Date of Birth in Words - Complete Step-by-Step Guide
1. What is DOB in Words?
DOB in Words means writing your Date of Birth using words instead of numbers. It is required in official documents, certificates, resumes, legal affidavits, and more. Converting your DOB into words avoids ambiguity and maintains formal correctness.
2. How to Write DOB in Words (Step-by-Step)
- Start with the day of birth: convert numeric day to ordinal word (1 → First, 31 → Thirty First).
- Write the month in words (January, February, etc.).
- Convert the year to full words (2000 → Two Thousand, 1995 → Nineteen Ninety Five).
- Select the format depending on document:
- Birth Certificate: ALL-CAPS ordinals, month uppercase, year in ALL CAPS, hyphen '-' between day, month, year.
- Education: Title Case ordinals, month in Title Case, year in Title Case words.
- Legal: "The [Ordinal] Day Of [Month], [Year in words]" style.
- General Use: Numeric day with suffix, Month, Numeric Year.
- Validate the date before writing (check day, month, year and leap years).
- Write carefully to avoid mixing formats.
