How this is calculated
The reference is the site-local civil date in America/New_York. The start date is excluded and the end date is included. Dates use Eastern Time (America/New_York).
A calendar day is a date, including weekends and daylight-saving transitions. Negative signed counts indicate a date before the reference.
One offset week is exactly seven civil dates. ISO weeks start Monday and their week-year can differ from the calendar year.
