Time Duration कैलकुलेटर — मुफ़्त ऑनलाइन टूल और फॉर्मूला
Decimal work-hour conversion model computing elapsed shift time, break deductions, and fractional billing increments.
फॉर्मूला और गणना की विधि
Calculates elapsed duration between start and end timestamps (12-hour AM/PM or 24-hour clock). When shifts cross midnight (end time earlier than start time), 24 hours (1,440 minutes) is added to the interval before deducting break minutes. The net minutes are then divided by 60 to produce decimal hours for timesheet and billing calculations.

Commercial Payroll Timesheet Calculation
An employee clocks in at 8:45 AM and clocks out at 5:15 PM, taking a 45-minute unpaid lunch break:
Sexagesimal Time vs. Decimal Payroll Accounting
Time is traditionally measured in the ancient Sumerian sexagesimal (base-60) numerical system (60 seconds per minute, 60 minutes per hour). However, enterprise ERP and payroll engines (such as ADP, QuickBooks, and SAP) operate in decimal (base-10) notation.
A common error is confusing 30 minutes with 0.3 hours. In reality, 30 minutes equals 0.50 decimal hours, and 15 minutes equals 0.25 hours. Using automated conversion eliminates payroll discrepancies and compliance audit liabilities.
Time Duration कैलकुलेटर से जुड़े अक्सर पूछे जाने वाले प्रश्न
How do I convert hours and minutes to decimal hours for payroll?
Divide the minute portion by 60 and add it to the hours. For example: 8 hours and 15 minutes = 8 + (15 ÷ 60) = 8.25 decimal hours.
Does this calculator handle shifts that cross midnight?
Yes. If the end time is numerically earlier than the start time (e.g., 10:00 PM to 6:00 AM), the calculator automatically detects an overnight shift across midnight and computes the continuous 8-hour elapsed duration.
What happens if I take multiple breaks during the day?
Simply add up the total minutes of all breaks taken (e.g., two 15-minute breaks and one 30-minute lunch = 60 minutes total) and enter the sum in the Break field.
Can I use 24-hour military time?
Yes. The calculator supports both standard 12-hour AM/PM formats and 24-hour military notation seamlessly.
