Apply the payroll 7-minute rule: enter any punch time and see how it rounds to the nearest quarter hour — with the full rounding chart, the FLSA neutrality requirement, and where rounding is now legally risky.

The 7-Minute Rule, Precisely

Quarter-hour rounding snaps punches to :00, :15, :30, :45 — and 15 minutes split as 7 down / 8 up:

The rule comes from the federal regulation permitting rounding (29 CFR 785.48) — allowed only when it averages out neutrally, paying employees fully over time. The same regulation permits 5-minute and 6-minute (tenth-of-hour) schemes; the quarter-hour version is just the most common.

Worked Examples

Example 1 — the classic pair. Clock in 8:07, clock out 4:38: in rounds to 8:00 (gain 7 min), out rounds to 4:45 (gain 7 min) — this day the employee gains 14 paid minutes. Tomorrow's 8:08/4:37 loses the same. That two-way symmetry is what makes it legal.

Example 2 — the grace-period myth. "You can be 7 minutes late free": true for pay (8:07 pays from 8:00), false for discipline — attendance policies can still count 8:01 as tardy. Two different systems.

Example 3 — systematic abuse. A system that rounds INs up (8:02 → 8:15) and OUTs down (4:58 → 4:45) shaves up to 28 minutes daily — the pattern behind major wage settlements. Your two-week check: compare raw punches with paid time on a few stubs; one-directional rounding is a claim, not a policy.

Where Rounding Law Is Heading

Rounding was born when mechanical clocks made exact math tedious — and courts increasingly ask why an electronic system that records to the second should round at all. California's courts have sharply restricted rounding (meal-period punches may not be rounded at all; neutrality must be proven with actual data, and exact records undercut the whole rationale), and class actions elsewhere follow the same logic. The direction of travel: pay from exact punches, use rounding only where genuinely justified. Employers keeping quarter-hour systems should run the neutrality audit annually — total rounded vs raw minutes, by employee — before someone else runs it for them.

Rounding × Overtime and Breaks

• Overtime threshold effects: rounded minutes count toward the 40-hour week — a systematically shaved 10 minutes daily can silently erase an hour of weekly overtime. Verify weeks near 40 hours with the time card calculator.
• Break punches: rounding a 30-minute meal to 15 or 45 distorts both pay and compliance — California forbids rounding these entirely; best practice everywhere is exact break punches (rules in the break time calculator).
• Decimal payroll: after rounding, minutes convert at ÷60 (a :15 quarter = 0.25) — the chart and rounding-mode options live in the timesheet to decimal converter.

For Employees: The Two-Week Self-Audit

1. Photograph or note your exact in/out times for 10 workdays.
2. Compare each against the paystub's paid hours — every rounding should be derivable from the 7/8 split.
3. Tally the net: neutral systems land within ±10 minutes over two weeks; consistent employer-favoring drift multiplied by your wage and 52 weeks is the size of your claim (2-3 year lookback under the FLSA).
4. Raise it in writing first — "my punches and paid time diverge one-directionally" resolves most cases at payroll level.

For Employers: Configuring Rounding Defensibly

If you keep rounding: symmetric 7/8 both directions on work punches, no rounding on meal punches, documented policy language, and an annual neutrality report retained with payroll records. If you drop it: pay to the exact minute and enforce schedule adherence through attendance policy instead — cleaner in audits and increasingly the norm in modern systems.
