2. Write the Month Name
Next, write the month using its full name.
For example:

So:
15-05 → Fifteenth May
The 12 months of the year are:
| Number | Month |

| 01 | January |

So:
15-05-1990 → Fifteenth May, Nineteen Ninety
The exact way a year is spoken or written can vary depending on context. For formal documents, follow the format requested by the organisation or form.
4. Combine the Complete Date
After converting the day, month, and year, combine them to form the complete date.
For example:
15-05-1990
can be written as:
Fifteenth May, Nineteen Ninety
Another commonly used style is:

Both styles communicate the same date. If you are filling out an official form, use the format specified on the form.

Common Mistakes When Writing Date of Birth in Words
Here are some common mistakes to avoid:
Using a Cardinal Number Instead of an Ordinal Number: For example, when writing the day 15, use Fifteenth rather than simply Fifteen when the date is being written in ordinal form.
Spelling the Month Incorrectly: Always use the correct spelling of the month, such as February, September, and November.
Confusing the Date Format: Be careful when reading numeric dates. Depending on the country or document, a date such as 05/08/1995 can be interpreted differently. If there is any doubt, use the full month name.
Using the Wrong Year: Double-check the year before submitting a form or document. A small error in the year can change the person’s date of birth completely.
Ignoring Form Instructions: If an official form specifies how the date should be entered, follow those instructions.
