Quick answer: legal notice window business days
- Business day notice windows exclude weekends and holidays when set.
- Trigger date and service date can be different; inclusion mode controls edges.
- Holiday placement can shift the effective deadline by several days.
Why contracts specify business days
Contracts use business days to avoid weekend or holiday delays in service or delivery. Defining weekends and holidays up front prevents disputes about whether a notice was timely.
Common pitfalls
Pitfalls include mixing calendar days, ignoring service date versus trigger date, and not stating whether the end date counts. Inclusion mode and holiday selection address these issues.
