Answer

100 Business Days From June 18, 2026, Will Be
Thursday, November 12, 2026

Days counted: June 19, 2026 – November 12, 2026 (June 18, 2026 itself is not counted)

147 calendar days = 100 business days + 42 weekend days + 5 federal holidays

800 working hours at 8 hours a day

Counted in US federal business days: weekends and the federal holidays of 5 U.S.C. §6103 are skipped, each on the day it is observed.

Federal holidays in the span: Juneteenth (Friday, June 19, 2026), Independence Day (Friday, July 3, 2026, observed), Labor Day (Monday, September 7, 2026), Columbus Day (Monday, October 12, 2026), Veterans Day (Armistice Day) (Wednesday, November 11, 2026). Banks count differently: Friday, July 3, 2026 is a business day for banks that follow the Federal Reserve, which does not move a Saturday holiday to Friday, so a bank deadline can fall a business day earlier.
