How do I calculate work hours with breaks?
Use the Duration Calculator tab. Enter your clock-in and clock-out times, then specify the total break duration in minutes. The calculator will automatically subtract break time from your total work hours.
Can I add time that goes beyond 24 hours?
Yes! The Time Arithmetic calculator can handle times that exceed 24 hours. For example, adding 20 hours to 8:00 PM will correctly show 4:00 PM the next day (or 28:00 in extended format).
How do I calculate time difference across midnight?
In the Time Difference calculator, check the "End time is next day" checkbox when your end time is after midnight. For example, from 10:00 PM to 2:00 AM (next day) would be 4 hours.
What time units can I convert between?
The Time Conversion calculator supports seconds, minutes, hours, days, weeks, months (30 days), and years (365 days). You can convert any unit to any other unit instantly.
How accurate is the earnings calculation?
The earnings calculation multiplies your work hours by the hourly rate you enter. It's accurate for regular hourly calculations but doesn't account for overtime rates, taxes, or other deductions. Always verify with your actual payroll system.
Can I use this for project time tracking?
Absolutely! The Time Difference and Duration calculators are perfect for tracking project time, calculating billable hours, or measuring time spent on tasks. You can calculate multiple time periods and add them together.
How do I subtract more time than I have?
If you subtract more time than available (e.g., subtract 2 hours from 1 hour), the result will show a negative time. This can be useful for calculating time deficits or overages in scheduling.
What format should I use for time input?
Enter hours (0-23 for 24-hour format), minutes (0-59), and seconds (0-59) in separate fields. The Duration Calculator also accepts standard time picker format (HH:MM) for convenience.
Is this calculator suitable for scientific calculations?
Yes, the calculator provides precise calculations suitable for scientific and engineering applications. The time conversion feature is particularly useful for converting between different time units in scientific contexts.
Can I calculate time zones with this calculator?
This calculator performs time arithmetic and conversions but doesn't handle time zone conversions. For time zone calculations, you would need to manually account for the time difference between zones.
