Ordinal numbering: 21st century = 2001–2100 (strict), 2000–2099 (popular).
Rarely useful in engineering — years or decades are more practical.

Avoid these

Writing 20th century when meaning 1900s — they overlap but differ in first/last year.
Treating century exactly as 100 × 365 days — ignores leap years.
Mixing calendar systems (Gregorian vs. Julian) across centuries — matters pre-1582.
