## Overview

2027 also delivers 250 US working days — the same total as 2026. The holiday count stays constant, but individual holiday dates shift: for example, New Year's Day (January 1) falls on a Friday in 2027, so it lands on a weekday rather than being observed on Monday. Use the calendar view to spot months with high or low working-day counts for resource planning.

## Method

The engine iterates every calendar day in the inclusive range [start, end] in UTC to avoid daylight-saving drift. Each day is classified as weekend (if its day-of-week is in the chosen weekend pattern), holiday (if it appears in the built-in or custom holiday set), or working. Weekend takes precedence over holiday. US federal holiday dates follow the rules published by the US Office of Personnel Management: fixed-date holidays shift to Friday when they fall on Saturday and to Monday when they fall on Sunday. UK bank holidays for England and Wales follow the GOV.UK bank-holiday data, with substitute days rolling forward to the next free weekday. Easter is computed using the Anonymous Gregorian algorithm. The "add business days" direction walks forward or backward one day at a time, skipping non-working days until the requested count is exhausted.
