Hours Calculator
Calculate exact hours and minutes between two times. Ideal for work schedules, payroll calculations, shift tracking, and timecards.
How to Calculate Work Hours Step-by-Step
Calculating total work hours for timecards or payroll is simple:
- Select Time Format: Choose 12-hour (AM/PM) or 24-hour (military time).
- Enter Start & End Times: Enter your shift start time (e.g. 08:30 AM) and end time (e.g. 05:00 PM).
- View Breakdown: Click "Calculate Hours" to view your exact hours, minutes, decimal hours, and 8-hour workday fractions.
Top Summary & Direct Answer
Direct Answer: An Hours Calculator computes the exact time difference (in hours, minutes, decimal hours, and 8-hour workday units) between a start time and an end time. It supports 12-hour AM/PM format and 24-hour military time, automatically handling overnight shifts crossing midnight.
- Overnight Handling: Seamlessly calculates shifts spanning midnight (e.g. 10 PM to 6 AM = 8 hours).
- Decimal Conversion: Automatically converts minutes to decimals (e.g. 7h 30m = 7.50 hours).
- Workday Metrics: Computes standard 8-hour workday equivalents for payroll.
Designed for hourly employees, freelancers, HR payroll managers, shift workers, and project managers to track work hours, compute timecard totals, calculate overtime, and bill clients accurately.
Understanding Hourly Wages vs. Salaried Employment
According to the U.S. Department of Labor (FLSA Guidelines), hourly employees must be compensated for every hour worked, including 1.5x overtime rates for hours exceeding 40 hours per workweek.

Frequently Asked Questions About Hours Calculation
How does the hours calculator handle overnight shifts crossing midnight?
Direct Answer:
Our calculator automatically detects when the end time is earlier than the start time (e.g. 10:00 PM to 6:00 AM) and adds 24 hours to compute the correct 8-hour shift duration without negative results.
How do I convert hours and minutes into decimal hours for payroll?
Direct Answer:
Divide the total minutes by 60 and add to the total hours. For example, 7 hours and 45 minutes equals 7 + (45/60) = 7.75 decimal hours.
What is the difference between 12-hour (AM/PM) and 24-hour military time?
Direct Answer:
12-hour time uses AM (morning) and PM (afternoon/evening) suffixes (e.g. 8:30 PM), while 24-hour military time runs continuously from 00:00 to 23:59 (e.g. 20:30) to eliminate AM/PM ambiguity.
How do I calculate work hours for payroll calculations?
Direct Answer:
Enter your clock-in time as the start time and your clock-out time as the end time. Convert the total time to decimal hours and multiply by your hourly wage rate.
