## Overview

The first half of 2026 — January through June — contains 124 working days under the US Mon–Fri, federal-holidays schedule. Five federal holidays fall in this window: New Year's Day (Jan 1), Martin Luther King Jr. Day (Jan 19), Presidents' Day (Feb 16), Memorial Day (May 25), and Juneteenth (Jun 19). Project managers often split annual capacity into H1 and H2; this figure is your H1 baseline.

## 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.
