Hours and Minutes Calculator

How to use the hours and minutes calculator?

Using our hours and minutes calculator is very simple. You just need to enter the two times between which you want to calculate the difference. You can do this in 12-hour (am/pm) or 24-hour format. Once you enter the data, the calculator will instantly show you the difference in hours and minutes.

How to calculate the difference in hours and minutes between 2 moments in time.

Calculating the difference between two moments in time is a common task that may be necessary in various situations, such as planning activities, tracking work time, or simply to know how much time has passed between two events. Below, we explain how to do it in both time formats.

In 24-hour format

To calculate the difference in 24-hour format, follow these steps:

1. Enter the start time and end time in 24-hour format (for example, 14:00 for 2:00 PM).
2. If the end time is less than the start time, add 24 to the end time (this covers cases where the end time is the next day).
3. Subtract the start time from the end time. If the difference in minutes is negative, adjust by subtracting one hour and adding 60 minutes.
4. The result will be the difference in hours and minutes.

For example, to calculate the difference between 22:30 and 01:15 the next day:

• 22:30 to 01:15 becomes 22:30 to 25:15 (adding 24 hours to 01:15).
• The difference is 25:15 - 22:30 = 2 hours and 45 minutes.

In 12-hour format (am/pm)

To calculate the difference in 12-hour format, follow these steps:

1. Enter the start time and end time in 12-hour format, clearly indicating if it is AM or PM.
2. Convert both times to 24-hour format to simplify the calculation (for example, 2:00 PM becomes 14:00).
3. If the end time is less than the start time, add 24 to the end time (this covers cases where the end time is the next day).
4. Subtract the start time from the end time. If the difference in minutes is negative, adjust by subtracting one hour and adding 60 minutes.
5. The result will be the difference in hours and minutes.

For example, to calculate the difference between 10:30 PM and 01:15 AM the next day:

• 10:30 PM becomes 22:30 and 01:15 AM becomes 01:15.
• 01:15 the next day becomes 25:15 (adding 24 hours to 01:15).
• The difference is 25:15 - 22:30 = 2 hours and 45 minutes.

Common applications of calculating hours and minutes

• Daily activity planning
• Tracking work hours
• Organizing events and meetings
• Monitoring study or training time
• Project management
• Calculating travel time

What do am and pm mean?

AM and PM are abbreviations used in the 12-hour format to distinguish between morning and afternoon. AM stands for "Ante Meridiem" in Latin, which translates to "before midday," and is used for hours from midnight to noon (12:00 AM to 11:59 AM). PM stands for "Post Meridiem," which translates to "after midday," and is used for hours from noon to midnight (12:00 PM to 11:59 PM).
