How the service method changes the date

The period runs from service, and the method of service can extend it. Under CPLR 2103(b), mail adds 5 calendar days, overnight courier adds 1 business day, and NYSCEF e-service adds 2 days under Uniform Rule 202.5-b(f)(2). Personal delivery adds nothing. When the last day falls on a Saturday, Sunday, or New York public holiday, the deadline rolls to the next business day (CPLR 2103(a); General Construction Law §25-a).
