Final answer:
The last day is typically included in the statute of limitations but exceptions exist, such as concealed information causing unawareness of the violation. Lilly Ledbetter's case led to the Lilly Ledbetter Fair Pay Act, allowing each discriminatory paycheck to reset the limitations period.
Step-by-step explanation:
The last day is included in the statute of limitations unless a specific exception applies, such as when the injured party is unaware of the violation due to the information being concealed from them. A case in point is the situation faced by Lilly Ledbetter, whose salary discrimination was not discovered until well after the typical statute of limitations period had expired. Her situation led to the passage of the Lilly Ledbetter Fair Pay Act, which reset the limitations period with each discriminatory paycheck rather than the original decision to discriminate, acknowledging the ongoing nature of some discriminatory acts.
