Hours Calculator (Time Between Two Clocks)

How many hours is that shift, really?

Timesheets, freelance invoices and internship logs all come down to one question: how many hours did I actually work? The hours calculator turns two clock times and a break into an exact hours-and-minutes figure, then multiplies by days per week so you can fill out a timesheet or quote a weekly total without mental arithmetic.

The formula

Times are read on a 24-hour clock internally; "9 to 5" with a 30-minute unpaid lunch is 480 − 30 = 450 minutes = 7h 30m per day.

Worked example

You clock in at 09:00 and out at 17:00 (480 minutes) with a 30-minute unpaid break. Paid shift = 450 minutes = 7h 30m. Over 5 days that is 37.5 × 5 = 37h 30m/week — just under the 40-hour full-time line, which matters for overtime eligibility.

Reference: common shifts (no break)

Use it for

• Timesheets: convert each day to minutes, sum, submit.
• Freelance invoicing: bill by exact worked time, not rounded guesses.
• Overtime awareness: see when weekly total crosses 40h.

Frequently asked questions

Common mistakes tracking work hours

The biggest mistake is rounding to the nearest hour and losing money — ten minutes a day is almost an hour a week, or ~47 hours a year of free work. Another is forgetting to subtract only the unpaid break; paid breaks are already worked time. People also confuse a 12-hour shift with 12 paid hours when an hour was unpaid lunch. And when filling timesheets, entering "8" for a day that was actually 7h 50m undercounts by 50 minutes weekly.

Scenario: catching unpaid overtime creeping in

A salaried non-exempt employee logs 8h 30m daily, five days, plus a 20-minute unpaid break each day — 8h 10m × 5 = 40h 50m. That half hour over 40 means the employer likely owes overtime for it. Tracking exact minutes with this tool surfaces the threshold crossing that rounding would hide, protecting pay.

Taxes, benefits and the number you actually keep

Hours worked drive gross pay, but also accrue benefits like PTO (often earned per hour) and may trigger overtime taxes differently. Precise hour logs also support unemployment or disability claims later, where exact dates and hours matter.

Honest time tracking and "time theft"

Both sides benefit from accurate logs. Employees who round down lose pay; those who round up risk disciplinary action for "time theft," a real legal concept in some states. Exact minute tracking with this tool keeps everyone fair and defensible if a dispute arises.

Remote and flexible schedules

With remote work, clock-in/out blur. Tracking actual focused hours — not seat time — helps freelancers bill honestly and helps employers measure output. Enter your real start, end and breaks; the minutes figure is what matters for trust and invoicing.

Timesheet software versus manual logs

Many employers use apps that round or auto-pause; comparing their total to your manual exact minutes (from this tool) catches discrepancies. Keep your own log weekly so a month-end surprise is fresh, not a faint memory. The export-free, private nature of this calculator makes it a safe personal checkbook.

Billable hours for freelancers

Freelancers live by exact hours. If you bill $60/hour and work 6h 45m, that is 6.75 × 60 = $405, not a rounded $420 or shorted $360. Tracking to the minute and multiplying protects both your income and your client's trust, and the weekly total helps you forecast monthly revenue.

Hourly pitfalls in the gig economy

Gig and on-demand work rarely pays for the time between tasks — a driver "working" eight hours may only bill five of active trips. Track both clock time and billable time with this tool to see your true effective rate, which is often far below the headline. That clarity helps you decide which platforms and shifts actually pay, and protects you from burning a full day for part-day money.
