State rules · 50 states and DC
Overtime is not the same in every state.
The federal rule is overtime after 40 hours in a workweek. Some states also count by the day, add a seventh-day rule or set their own weekly rule. Every state’s row names its labor department, links the pages we read and gives the date we read them.

How we check numbers
Every rule has a source and a date.
Read the primary source
Federal rules come from the Department of Labor, the eCFR and the IRS; state rules from each state’s labor department, statutes or code. Not from summaries, vendors or forums.
Write the date beside it
Every rule line says when its sources were last read. When a rule changes, the date changes and the change goes in the public updates log.
Test the math
Each calculator runs against worked examples: overnight shifts, daylight-saving nights, daily and weekly overtime in the same week, every state’s rule.
What these calculators can’t see: a union contract, a company policy that pays more than the law, or a job that is exempt from overtime. When the answer matters, your pay records and your state labor department are the final word. A state we could not confirm from an official source is marked “not confirmed”, never guessed.
