Frequently Asked Questions

How can I calculate my hours?

The most accurate method is using this digital Hours Calculator. Simply input your 'Clock In' and 'Clock Out' times. The tool automatically accounts for AM/PM cycles and date changes (overnight shifts) to provide your exact shift duration without manual math errors.

How to calculate total hours between two times?

To manually calculate duration, convert both start and end times to a 24-hour format (00:00 to 23:59). Subtract the start time from the end time. If the minutes of the end time are smaller than the start time, borrow an hour. Our tool automates this process instantly.

What is the formula to find hours?

The computational formula calculates the difference in milliseconds: (EndTime - StartTime) / 3,600,000. This converts the timestamp difference directly into decimal hours, which can then be formatted into a user-friendly "Hours and Minutes" display.

How do I add my work hours together?

Calculate the duration of each shift individually first. Convert the minute portion of each shift into decimal hours (Minutes / 60). Sum the total decimals to get your pay period total. Alternatively, sum hours and minutes separately, carrying over every 60 minutes into an additional hour.

How many hours is 40 hours a week?

40 hours represents the standard full-time workweek in the United States and many other nations. It typically equates to five 8-hour workdays. Exceeding this threshold usually qualifies an employee for overtime pay under standard labor laws.
