Answer

180 Business Days From December 31, 2025, Was
Friday, September 18, 2026

Days counted: January 1, 2026 – September 18, 2026 (December 31, 2025 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.
