If you want to count only Business Days
Answer
Days counted: May 22, 2026 – October 15, 2026 (May 21, 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: Memorial Day (Monday, May 25, 2026), Juneteenth (Friday, June 19, 2026), Independence Day (Friday, July 3, 2026, observed), Labor Day (Monday, September 7, 2026), Columbus Day (Monday, October 12, 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.
