About ShiftHours
ShiftHours is a simple online tool for one everyday question: how much time did I work?
What it does
The calculator estimates net shift time from clock-in and clock-out values. It can subtract unpaid breaks, account for shifts that cross midnight, display decimal hours, and total multiple daily shifts for a week.
How it works
The calculations run in your browser. The tool converts clock times into minutes, calculates the duration, and subtracts the unpaid break you enter. Weekly totals use the same basic method for each filled row.
Our approach to accuracy
We aim to make the arithmetic transparent and easy to check. The calculator is not an official time clock, payroll service, or legal adviser. It does not determine overtime eligibility, tax, paid-break rules, daylight-saving adjustments, or employer-specific rounding.
