- Avoid translating as 'день из календаря'—it's a set term.
- In counting contexts, remember it includes weekends, unlike 'рабочий день'.
Common Mistakes
- Using 'calendar day' when you mean 'business day'.
- Writing 'calender day' (misspelling).
- Assuming 'calendar days' excludes weekends (it includes them).
