සැකිල්ල: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:

1. that the person in question was born some time in 1969; and
2. that the present date is 19 දෙසැම්බර් 2024.

• If the person was born after 19 දෙසැම්බර් 1969 then she will be 54 years old on 19 දෙසැම්බර් 2024 as she has not had her 55th birthday yet. On the other hand, if she was born exactly on or before 19 දෙසැම්බර් 1969, then she will be 55 years old.

Therefore, the template {{Birth year and age|1969}}

displays her birth year and age as: 1969 (වයස 54–55)

• 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 1969. Therefore:

• If it is presently January 2024, then this year the person has not had her birthday yet. Therefore, the template {{Birth year and age|1969|6}} displays her birth year and age as: 1969 (age 54).
• If it is presently June 2024, we do not know whether the person has had her birthday this year yet since her day of birth is unknown. Therefore, the template displays her birth year and age as: 1969 (age 54–55).
• If it is presently December 2024, then this year the person has already had her birthday. Therefore, the template displays her birth year and age as: 1969 (age 55).

{{Death year and age}}

Let us assume:

1. that the person in question was born some time in 1973; and
2. that he died some time in 2023.

• We can posit as two extremes: (1) that the person was born on 31 December 1973 and died on 1 January 2023, in which case he would have been 49 years old at the time of his death as he did not achieve his 50th birthday on 31 December 2023; and (2) that he was born on 1 January 1973 and died on 31 December 2023, 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 2023.

Therefore, the template {{Death year and age|2023|1973}}

renders his death year and age as: 2023 (වයස 49–50)

• Optionally, if we know 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 12 (දෙසැම්බර්)

Therefore, the template {{Death year and age|2023|1973|12}}

displays his death year and age as: දෙසැම්බර් 2023 (වයස 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.
