How this page earns its URL
Search intent: Best answer for adding a week of clock-in and clock-out times.
Nearest sibling: Different from Hours Between Times because this page totals several days and applies breaks plus overtime.
Worked check: Five 8-hour days with 30-minute unpaid breaks = 37.5h; a 45h week at a 40h threshold has 5h overtime.
A time card is several clock-span calculations added together. Each row converts in and out times to elapsed minutes, subtracts the unpaid break and turns the result into decimal hours. The weekly total then splits regular and overtime hours at the threshold.
The default threshold is 40 hours because that is a common weekly overtime breakpoint, but employment rules vary. The page does not make legal claims about overtime eligibility; it shows the arithmetic so a user can compare it with their award, contract or payroll policy.
Good date and time tools need to be explicit about what is being counted. Two people can ask the same words and mean different things: elapsed days, calendar cells touched, working days, overnight clock span, ISO week, local civil time or payroll hours. This page names that intent before it shows the number. That is why sibling calculators stay separate when the question is meaningfully different and why redirect recommendations are called out when two slugs collapse to the same job. The other trust boundary is local time. A browser can format IANA time zones with Intl, but holidays, employment rules, rosters, school calendars and payroll policies are human systems. The calculator gives a transparent arithmetic core, visible assumptions, code snippets and a printable worksheet so a user can compare the result with the official calendar, award, contract or schedule that governs their real situation.
The practical way to audit this calculation is to write down the inputs in the same units the page uses, do the smallest possible independent count, and then compare that count with the displayed result. For date pages that means checking the first day, last day, inclusion rule and whether the count is elapsed or inclusive. For clock pages it means converting each clock time to minutes from midnight, doing the subtraction, and only then converting back to hours and minutes. For week-number and world-clock pages it means checking the governing convention: ISO Monday weeks for ISO labels, IANA zone names for civil time, and a single instant shared across every displayed city. The worksheet is deliberately written like an audit slip because date and time errors are often off-by-one errors that only become obvious when the convention is visible.
The visual is part of that audit, not decoration. A span that crosses midnight should look different from a same-day span. A counted date range should show the start and landing points rather than merely printing a number. A week-number page should remind the user that weeks are a grid over a year, not a property of a single month. A time-card page should show daily bars because one long day and five moderate days can produce the same weekly total while meaning different things operationally. The Playwright check changes an input and asserts the SVG geometry changes so the drawing cannot silently drift into a static illustration.
The code panel is intentionally small. It does not try to replace a full calendar library or a payroll system. It prints the headline result for the current inputs using standard Python or JavaScript so a reviewer can reproduce the number outside the page. That is useful for classrooms, blog posts, job notes, invoices and internal QA because the copied report, printable sheet and code snippet all describe the same current calculation. When this page says a sibling should be reviewed for redirect, that is also a product-quality claim: CalculationTime should keep pages when they answer meaningfully different jobs, and collapse pages when the only difference is wording around the same engine.
FAQ
Questions people ask about time card calculator
How are unpaid breaks handled?
Each row subtracts its unpaid break minutes after the clock-in to clock-out span is calculated.
Can a row cross midnight?
Yes. If the clock-out time is earlier than clock-in, the row is treated as an overnight span.
What does the overtime threshold do?
The weekly total is split into regular hours up to the threshold and overtime hours above it.
Does this decide legal overtime eligibility?
No. It performs arithmetic only; employment law, awards and contracts can add rules.
Why show HH:MM and decimal hours?
Timesheets often need decimal hours for payroll and HH:MM for human checking.
How is this different from Hours Between Times?
Hours Between Times solves one span. This page totals a week of rows with breaks and overtime.
