Template:Birth and death year and age
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, or year and month, 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.
Such an approximation differs from the approximation generated by {{Birth based on age as of date}}; the latter can be used when the only detail available about someone's birth is a reference that establishes his or her age as of a certain date (such as the date that the reference was published).
The person's age is estimated as follows:
{{Birth year and age}}
Let us assume:
- that the person in question was born some time in 1970; and
- that the present date is 10 November 2025.
- If the person was born after 10 November 1970, then he will be 54 years old on 10 November 2025, as he has not had his 55th birthday yet. On the other hand, if he was born exactly on or before 10 November 1970, then he will be 55 years old.
- Therefore, the template
{{Birth year and age|1970}} - displays his birth year and age as: 1970 (age 54–55)
- Therefore, the template
- Optionally, if we know the person's birth month but not the day, we can also have the template display the month.
- Let us assume that the person was born in June 1970. Therefore:
- If it is presently January 2025, then this year the person has not had his birthday yet. Therefore, the template
{{Birth year and age|1970|6}}displays his birth year and age as: 1970 (age 54). - If it is presently June 2025, we do not know whether the person has had his birthday this year yet since his day of birth is unknown. Therefore, the template displays his birth year and age as: 1970 (age 54–55).
- If it is presently December 2025, then this year the person has already had his birthday. Therefore, the template displays his birth year and age as: 1970 (age 55).
- If it is presently January 2025, then this year the person has not had his birthday yet. Therefore, the template
- Let us assume that the person was born in June 1970. Therefore:
{{Death year and age}}
Let us assume:
- that the person in question was born some time in 1974; and
- that he died some time in 2024.
- We can posit as two extremes: (1) that the person was born on 31 December 1974 and died on 1 January 2024, in which case he would have been 49 years old at the time of his death, as they did not achieve his 50th birthday on 31 December 2024; and (2) that he was born on 1 January 1974 and died on 31 December 2024, in which case he would have been 50 years old at the time of his death as, he had his 50th birthday on 1 January 2024.
- Therefore, the template
{{Death year and age|2024|1974}} - renders his death year and age as: 2024 (aged 49–50)
- Therefore, the template
- Optionally, if we know the month of the person's death but not the day, we can also have the template display the month.
- Using the above examples and assuming the month is 11 (November)
- Therefore, the template
{{Death year and age|2024|1974|11}} - displays his death year and age as: November 2024 (aged 49–50)
- Therefore, the template
If you wish to set out the full dates of birth and/or death of a person and thus to calculate his age accurately, please use the templates {{Birth date and age}} and {{Death date and age}}.
