Answer

100 Business Days Before Tomorrow Was
Monday, June 22, 2026

Days counted: June 22, 2026 – November 12, 2026 (November 13, 2026 itself is not counted)

144 calendar days = 100 business days + 40 weekend days + 4 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: 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.
