Shift End Time Calculator

Find your shift end time by entering your start time and shift length. Works for all shift lengths including overnight. Fast and accurate.

Your shift end time is simply your start time plus your shift length. This calculator computes that instantly and displays your result in both 12-hour and 24-hour format. For overnight shifts, it shows the correct next-day time with a "+1 day" label so there's no ambiguity.

This is the same core function as the main clock-out calculator, framed around finding "when does my shift end" rather than "what time do I clock out." Some people think of their schedule as shift start and duration; others think of shift start and end. This tool works either way.

How employers communicate shift times:

Most schedules are posted in one of these formats: - Start time + duration: "8-hour shift starting at 7:00 AM" - Start and end time: "7:00 AM – 3:00 PM" - Military time: "0700–1500"

If you have a start time and duration but not an end time, this calculator is your tool. If you have a start and end time but want to know the duration, use the "hours between two times" calculator instead.

How to use the Shift End Time Calculator

  1. Enter your start time: Type or pick the time you started (or will start) your shift. Both 12-hour (AM/PM) and 24-hour formats are accepted.
  2. Pick your shift length: Select your paid shift length — 4, 6, 8, 10, 12 hours, or any custom value. Half-hour options are available.
  3. Add your unpaid break: Choose any unpaid break that extends your time at work. Common options are 15, 30, 45, or 60 minutes.
  4. Read your clock-out time: The result panel shows when you'll clock out, in both 12-hour and 24-hour formats. Overnight shifts display a +1 day badge.

Frequently Asked Questions

When does a shift starting at 2:30 PM for 8 hours end?

Your shift ends at 10:30 PM. Add 8 hours to 2:30 PM: 2:30 + 8:00 = 10:30 PM.

What is the end time of a 12-hour shift starting at 11:00 PM?

Your shift ends at 11:00 AM (+1 day). Starting at 11 PM and adding 12 hours crosses midnight — you finish the following morning at 11:00 AM.

How do I calculate shift end time without a calculator?

Add the shift hours to your start time. If the result goes over 12 (12-hour format) or 24 (24-hour format), subtract that number. For example: 9 PM + 10 hours = 19 PM → subtract 12 → 7 AM (+1 day).

Is shift end time the same as clock-out time?

Yes — in most contexts these are the same. Your clock-out time is when your shift ends and you stop working. The exception would be if mandatory post-shift duties (like cleaning or closing) extend beyond your scheduled end.

What if I'm asked to stay late — does that change my shift end time?

Yes. Add however many extra hours you're staying to your scheduled end time to get your new clock-out time. If staying late pushes you over overtime thresholds, you're entitled to overtime pay.

Overtime thresholds reference the U.S. Fair Labor Standards Act (FLSA, 40 hrs/week at 1.5x) plus state daily overtime rules (e.g., California Labor Code §510: 8h/day OT, 12h/day double-time).
