On the other hand, if she was born exactly on or before [[1 July]] [[1950]], then the person will be 55 years old.

Usage

The templates {{Birth year and age}} and {{Death year and age}} return a person's year of birth or death and his or her approximate age. The templates are useful when only the year of a person's birth and/or death are known, or if it is desired not to state a person's full dates of birth and death for privacy reasons.

The examples on this page use the current date as
January 22, 2026

The person's age is estimated as follows:

  1. that the person in question was born some time in 1971; and
  2. that the present date is 22 January 2026.
If the person was born before 22 January, 1971 then they will be 54 years old on 22 January 2026 as they have not had their 55th birthday yet. On the other hand, if they were born exactly on or before 22 January, 1971, then the person will be 55 years old.
Therefore, the template {{Birth year and age|1971}}
displays their birth year and age as: 1971 (age 54–55)
  • Optionally if we know the persons birth month but not day, we can have the template also display the month.
Using the above examples and assuming the month is 01 (January)
Therefore, the template {{Birth year and age|1971|01}}
displays their birth year and age as: January 1971 (age 54–55)
  1. that the person in question was born some time in 1975; and
  2. that he died some time in 2025.
We can posit as two extremes: (1) that the person was born on 31 December 1975 and died on 1 January 2025, in which case they would have been 49 years old at the time of their death as they did not achieve their 50th birthday on 31 December 2025; and (2) that they were born on 1 January 1975 and died on 31 December 2025, in which case they would have been 50 years old at the time of their death as they had his 50th birthday on 1 January 2025.
Therefore, the template {{Death year and age|2025|1975}}
renders his death year and age as: 2025 (aged 49–50)
  • Optionally if we know the persons month they died but not the day, we can have the template also display the month.
Using the above examples and assuming the month is 01 (January)
Therefore, the template {{Death year and age|2025|1975|01}}
displays their birth year and age as: January 2025 (aged 49–50)

If you wish to set out the full dates of birth and/or death of a person and thus to calculate his or her age accurately, please use the templates {{Birth date and age}} and {{Death date and age}}.

Note: Do not use this template inside the Wikipedia:Persondata template as it can interfere with data extraction.

Syntax

{{Birth year and age|year of birth}}
{{Birth year and age|year of birth|optional month of birth}}
{{Death year and age|year of death|year of birth}}
{{Death year and age|year of death|year of birth|optional month of death}}

Examples

Template text Result
{{Birth year and age|1971}} 1971 (age 54–55)
{{Birth year and age|1971|01}} January 1971 (age 54–55)
{{Death year and age|2025|1975}} 2025 (aged 49–50)
{{Death year and age|2025|1975|01}} January 2025 (aged 49–50)
