How the Hours Calculator Works

Formula or calculation logic

Total hours = Σ(end time − start time − unpaid breaks)

Step-by-Step Practical Example

Follow a realistic set of inputs from start to finish to understand what the result means.

Example 1: A standard work week.

  1. 1.Enter the inputs: Monday–Friday, each day 09:00 to 17:00.
  2. 2.Apply the logic: Apply the formula above to the listed inputs for "A standard work week".
  3. 3.Read the result: Each day = 8h. Total = 40h 0m across 5 days. Daily average = 8h.

Example 2: Days with different shift lengths.

  1. 1.Enter the inputs: Mon 08:00–16:30, Tue 09:00–15:00, Wed 08:30–17:00.
  2. 2.Substitute the inputs: Place the listed inputs into the formula above for "Days with different shift lengths".
  3. 3.Read the result: 8h 30m + 6h 0m + 8h 30m = 23h 0m total. Daily average ≈ 7h 40m.

Example 3: Part-time hours over four days.

  1. 1.Enter the inputs: Mon 10:00–14:00, Wed 10:00–13:30, Thu 12:00–16:00, Sat 09:00–12:00.
  2. 2.Verify the calculation: Work through the formula above for "Part-time hours over four days", then compare the displayed result.
  3. 3.Read the result: 4h + 3h 30m + 4h + 3h = 14h 30m total. Daily average ≈ 3h 38m.

Frequently Asked Questions

How do I calculate hours worked?

Subtract the start time from the end time. For example, 9:00 AM to 5:30 PM = 8.5 hours. Don't forget to subtract any unpaid break time.

How do I convert minutes to decimal hours?

Divide minutes by 60. Example: 1 hour 45 minutes = 1 + (45 ÷ 60) = 1.75 hours. This is the format typically used for payroll calculations.

How many hours is a full-time job?

In the US, full-time is typically 40 hours/week (8 hours/day). Some sectors define full-time as 35 or 37.5 hours. Overtime usually applies above 40 hours.

Does this calculator handle overnight shifts?

No — each row calculates the hours between a start and end time on the same day. For a shift that crosses midnight, split it into two rows (e.g. start–24:00 and 00:00–end).

What does the calculator show me?

It shows the hours for each day you enter, the total across all days, and the daily average. It does not calculate pay, overtime, or break deductions.
