Work hours guides
These guides answer the questions that come up after a calculator shows a number: how to add two workweeks without averaging overtime, why a night shift is marked next day, whether lunch should be subtracted, and why 7:30 is 7.50 in decimal hours. Each guide includes a worked example and the limit of the simple model.
Two-week work hours and pay
Calculate a 38-hour and 45-hour week at $20 per hour. See the overtime and gross-pay difference that averaging would hide.
Overnight shifts and workweek boundaries
Count a shift that crosses midnight, then check what happens when it also crosses the start of a fixed workweek.
Unpaid breaks and weekly overtime
See how a meal break changes worked time and why two workweeks should not be averaged for the basic federal overtime test.
Hours and minutes to decimal hours
Use a conversion table, learn when two-decimal display rounding happens, and avoid reading 7:30 as 7.30 hours.
Review a time card against a pay statement
Follow a concrete sequence for checking dates, punches, breaks, totals and estimated pay without sharing personal records.
Add two shifts in one day
Use an off-duty gap to check a split shift, and learn when a single row cannot represent the underlying punches.
Exact minutes versus rounded punches
Compare an 08:07–16:53 shift using exact entries and illustrative rounded punches.
Review monthly work hours
Sum exact minutes for a calendar month while keeping weekly overtime tied to full workweeks.
