You can paste these formulas into fields in AllDrafts to create smart documents with dynamically calculated dates. You can also use them in Excel or Google Sheets; replace Start_Date with a cell reference or name a cell containing a date Start_Date. USHOLIDAYS() is available in AllDrafts, but not in Excel or Google Sheets. You can remove , USHOLIDAYS() from formulas, or replace it with a reference to an array of holiday dates.
Calculated using US Federal Holidays from 01/01/2020 through 12/25/2058.
