Step 1. Input the Start Time information in the respective fields.
1.1. Tap or click the drop-down arrow, and select the Month and Day. Next, type in the value for the Year.
Quick tip: Tap the “Today” option to select today as the Start Time automatically.
1.2. Enter the values for hours, minutes, and seconds in the respective fields. Note that the values you input must be integers equal to or higher than 0.
Quick tips: Tap or click the “Now” option to auto-fill current time values for hours, minutes, and seconds. If you choose the “Start a day” option, the values for H-M-S will be 12:00:00 AM. If you select the “Noon” option, the values for H-M-S will be 12:00:00 AM.
Step 2. Select “+Add” or “-Subtract”.
Step 3. Input the time duration you want to add to or subtract from the “Start Time.”
Note: The values you enter must be integers equal to or higher than 0.
Step 4. Press the “Calculate” button to see the results.
Step 5. Press the “Clear” button and repeat the above steps to calculate other time values.
While the Time Calculator makes these operations effortless, it’s also useful to understand how to perform these calculations manually. Below is one of the simple methods:
Step 1. It’s recommended to convert the time into a 24-hour format (before doing any calculation) to simplify the calculation and ensure its accuracy.
Step 2. Add or subtract the hours, minutes, and seconds separately: Be mindful of carryovers or borrowings.
For instance, if the result is beyond 60 minutes or 24 hours, convert the excess into hours or days. Or if the minutes you need to subtract are greater than the minutes in the start time, borrow 1 hour (60 minutes) and add it to the start time's minutes before performing the subtraction.
Example 1: To determine what time will it be in 43 minutes, you will need to add 43 minutes to the present time. Let’s say it’s currently 3:35 PM (15:35); adding 43 minutes to 15:35 will give you 16:18 (4:18 PM).
Example 2: To find out how long until 2:35 PM (14:35), you will need to subtract the current time from 14:35. If it’s 11:45 AM now, subtracting 11:45 from 14:35 would be 2 hours and 50 minutes. That means there’s 2 hours and 50 minutes left from now until 2:35 PM.
Step 1. Determine the starting date and time as well as time value you want to add to or subtract from it. Convert times into a 24-hour format if needed.
Step 2. Start with the Seconds: Add or subtract the seconds. Convert any overflow to minutes.
Step 3. Proceed to Minutes and Hours: Add or subtract minutes and hours, converting overflow as needed.
Step 4. Adjust the Date: Finally, add or subtract the days, adjusting the month and year if necessary.
For example, here’s how to find out what day 20 days from today is, assuming that the current date and time is 11:00 AM, August 2. By adding 20 days, 0 hours, and 0 minutes, the result will be 11:00 AM, August 22.
Multi-unit calculation: The ability to perform calculations involving various units of time, such as seconds, minutes, hours, days, and years, enabling you to calculate whatever period, regardless of its length or complexity.
Precision and reliable calculations: Ensure fast, accurate calculations even for calculations involving large amounts of time or complex time conversions.
Conversion capabilities: The option to convert time between different units provides flexibility for those who need results in varying time formats.
Quick and easy to use: Our intuitive and easy-to-use interface simplifies the process of entering and manipulating time values, assisting you to calculate the duration between two dates or times quicker than ever.

Time and date are fundamental concepts that have shaped human civilization since the dawn of our existence. Though highly abstract, time and date have set frameworks for humans to understand the world around us. Without the appearance of date and time concepts, it’s hard to imagine how we would have organized our lives and measured the passage of events.
The earliest methods of timekeeping were based on observing the natural world, such as the sun's movement across the sky. Sundials, for example, were used to tell time by the position of a shadow cast by a stick or obelisk. Other early timekeeping methods included water clocks and hourglasses, which measured the time by the movement of water (for a water clock) from one container to another or sand (for hourglasses) through a narrow neck.
In the 17th century, the pendulum clock—an invention from Christiaan Huygens—was a significant breakthrough in timekeeping. This device was far more accurate than earlier mechanical clocks and could be used to measure time to within a few seconds per day.
The 20th century saw the rise of more accurate timekeeping devices, like quartz, atomic, and GPS clocks. Quartz clocks boast an accuracy of a few seconds per year, whereas atomic clocks exhibit precision within a few seconds per billion years.
These days, the Global Positioning System (GPS) is one of the most modern timekeeping systems, using a network of satellites to synchronize clocks around the world. GPS clocks are accurate to within a few nanoseconds, making them the most precise timekeeping devices in existence.
American and European timekeeping systems differ in clock formats and time zone management. The United States primarily employs a 12-hour clock, dividing the day into two AM and PM periods, while most European countries utilize a 24-hour clock, expressing time in a continuous format from 00:00 to 23:59. For example, in the US, 09:00 AM means 9 o'clock in the morning, and 09:00 PM means 9 o'clock in the evening, but in Europe, 09:00 means 09 o'clock in the morning, and 21:00 means 09 o'clock in the evening.
Additionally, the United States has four main time zones, while Europe has a more complex network of time zones due to its geographical diversity. Understanding these differences is crucial for travelers and business professionals navigating between the two regions.
Time units are the standard means of measuring and expressing time intervals. They are used in various fields, including science, engineering, everyday life, and more. Here are the seven most commonly used time units, of which the second is the base unit:
Time units | Equals | Equals to seconds |
Second (s) | Base Unit | |
Minute (min) | 01 minute = 60 seconds | 60s |
Hour (hr) | 01 hour = 60 mins | 3,600s |
Day (d) | 01 day = 24 hrs 01 day = 1,440 mins | 86,400s |
Week (wk) | 01 week = 7 days 01 week = 168 hrs 01 week = 10,080 mins | 604,800s |
Month (mo) | 01 month has from 28 to 31 days 01 month ~ 4 weeks | From 2,419,200s to 2,678,400 |
Year (y) | 1 year has 365 or 366 days 1 year ~ 52 weeks | ~31,557,600 seconds |
The hour (hr) is also a basic unit of time. Similar to seconds and minutes, the number of hours in different periods varies depending on how long that period is. They increase as the length of the period increases, and vice versa. The following table displays the number of hours in some common time periods:
Time Period | Numbers of Hours |
01 Decade | It depends |
01 Year | 8,760 or 8,784 hours |
01 Month | From 672 hours to 744 hours |
01 Week | 168 hours |
01 Day | 24 hours |
01 Hour | 1 hour |
01 Minute | 0.01666666666 hours |
01 Second | 0.00027777777 hours |
