01 / PURPOSE-SPECIFIC INPUTS

Clock-in-day shifts, located breaks and configurable overtime

Overnight shifts belong to their clock-in day/week. This is wall-clock arithmetic, not DST-aware elapsed time or a legal worldwide overtime model.

Rounding policy: No punch rounding · exact input minutes

Configurable arithmetic only, not a worldwide overtime or payroll-compliance policy. Time is recurring wall-clock time and not DST-aware. Do not deduct an unpaid gap twice by both excluding it between shift records and entering it as a break.

Overnight blocks can extend into the second 24-hour half of a row. Full shifts are assigned to their clock-in day; regular/OT bars are daily-policy totals, not a claim about legal minute-by-minute overtime allocation. No timezone or DST elapsed correction is inferred.

Formula, worked explanation & limitations

Record 5 nonoverlapping shifts relative to 2026-01-12. A clock-out earlier than clock-in is next-day; equal times are rejected. 12/24-hour display does not reinterpret explicit clock inputs.
Unpaid breaks are subtracted once; paid breaks are already inside gross shift time and are neither subtracted nor added again. One consecutive unpaid interval followed by a paid interval is located at the entered break start in each shift.
Regular/OT minutes use the selected daily/weekly/both thresholds. In combined mode, daily OT is separated first and weekly OT applies only to the remaining regular candidate minutes, avoiding double-counting.
No decimal-hour rounding is used to determine pay. Money rounds once, half up to cents. When thresholds create fractional minutes, pay uses thousandth-minute totals; display hours round independently.
Full overnight shifts, including a carry past the entered week, belong to their clock-in day/week in this model. Statutory workweek boundaries, timezone/DST elapsed-time corrections, legal wage rules, taxes and double-time tiers are not inferred.

Frequently asked questions

Can the time card include more than one shift per day?

Yes. Each record has a clock-in day offset, start/end and a located break block. Multiple records can share a day, but overlapping raw or rounded intervals, including overnight carry, are rejected.

How does this time card handle paid and unpaid breaks?

One unpaid interval followed by one paid interval is placed at the entered break start inside each shift. Only unpaid minutes are deducted. Paid breaks are already in gross time and are not added again.

How are daily and weekly time-card overtime combined?

Daily overtime is separated first. The weekly regular-hour threshold then applies only to the remaining regular candidates, so one minute is not paid as both daily and weekly overtime. These are user-selected arithmetic rules, not universal labor law.

What rounding policy does the time-card report use?

Default punches retain exact entered minutes. Optional nearest-five or nearest-fifteen-minute punch rounding uses ties upward, before duration arithmetic; break durations are not rounded. Decimal-hour display never determines pay, which rounds once to cents.

Which week receives an overnight time-card shift?

A clock-out earlier than clock-in is the next day, and the complete shift belongs to its clock-in day/week, including a carry past the entered week. Equal times are rejected rather than interpreted as a full day. Statutory workweek splitting and timezone/DST elapsed correction are not modeled.

What does the printable time-card report contain?

Daily gross, paid, regular and overtime minutes, plus the estimated weekly gross pay. The print action uses the browser’s local print facility; records are not submitted to an external payroll service or saved as an employee profile.
