❓ Frequently Asked Questions
How do I calculate the time between two times?
Use the Time Difference tab. Enter your start time and end time using the HH:MM:SS fields. Select AM/PM or 24-hour format. Results appear instantly as you type, showing total duration, hours, minutes, seconds, and decimal hours.
How do I calculate work hours with break deduction?
Switch to the Work Time tab. Enter your shift start time, end time, and break duration in minutes. The calculator automatically deducts the break and shows actual work hours, decimal hours, overtime, and earnings if you enter an hourly rate.
Can I add multiple time durations together?
Yes! Go to the Add Time tab. Click "Add Another Time Entry" to add as many rows as you need. Enter hours, minutes, and seconds for each entry. The calculator sums all entries and displays the total duration.
What is decimal hours and how is it used?
Decimal hours converts time into a single decimal number. For example, 8 hours 30 minutes = 8.5 decimal hours. This format is commonly used in payroll systems and spreadsheets, making it easy to multiply by an hourly rate (8.5 × $15 = $127.50).
How does the weekly timesheet calculator work?
The Timesheet tab lets you enter start and end times for each day of the week along with break durations. It calculates daily work hours, weekly total, average hours per day, and total weekly pay if you provide an hourly rate.
Can I calculate time differences across multiple days?

Time Calculator Calculate Hours, Minutes & Time Differences Instantly
The Time Calculator from My Calcly helps you calculate the exact difference between two times in hours and minutes. Whether you’re tracking work shifts, billable hours, study sessions, or travel duration, this tool gives you a clear and instant answer.
It removes the confusion of manual subtraction and reduces small mistakes that can affect payroll, invoices, or schedules.
Quick Answer
To calculate time difference:
Total Duration = End Time − Start Time
The calculator automatically converts hours and minutes, handles time crossing noon or midnight (if dates are included), and shows the total duration clearly in hours and minutes.
Enter your start time and end time, and the result appears instantly.
What This Time Calculator Does
This tool calculates:
- Time difference between two clock times
- Total hours and minutes worked
- Duration between events
- Time intervals for shifts or sessions
It works as a duration of time calculator, useful for both personal and professional use.
What You Need to Enter
Start Time
Example: 9:00 AM
End Time
Example: 5:00 PM
Optional Date (if available)
Helpful if the time crosses midnight.
What the Result Means
The result shows:
- Total hours
- Total minutes
- Combined duration (for example: 8 hours 30 minutes)
If your time spans different days, the calculator adjusts accordingly when dates are included.
How the Time Calculation Works
The calculator performs simple time subtraction:
- Convert both times into minutes
- Subtract start time from end time
- Convert the result back into hours and minutes
Key relationships:
- 1 hour = 60 minutes
- 1 minute = 60 seconds
Example:
Start: 2:30 PM
End: 4:15 PM
Convert to minutes:
- 2:30 PM = 150 minutes past noon
- 4:15 PM = 255 minutes past noon
Difference:
255 − 150 = 105 minutes
105 minutes = 1 hour 45 minutes
Practical Examples
Work Shift
Start: 9:00 AM
End: 5:00 PM
Total = 8 hours
Study Session
Start: 2:30 PM
End: 4:15 PM
Total = 1 hour 45 minutes
Travel Duration
Start: 6:00 AM
End: 11:30 AM
Total = 5 hours 30 minutes
Workout
Start: 7:10 PM
End: 8:05 PM
Total = 55 minutes
Expert Insights for Accurate Time Tracking
Break Deductions Matter for Payroll
If you’re calculating work hours:
Start: 8:55 AM
End: 6:20 PM
Total = 9 hours 25 minutes
But if you had a 1-hour unpaid break, your payable hours are:
9 hours 25 minutes − 1 hour = 8 hours 25 minutes
Always subtract unpaid breaks before calculating wages.
Crossing Midnight Can Cause Errors
Example:
Start: 10:00 PM
End: 2:00 AM
Manual subtraction can be confusing.
Correct duration:
4 hours
If your shift spans midnight, including the date ensures accuracy.
Decimal Hours vs Hours & Minutes
Some billing systems require decimal hours.
Example:
1 hour 30 minutes = 1.5 hours
45 minutes = 0.75 hours
If you invoice clients, confirm whether they require decimal format or standard time format.
Time Zone Differences for Remote Work
If working with international clients, always confirm:
- Which time zone is being used
- Whether daylight saving adjustments apply
This tool calculates duration between entered times but does not automatically adjust time zones unless manually selected.
Common Mistakes to Avoid
- Forgetting to subtract break time
- Confusing AM and PM
- Not accounting for midnight crossover
- Rounding minutes incorrectly
- Mixing 24-hour and 12-hour formats
Small errors can add up over weeks of payroll or billing.
When This Calculator Is Enough
This tool works well for:
- Tracking freelance billable hours
- Calculating daily work shifts
- Measuring study sessions
- Estimating travel time
- Planning productivity sessions
For official payroll systems or legal timekeeping, always confirm calculations using employer-approved software.
Strong Disclaimer
This calculator is designed to provide an estimate based on your selected start and end times using standard time calculation methods. Actual payroll amounts, overtime compensation, and official attendance records may vary depending on employer policies, labor laws, rounding rules, break deductions, and time zone adjustments.
For payroll, legal employment matters, or contractual billing disputes, verify calculations with your employer, HR department, or a qualified professional.
