About ShiftClock

ShiftClock is a free reference site for shift workers and the payroll teams that support them. We focus on one specific problem: figuring out what a paycheck should look like when the schedule is anything other than a straight Monday-through-Friday, nine-to-five workweek.

The site is organized around four directories: calculators for time-on-the-clock math, schedule patterns that explain how 24/7 rotations are built, an occupations directory with median wages and rule references, and an industries directory that rolls those occupations up into staffing-model views. Each entry connects back to the others so you can move from a paycheck question to the right calculator in two or three clicks.

We are not a payroll provider, a staffing agency, or a law firm. ShiftClock is informational. Our calculators are designed to be a fast second source — not a replacement for a payroll system or for advice from a qualified attorney when something is in dispute.

Wage anchors come from U.S. Bureau of Labor Statistics OEWS bulletins. Schedule, break, and overtime rules are aligned with the U.S. Department of Labor Wage and Hour Division materials at dol.gov/agencies/whd/flsa. The methodology page describes how we sourced and combined the data.

If you find a number that looks off or a rule that needs an update, please tell us. The directory grows as the user community sends in corrections.
