Weekly time clock
Enter each day’s punches. Leave a day blank for a day off. Overnight shifts (clock-out earlier than clock-in) roll past midnight automatically. Overtime pays 1.5× past 40 hours.

Time Clock Calculator
Punch in a full week of shifts — clock-in, clock-out, and unpaid break for each day — and get total hours, 1.5× overtime past 40 hours, and gross pay. Monday–Friday 9–5 with a 30-minute break at $20/hr is 37.50 hours and $750.00 — add Saturday 9–1 and it becomes 41.50 hours and $845.00. Unlike the work hours calculator (one shift plus a weekly view), this one takes seven separate punch entries and explains quarter-hour rounding too.

Quarter-hour rounding explainer
Many time clocks round punches to the nearest 15 minutes using the 7-minute rule: 1–7 minutes past the quarter rounds down, 8–14 rounds up. So 9:07 becomes 9:00 and 9:08 becomes 9:15.
The 60-second rule
Paid hours = ∑ (clock-out − clock-in − unpaid break), day by day. Overtime kicks in past 40 hours at 1.5× the rate: gross = 40 × rate + overtime × 1.5 × rate. At the defaults — Monday–Friday 09:00–17:00 with a 30-minute unpaid break — each day pays 7.50 hours, the week totals 37.50 hours, and at $20/hr the gross is $750.00, with no overtime.
The worked examples, line by line
Setup: Mon–Fri 09:00–17:00, 30-minute unpaid break each day, $20/hr.
One day. 17:00 − 09:00 = 8.00 hours, minus 0.50 break = 7.50 paid hours.
The week. 7.50 × 5 = 37.50 hours (37:30). Under the 40-hour threshold, so overtime = 0. Gross: 37.50 × $20 = $750.00.
Branch — add Saturday 09:00–13:00, no break: Saturday adds 4.00 hours → 41.50 hours. Regular: 40 × $20 = $800.00. Overtime: 1.50 × $30 = $45.00. Gross: $845.00. One half-day Saturday is worth $95.00 at these rates.
Branch — the overnight shift: Friday 22:00–05:00 with no break. Clock-out (05:00) is earlier than clock-in (22:00), so the panel rolls it past midnight: 7.00 paid hours. Overnight shifts count exactly like day shifts — the only special case is the date line.
Rounding branch — 9:07 vs 9:08: 9:07 is 7 minutes past the quarter → rounds down to 9:00. 9:08 is 8 minutes past → rounds up to 9:15. The 7-minute rule is symmetric: it neither favors the worker nor the employer by design.
Output · formula · meaning
| Output | Formula | What it means |
|---|---|---|
| Total hours | ∑ (out − in − break) per day | 37.50 h (37:30) at the defaults — every paid hour of the week. |
| Regular hours | min(total, 40) | 37.50 h at the defaults — hours paid at the straight rate. |
| Overtime hours | max(0, total − 40) | 0.00 h at the defaults; 1.50 h in the Saturday branch — paid at 1.5×. |
| Weekly gross pay | regular × rate + overtime × 1.5 × rate | $750.00 at the defaults; $845.00 in the Saturday branch. |
| Rounded time | nearest 15 min (7 down, 8+ up) | 9:07 → 9:00, 9:08 → 9:15 — how quarter-hour clocks treat punches. |
Who uses this
- The hourly worker: punches in the week’s shifts to check the paycheck — 37.50 h × $20 = $750.00 — before it lands.
- The shift supervisor: totals a crew member’s mixed week (days, a Saturday, an overnight) to approve hours without a spreadsheet.
- The freelancer: logs client-site days with different start times, subtracts lunch, and invoices the exact 41.50 hours.
- The payroll skeptic: types 9:07 into the rounding panel, sees 9:00, and understands why the stub says what it says.
Accuracy & limitations
This is a math helper, not payroll software. Overtime here is the federal weekly rule (1.5× past 40 hours); some states add daily overtime (California, Alaska) or double time, which this panel does not model. Rounding policies vary by employer — some round to the nearest 6 minutes, some to the nearest quarter, some not at all; the panel explains the most common rule. Unpaid breaks are subtracted exactly as entered; paid breaks should be entered as 0. This ignores taxes, tips, shift differentials, holiday pay, and PTO — it computes gross from hours and rate only.

What’s the difference between this and the work hours calculator?
The work hours calculator takes one shift (plus a weekly view); this page takes seven separate punch entries — different start times each day, overnights, a Saturday half-day — and adds the quarter-hour rounding explainer. Use this one when every day looks different.
How does overtime work here?
Hours past 40 in the week pay 1.5× the hourly rate. 41.50 hours at $20/hr is 40 × $20 + 1.50 × $30 = $845.00. Daily overtime (California, Alaska) is not modeled.
What if my shift crosses midnight?
Enter it normally — a 22:00 clock-in with a 05:00 clock-out is recognized as an overnight shift and counted as 7.00 hours. The verdict flags how many overnights it found.
What is the 7-minute rounding rule?
Quarter-hour time clocks round each punch to the nearest 15 minutes: 1–7 minutes past the quarter rounds down, 8–14 minutes rounds up. So 9:07 → 9:00 and 9:08 → 9:15. It is symmetric by design.
Is quarter-hour rounding legal?
In the US, the Department of Labor permits rounding if it is neutral on average — it cannot consistently shave the worker’s time. The 7-minute rule qualifies because it rounds up as often as down. Employer policies still vary, so confirm yours.
Do unpaid breaks get subtracted?
Yes — the break minutes you enter each day are subtracted from that day’s shift. A 30-minute lunch on an 8-hour shift leaves 7.50 paid hours. Paid breaks should be entered as 0.
Why do my hours differ from my paycheck?
The usual suspects: your employer rounds punches (see the rounding panel), applies different overtime rules, or deducts a meal break you didn’t enter. This calculator shows the unrounded math — the rounding panel shows the other half of the story.
