How to use the hours calculator?
By simply modifying the start and end times, and clicking calculate, our tool will efficiently provide the number of hours you've worked in hours, minutes, and decimals. This is particularly useful for your time card calculations, saving you time and effort.
For example, begin by adding the start time to 9:30 and the end time to 17:00 then click calculate. The calculator will provide the hours between times in decimal hours and hours, minutes.
The start time is when you start recording your timing, and the end time is when the calculation ends. If the calculation goes beyond the current date, use the following calculator. The converter is specifically made to calculate the time between two dates. The calculator will practically update based on the local format of your browser.
How do you convert digital time to decimal time?
If you have worked 8:30, or 8 hours and 30 minutes, then the equivalent decimal time is 8.50. To convert from minutes to decimal hours, divide the minutes by 60 (the number of minutes in an hour). 30/60 =0.5 hours.
In this case, 8 + 0.5 = 8.5 decimal hours.

How to convert from decimal time to hours and minutes?
Let’s say you’ve worked 9.25 decimal hours. To convert the amount to hours and minutes, multiply the decimal part by the amount of minutes in an hour (60 minutes). So, 0.25 x 60 = 15 minutes.
This results in 9 hours and 15 minutes.
If your work hours span multiple days, this calculator can accurately report the time duration between two dates, helping you avoid manual calculations.
How to use the time between dates calculator?
When your shift spans across days, the manual calculation can be daunting. Our calculator simplifies this process. Just define the start and end dates and times, and the calculator does the rest. With a single press of the calculate button, the system presents a summary and the result in hours and minutes plus hours decimal, giving you the confidence that your calculation is accurate.
Tip: Also, see the days calculator to review the number of days between a specific number of days, with the possibility of adding and subtracting hours and a working days calculator.
Calculate work hours with lunch
If you use the clock calculator, specify the start to end of your workday, and want to add a specific number of minutes of break, then this calculator provides the required answers. Tip: if you want to calculate the weekly total, use this calculator that allows to add your entries for each day of the week, and provides the total daily and weekly instantly.
The tool accurately calculates the entire hours worked and deducts the break time. Once you click Calculate, you can be sure that you will have a precise breakdown of your time in hh:mm and hours decimal, providing you with a secure understanding of your work hours. One common use of this calculator is how many hours is 8am to 5pm with lunch? Just change the timings in the form above and you get your answer instantly.
For example, this work hours calculator will save you a lot of time when you want to calculate work hours for payroll exactly, excluding the lunch break. When your workday starts at 8:30 AM and ends at 5:00 PM, and you have a 30-minute break, then you know that your workday will be 8 hours.
How to calculate hours worked manually?
If you want to do the calculation of the hours worked manually, then follow these steps:
1. Convert the start and end times to 24 hours
In 24-hour format, AM times remain as they are, yet you add 12 hours for PM times.
8:30 AM to 5 PM becomes 8:30 and 17:00.
2. Convert minutes to decimal
To convert 8:30 into decimal hours, you must divide the minutes by 60.
30/60 = 0.5, so 8:30 becomes 8.50
5 PM or 17:00 is already in decimal form.
3. Subtract the end time from the start time
This is very simple and straightforward. We have 17 as the end time and 8.5 as the start time; subtracting the start and end times will give us 8.5 hours.
17-8.5 = 8.5 hours
4. Deduce breaks
For this example, the worker took a 30-minute break, which is 0.5 hours decimal.
Now, we will deduce the break time from the total time worked, and we will have the total time worked excluding breaks.
8.5- 0.5 = 8 hours worked.
Therefore, from 8:30 AM to 4:50 PM, we have 8 hours, excluding 30 minutes lunch break.
Tip: When you need to sum up some times, or add few hours to a particular time, check out the time calculator.

What is the difference between a 12-hour clock vs. 24-hour clock?
The main difference between a 12-hour and a 24-hour clock is how time is displayed and measured. Let’s see the details for both of them:
12-hour clock
A 12-hour clock is the most commonly used clock, dividing the time into two 12-hour periods AM/PM as following:
At a 12-hour clock, the same hour can be used two times, depending on the AM/PM designation. For example:
24-hour clock
A 24-hour clock, also known as military time, is used in many professional and technical fields, such as aviation, navigation, and computing. It divides the day into 24 equal periods, starting from 00:00 (midnight) to 23:59 (11:59 PM).
In a 24-hour clock, each hour has a unique representation, eliminating the need for AM/PM designations. For example:
How do you convert between 12-hour and 24-hour clocks?
Converting from a 12-hour clock to a 24-hour clock follows these rules:

How many hours is part-time?
The definition of part-time hours can vary depending on the country, state, or organization. However, the Fair Labor Standards Act (FLSA) does not define part-time hours in the United States. Generally, part-time hours are less than 35-40 hours per week. Here are some common part-time hour ranges:

How to calculate overtime?
Overtime is typically paid at 1.5 times the employee's regular hourly rate. Here's how to calculate overtime:
Example:
For an employee with a regular hourly rate of $20/hour and who has worked 45 total hours, we consider 40 hours the overtime threshold. This means that his overtime hours will be 45 - 40 = 5 hours. Since the overtime hours are paid at a 1.5 pay rate, the overtime pay rate will be 20/hour x 1.5 = $30/hour, and the overtime pay for the week will be 5 hours x $30/hour = $150.
If we need to calculate weekly pay, we must sum up regular and overtime pay:
