How many working days between January 1, 2026 and October 1, 2027?

Between January 1, 2026, and October 1, 2027, there are 438 business days.

Days counted: January 1, 2026 – September 30, 2027 (October 1, 2027 itself is not counted)

638 calendar days = 438 business days + 182 weekend days + 18 federal holidays

3,504 working hours at 8 hours a day

US federal business days: Monday to Friday, minus federal holidays on the day they are observed · state holidays not included.

The span holds 18 federal holidays. Banks count differently: the Federal Reserve does not move a Saturday holiday to Friday, so 2 of these Fridays are business days for banks, so a bank deadline can fall a business day earlier.
