Answer

90 Business Days Before September 21, 2026, Was
Tuesday, May 12, 2026

Days counted: May 12, 2026 – September 20, 2026 (September 21, 2026 itself is not counted)

132 calendar days = 90 business days + 38 weekend days + 4 federal holidays

720 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: Memorial Day (Monday, May 25, 2026), Juneteenth (Friday, June 19, 2026), Independence Day (Friday, July 3, 2026, observed), Labor Day (Monday, September 7, 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.
