Our hours calculator offers two calculation modes: calculating hours between two times on the same day, or calculating hours between two dates with specific times. Here's how to use each:
The calculator automatically handles overnight shifts (when end time is earlier than start time, indicating the next day). Results display in hours and minutes format (e.g., "8 hours 30 minutes").
This mode is perfect for calculating hours worked across multiple days, such as project durations or weekly work hours. The calculator accounts for full 24-hour days between your selected dates.
The calculator displays results in a clear format showing total hours and minutes. For example, if you work from 9:00 AM to 5:30 PM, the result will show "8 hours 30 minutes". This format makes it easy to convert to decimal hours for payroll (8.5 hours) or to verify against your timesheet records.
Scenario: Sarah works a standard office shift from 9:00 AM to 5:30 PM with a 30-minute lunch break.
Input:
Calculation: The calculator computes the difference: 5:30 PM - 9:00 AM = 8 hours 30 minutes
Result: 8 hours 30 minutes (Note: Subtract 30 minutes manually for lunch break = 8 hours worked)
Scenario: Mark is billing a client for a design project. He worked from 10:15 AM to 3:45 PM on Monday, then 2:00 PM to 6:30 PM on Tuesday.
Day 1 Input:
Day 1 Result: 5 hours 30 minutes
Day 2 Input:
Day 2 Result: 4 hours 30 minutes
Total Billable Hours: 10 hours (5.5 + 4.5 hours)
Scenario: Maria works the night shift from 11:00 PM to 7:00 AM the next day.
Input:
Calculation: The calculator handles the overnight shift by calculating from 11:00 PM Monday to 7:00 AM Tuesday.
Result: 8 hours 0 minutes
Note: For overnight shifts, always use the "Hours Between Two Dates" calculator to ensure accurate results.
Use this free hours worked calculator: enter your start time and end time (with AM/PM), then click Calculate. You get total time worked in hours and minutes instantly. For the same day use "Hours Between Two Times"; for multiple days use "Hours Between Two Dates." For break deduction, overtime, and weekly totals, use our Work Hours Calculator.
Enter your start time and end time in the calculator above. The tool automatically calculates total hours and minutes worked. For example, 8:30 AM to 5:30 PM is 9 hours. For weekly totals and break time deduction, use our Work Hours Calculator.
An hours calculator gives time duration between any two times. A work hours calculator adds break time deduction, overtime, and weekly totals. Use our Hours Calculator for simple duration; use our Work Hours Calculator for work-specific features.
Enter your start time and end time, select AM or PM for each, and click Calculate. For the same day use "Hours Between Two Times"; for multiple days use "Hours Between Two Dates." Results show hours and minutes.
The calculator shows total time between your start and end times (including any break). To exclude break time, subtract it from the result. For example, 9:00 AM to 5:30 PM (8.5 hours) minus a 30-minute lunch = 8 hours worked. For automatic break deduction, use our Work Hours Calculator.

Results are precise to the minute. It handles overnight shifts, multi-day periods, and midnight crossings correctly. Reliable for payroll, billing, and time tracking.
When calculating hours between two times on the same day, if your end time appears earlier than your start time (e.g., start: 11:00 PM, end: 2:00 AM), the calculator assumes you mean the next day and adds 24 hours automatically. However, for clarity and accuracy with overnight shifts, we recommend using the "Hours Between Two Dates" calculator and explicitly selecting both dates.
Our calculator works with the times you enter as-is and doesn't automatically convert between time zones. If you're calculating hours across different time zones, you'll need to convert both times to the same time zone first, or use a dedicated time zone converter. For time zone conversions, consider using our time converter tool.
The calculator doesn't automatically account for daylight saving time (DST) changes. If your calculation spans a DST transition date, the result may be off by one hour. For precise calculations during DST periods, consider the specific dates and whether DST is in effect for your location.
Always double-check your input times before calculating. Common mistakes include selecting the wrong AM/PM period, entering times in the wrong format, or selecting incorrect dates. The calculator will show an error message if the end time is before the start time in the date calculator mode, helping you catch input errors.
The calculator shows total elapsed time between your entered times, which includes breaks. To calculate actual work hours excluding breaks, calculate the total time first, then manually subtract break durations. For example, if you work 9:00 AM to 5:30 PM (8.5 hours) with a 1-hour lunch break, your actual work hours would be 7.5 hours.
