Answer
180 Business Days Before September 16, 2026, Was
Monday, December 29, 2025
Days counted: December 29, 2025 – September 15, 2026 (September 16, 2026 itself is not counted)
261 calendar days = 180 business days + 74 weekend days + 7 federal holidays
1,440 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.
The span holds 7 federal holidays. 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.
