A time calculator adds or subtracts hours and minutes. Example: a meeting starts at 9:30 AM and lasts 2 hours 45 minutes — it ends at 12:15 PM. Or: how many hours between 8:00 AM and 5:30 PM? Answer: 9 hours 30 minutes. Use it for work hours, travel time, and scheduling.

🤔 How Does This Work?
Our Time Calculator handles three types of time calculations:
Between two times: converts both times to minutes since midnight, finds the difference, and converts back to hours and minutes. Handles overnight shifts by adding 1440 minutes (24 hours).
Add time: converts start time to minutes, adds the specified hours and minutes, then wraps around 24 hours if needed.
Subtract time: converts start time to minutes, subtracts the specified hours and minutes, then handles negative results by wrapping around 24 hours.
Results are shown in both hours:minutes format and decimal hours (useful for payroll and billing).

❓ FAQ
How do I calculate hours worked?▼
Enter your start time and end time in the 'Between two times' mode. For example, 9:00 AM to 5:30 PM = 8 hours 30 minutes. If you worked a night shift that crosses midnight, check the 'overnight' box.
How do I add hours and minutes to a time?▼
Select 'Add time to a start time', enter your starting time, then enter the hours and minutes to add. For example: 10:45 AM + 3 hours 20 minutes = 2:05 PM.
How many hours is a standard working day?▼
A standard working day is typically 8 hours (e.g. 9 AM to 5 PM). With a 30-minute lunch break, your actual working time would be 7.5 hours. Use our calculator to find exact hours for any schedule.
How do I convert hours to decimal for payroll?▼
Divide minutes by 60 to get decimal hours. Example: 8 hours 45 minutes = 8 + (45/60) = 8.75 hours. At a rate of 500 rupees per hour, 8.75 hours = 4,375 rupees. Our calculator shows both formats.
What happens if end time is before start time?▼
If your end time is earlier than your start time (like a night shift from 10 PM to 6 AM), check the 'overnight' box and the calculator will correctly add 24 hours to calculate across midnight.
