" class="reference-link">R-bizdays

bizdays computes business days between dates based on collections of
nonworking days and nonworking weekdays (usually weekends). It also
helps with other issues related to business days calculations like check
whether a date is a business day, offset a date by a number of business
days, adjust dates for the next or previous business day, create
generators of business days sequences, and much more. All functions are
vectorizable so that speed up the calculations for large collections of
dates.
