The answer on the day, month and year of birth is written down in figures in specially outlined frameworks.

[An example is omitted.]

[p.19]

It is not allowed to approximate or round the day, month and year of birth (e.g., for those who were born on the 9th or 11th you couldn't write the 10th; for those who were born in 1939 you couldn't write they were born in 1940, etc.). If the person enumerated indicated the year of birth ending with 0 or 5, you should make sure that he indicated the year correctly without rounding.

After the recording of the date of birth and without additional asking the respondent an enumerator determines and writes down the number of years that have passed in a specially outlined framework using the Supplemented table for indication the years for persons whose year of birth is known as of 5th of December 2001 (Appendix 1). For children less than 1 year 0 is written down.
