Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation as 'бизнес день'. Use 'рабочий день' but note this can also mean 'work shift'. For clarity, use 'банковский/рабочий день (кроме выходных и праздников)'.
- Confusion with 'calendar day' ('календарный день'). The key is the exclusion of weekends/holidays.
Common Mistakes
- Using 'business day' to include Saturdays (unless specified).
- Assuming all weekdays are business days (forgetting public holidays).
- Confusing '3 business days' with '3 days' (e.g., ordering Friday, expecting Monday).
