8-Hour Shift Calculator

Calculate your clock-out time for any 8-hour shift. Enter your start time and see exactly when you get off, including overtime and break deductions.

The 8-hour workday is the foundation of modern labor law. Since Henry Ford famously standardized the 8-hour workday in 1926, it's been the benchmark for full-time employment across nearly every industry. Whether you're working a standard 9-to-5, a rotating 7-3 hospital shift, or a midshift in retail, knowing your exact clock-out time matters.

This calculator is pre-filled for 8-hour shifts. Enter your start time and it instantly calculates when you'll clock out — accounting for any unpaid breaks that reduce your paid hours but don't change your departure time.

Common 8-hour shift schedules: - First shift: 7:00 AM – 3:00 PM - Day shift: 9:00 AM – 5:00 PM - Second shift: 3:00 PM – 11:00 PM - Swing shift: varies by industry

Break rules for 8-hour shifts

Federal law doesn't require employers to provide meal breaks, but most states do. A typical 8-hour shift in manufacturing or healthcare includes a 30-minute unpaid lunch. That means you clock out at 8 hours from your start time, but you're only paid for 7.5 hours. Some employers offer paid 15-minute rest breaks at the start or end, which don't reduce paid time.

Frequently Asked Questions

If I start at 8 AM and work 8 hours, what time do I get off?

With no break, you clock out at 4:00 PM. With a 30-minute unpaid lunch, you clock out at 4:30 PM — your paid hours stay at 8 but you're at work for 8.5 hours total.

Does a 15-minute break count against my 8 hours?

Usually not. Federal law and most state laws require employers to pay for short rest breaks (under 20 minutes). A 15-minute break is typically paid, so it doesn't reduce your total paid hours.

Am I entitled to overtime if I work more than 8 hours in a day?

It depends on your state. California, Colorado, Nevada, and a few others require daily overtime after 8 hours. Most states follow federal FLSA, which only requires overtime after 40 hours in a workweek.

What's a typical 8-hour shift schedule in healthcare?

Hospitals commonly run 7-3, 3-11, and 11-7 shifts (day, evening, night). Each is exactly 8 hours. Nursing staff on 8-hour shifts often get 1-2 paid 15-minute breaks and an unpaid 30-minute meal break.

How many paid hours is an 8-hour shift with a 30-minute lunch?

8 paid hours. The 30-minute unpaid lunch extends your time at work to 8.5 hours but doesn't reduce your pay — your shift length is the paid portion.
