Calculate start time, end time, unpaid breaks, overnight shifts, and time rounding in one simple tool.
Grownu’s free time clock calculator helps you calculate daily work hours from a start time, end time, and breaks. It is useful for one shift, one workday, quick timesheet checks, and reviewing hours before payroll. Add unpaid breaks, choose a rounding rule, and see the result without building formulas in Excel or Google Sheets.
The calculator is designed for real-world shift work. If the end time is earlier than the start time, the tool treats the shift as ending on the next day, which makes it easier to calculate overnight shifts. You can also turn on an overnight window, such as 10:00 PM to 6:00 AM, to see how much of the shift falls inside that range.
Use the rounding settings when your company records time in fixed increments, such as 5, 10, 15, 30, or 60 minutes. You can round to the nearest interval, round down, or round up. After calculating, copy the result, download a CSV file, or share the calculation with a manager, payroll team, or coworker.
This daily calculator is a practical spreadsheet alternative for individual employees, small teams, supervisors, HR teams, and operations managers who need a fast way to check work-hour totals. For longer periods, use the weekly timesheet calculator or monthly timesheet calculator.
When manual time tracking becomes too slow, Grownu helps companies move from one-off calculations to automated clock-ins, approvals, schedules, reports, and exports. Start with this calculator, then use the time tracking ROI calculator to estimate how much time and money your company could save by replacing spreadsheets.
