Algorithm for Computing Business Days Excluding Weekends & Federal Holidays
Calculating business days between two chronological endpoints requires more than simple calendar day subtraction. Commercial procurement, legal notice deadlines, and financial market settlement operations adhere to deterministic algorithms that isolate non-working weekends and statutory bank observances.
For any span of Δd calendar days:
W_biz = ⌊Δd / 7⌋ × 5
Every complete 7-day period contributes exactly 5 business days and 2 weekend days.
For residual days r = Δd % 7:
Iterate from Start + (Full Weeks × 7) to End. Add 1 for each day where day-of-week ∈ [Mon, Fri].
Subtract statutory public holidays that fall on a weekday:
Net = (W_biz + R_biz) − H_weekday
Spreadsheet Formulas & Programmatic Implementation References
In corporate financial modeling, supply chain planning, and payroll accounting, working days are standardly computed via built-in spreadsheet functions and programming libraries:
// Calculate net working days:
=NETWORKDAYS(A2, B2, HolidayList)
// Advance by 10 business days:
=WORKDAY(A2, 10, HolidayList)
// Custom weekend (e.g. Fri/Sat):
=NETWORKDAYS.INTL(A2, B2, 7, HolidayList)
// Deterministic standard library loop:
from datetime import date, timedelta
def count_biz_days(d1, d2, hols=set()):
cur, cnt = d1, 0
while cur <= d2:
if cur.weekday() < 5 and cur not in hols:
cnt += 1
cur += timedelta(days=1)
return cnt
Federal Reserve Bank Holiday Settlement & Next Business Day Convention
Under US Federal Law (5 U.S.C. 6103) and Federal Reserve Operating Circulars, commercial banking transactions, wire transfers (Fedwire), and Automated Clearing House (ACH) settlements do not process on designated public holidays. Under the statutory Next Business Day Convention (codified in legal practice under FRCP Rule 6(a)(1)(C)), when contractual deadlines or statutory filings land on an observed bank holiday, the legal performance deadline automatically extends to 11:59 PM on the subsequent business day.
