How to calculate time duration between two times:
Calculating the duration between two times involves the following simple steps:
- Identify start and end times:
Clearly note your start and end points (dates and times). For example, start: 9:30 AM and end: 2:15 PM. - Convert to 24-hour format (optional):
For convenience, convert times into a 24-hour format.- Example: 9:30 AM → 09:30, 2:15 PM → 14:15.
- Subtract start time from end time:
Subtract the hours and minutes separately. If the end minutes are less than start minutes, borrow an hour (60 minutes) from the hour’s column.- Example:
- Hours: 14 hours – 9 hours = 5 hours
- Minutes: 15 minutes – 30 minutes → borrow 1 hour (60 mins), (15+60) – 30 = 45 minutes. After borrowing, hours become 4 hours.
- Final result: 4 hours and 45 minutes.
- Example:
- Adjust for different dates:
If the end time is on a different day, first calculate full days between the dates, then follow the above steps to calculate hours and minutes separately.
Example:
- Start: March 1, 10:00 PM
- End: March 2, 6:30 AM
- Duration: 8 hours and 30 minutes.

How to calculate time duration between two dates and times:
To manually calculate the duration between two dates and times:
- Note the start and end dates and times: Clearly write down the exact start and end date-time combinations.
- Calculate days first: Count the full days between the dates, excluding the start and end dates.
- Calculate hours and minutes: For partial days, subtract the start time from the end time. Adjust the calculation if borrowing from hours is needed (if end minutes are less than start minutes).
- Combine results: Add days, hours, and minutes for the total duration.
