Guide

How to use the Hours Calculator

1Select your 'Start Time' using the time picker.
2Select your 'End Time'. If the end time is earlier than the start time, the calculator assumes the shift ends on the next day.
3Enter any 'Break Deduction' in minutes (e.g., 30 for a half-hour lunch).
4Click 'Calculate Hours' to see the exact time worked.
5Review the results in both HH:MM format and decimal format (useful for billing).

Applications

Common Use Cases

Payroll Entry: Converting hours worked into decimal format for payroll software.

Project Tracking: Measuring the precise time spent on a specific client task.

Shift Planning: Calculating shift lengths across midnight boundaries.

Self-Employment: Keeping an accurate log of billable hours for invoicing.

The Maths Behind the Calculation

Total Minutes = (End Minutes - Start Minutes) - Break Minutes

We convert both times into minutes from the start of the day, find the difference, subtract the break deduction, and then convert back into hours and minutes.
