Hours Calculator
What Is an Hours Calculator?
An Hours Calculator is a free tool that calculates the exact number of hours and minutes between two specific times — a start time and an end time. It handles AM/PM formats, crosses midnight automatically, supports decimal hour output for payroll calculations, and can add up multiple time blocks across an entire workday or workweek. Our free DaniProTools Hours Calculator is the fastest way to calculate work hours, track billable time, verify payroll, compute overtime, or measure any time duration without manual arithmetic.
Manual time calculation is error-prone — especially when dealing with time formats, crossing midnight, summing multiple time blocks, or converting between hours:minutes and decimal hours. Our Hours Calculator eliminates all of these headaches instantly and for free.
How to Use the Hours Calculator
- Enter your start time (e.g. 9:00 AM)
- Enter your end time (e.g. 5:30 PM)
- Optionally enter a break duration to subtract (e.g. 30 minutes lunch break)
- Click 'Calculate Hours'
- See the total hours and minutes worked, and the decimal hour equivalent for payroll

Hours to Decimal Conversion — For Payroll and Invoicing
Many payroll systems and invoicing tools require time in decimal format (e.g. 7.5 hours) rather than hours and minutes (7 hours 30 minutes). Here is how to convert:
Decimal Hours = Hours + (Minutes ÷ 60)

Weekly Timesheet Calculator — Adding Up Multiple Days
For freelancers, remote workers, and employees tracking weekly hours, our calculator can handle daily totals. Simply calculate each day's hours and use the sum below as a reference:
- Monday: 7 hours 30 min = 7.5 hrs
- Tuesday: 8 hours 0 min = 8.0 hrs
- Wednesday: 7 hours 45 min = 7.75 hrs
- Thursday: 8 hours 30 min = 8.5 hrs
- Friday: 7 hours 0 min = 7.0 hrs
- Total weekly hours = 38.75 hrs (add each day's decimal total together)
Overtime Calculation — Working Hours Beyond Standard
In Pakistan and most countries, standard working hours are 8 hours per day or 48 hours per week. Hours beyond this threshold qualify as overtime and are typically compensated at 1.5x the regular hourly rate (time-and-a-half) or 2x for work on public holidays.
Overtime Pay = (Regular hourly rate × 1.5) × Overtime hours worked
Q: Is the Hours Calculator free?
A: Yes, 100% free. Calculate time durations, work hours, and payroll time with no account required.
Q: Does the Hours Calculator work for night shifts that cross midnight?
A: Yes. Simply enter your start time (e.g. 10:00 PM) and your end time (e.g. 6:00 AM) and the tool automatically calculates the correct duration across midnight — 8 hours in this example.
Q: How do I convert 7 hours 45 minutes to decimal for payroll?
A: Divide the minutes by 60 and add to the hours: 7 + (45 ÷ 60) = 7 + 0.75 = 7.75 decimal hours.
Q: What is the standard work week in Pakistan?
A: Under Pakistan's Factories Act and Employment Ordinance, the standard working week is 48 hours — 8 hours per day, 6 days per week. Many private sector companies operate on a 40-hour, 5-day week. Hours beyond the legal maximum must be compensated as overtime.
