Answer

666 Business Days Ago Was
Wednesday, February 28, 2024

Days counted: February 28, 2024 – October 24, 2026 (today is not counted)

970 calendar days = 666 business days + 277 weekend days + 27 federal holidays

5,328 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 27 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.
