Counting Working Days
Working days exclude weekends and bank holidays. Standard: Monday-Friday counts (5 days/week). UK: 252 working days in a typical year (365 - 104 weekends - 8 to 9 bank holidays). US: 250 (365 - 104 - 11 federal holidays). Varies by country and year (leap years +1, weekend bank holidays may shift).
Used in: project management (deliverable timelines), legal deadlines (X working days from notice), payment terms (net 30 working days), employment law (notice periods), HR (annual leave calculations). Different from calendar days - 30 calendar days from Monday is a Wednesday in 4 weeks; 30 working days is 6 weeks.

Frequently Asked Questions
Are working days the same as business days?
Yes - terms are interchangeable. Both mean weekdays excluding public holidays. Some legal/business contexts further distinguish 'court days' (excluding court holidays specifically), but for general purposes 'working days' = 'business days' = Monday-Friday, excluding bank holidays.
Does 5 working days from Monday = Friday?
Depends on counting convention. 'Within 5 working days' usually means starting next day, so 5 working days from Monday = Friday following week. 'On the 5th working day' = Friday same week. Always check what the convention is in the specific context (legal, contractual).
