What does Business Days HQ do?
Business Days HQ is a free business-days calculator that counts between dates or adds and subtracts working days. Users choose weekdays and endpoint inclusion, optionally use the standard Monday–Friday US federal observed holiday preset, and add custom closure dates. A date-by-date breakdown, CSV download and print option make the count auditable. Six original guides cover endpoints, observed holidays, custom calendars, leap years and project scheduling. The tool explains its calendar limits and does not represent every employer or legal deadline calendar. No account is required.
