Answer

638 Business Days Ago Was
Thursday, April 11, 2024

Days counted: April 11, 2024 – October 28, 2026 (today is not counted)

931 calendar days = 638 business days + 266 weekend days + 27 federal holidays

5,104 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.
