No regional holiday feed is assumed. Custom exclusions remain visible in the audit so the answer can be reproduced for a school, company, country or contract-specific calendar.

Date-only calculations use UTC-normalized Gregorian dates so DST clock changes do not create 23- or 25-hour day errors. The elapsed count excludes the start date by default.
