managing payroll. This time card calculator computes the total hours worked across one or more shifts, automatically subtracting break time to give you the net working hours. It's useful for verifying paychecks, tracking billable hours for freelance work, or managing employee timesheets without manual subtraction errors that can easily occur with time arithmetic. Simply enter your start and end times along with any breaks to get an accurate total of hours worked.
