THE QUICK ANSWER
How do you calculate hours worked?
To calculate hours worked, subtract clock-in from clock-out and deduct only unpaid breaks. Add the daily totals for your workweek. For example, 9:00 AM to 5:30 PM with a 30-minute unpaid lunch is 8 hours worked.
This free time card calculator shows hours:minutes and decimal hours together. Use the default weekly view, switch to a biweekly time card, or enter just one day for a daily calculation. Printing and CSV exports are available without an account.
Overnight shifts are handled clearly
A clock-out time earlier than clock-in automatically ends on the following day. A +1 day label makes that assumption visible. For a full 24-hour shift, select “End on the next day” in that day’s options.

Exact minutes first. Rounding only when you choose it.
By default, this time clock calculator keeps the exact minute values you enter. The optional quarter-hour rule rounds clock-in and clock-out separately: minutes 1–7 round down and 8–14 round up. It never changes your break durations. A neutral rounding policy must not systematically undercount work.
Weekly overtime and estimated gross pay
The default estimate treats work above 40 hours in each workweek as overtime at 1.5 times your entered hourly rate. You can change or disable that rule. Gross pay is an estimate before taxes, deductions, bonuses, or multiple-rate adjustments. A custom daily threshold is available in Advanced; it is not a full state-law payroll engine.

Frequently asked questions
Is this time clock calculator free?+
Yes. Calculate work hours, view results, download CSV files, and print a time card without signing up or providing an email address.
Can I enter military time or a 24-hour clock?+
Yes. Choose 24-hour format and enter times such as 09:00 and 17:30. In 12-hour format, choose AM or PM in the selector beside each time; you do not need to type it. Valid entered times are converted when you switch formats.
Does it automatically subtract lunch?+
No. Only enter and deduct the unpaid breaks you actually took. Mark a break as paid in the shift options to keep those minutes in your work hours.
Does it account for daylight saving time?+
The default uses clock-face time. To calculate actual elapsed time across a daylight saving change, open Advanced, enable time-zone calculation, choose the correct dates and time zone, and resolve any repeated or skipped local time.
Will my time card be saved automatically?+
No. Entries stay in the current page unless you choose Save locally. That action saves the report only in your browser, including any name, project, notes, and pay rate. You can restore it or delete that saved copy.
