Answer

366 Business Days Ago Was
Thursday, May 1, 2025

Days counted: May 1, 2025 – October 17, 2026 (today is not counted)

535 calendar days = 366 business days + 153 weekend days + 16 federal holidays

2,928 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 16 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.
