What starts the clock, and tolling exceptions

Clock typically starts
Date of discovery (or date of act)
Most states use a discovery rule: the clock may start when you knew or should have known about the injury. A hard outer cap from the date of the act also applies in most states.
Government defendants
Notice of claim may be required
If your claim is against a government entity (a city, county, state agency, or public employee), most states require a separate notice of claim within 30 to 180 days. Missing this notice deadline can bar your claim entirely, independent of the SOL.
State-specific note: Wisconsin
Discovery rule; 5-year max from act.
Tolling: when the clock may pause
Medical malpractice deadlines are among the most complex: most states apply a discovery rule (clock starts when you knew or should have known), but with a hard outer cap from the date of the act. Minor patients and cases involving foreign objects left in the body often have separate rules.
