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 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 ; and
 * 2) that the present date is 29 July 2024.


 * If the person was born before 29 July, then they will be 23 years old on 29 July 2024 as they have not had their 55th birthday yet. On the other hand, if they were born exactly on or before 29 July,, then the person will be 55 years old.


 * Therefore, the template
 * displays their birth year and age as:


 * 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 July (July)
 * Therefore, the template
 * displays their birth year and age as: July undefined


 * Death year and age – let us assume:
 * 1) that the person in question was born some time in ; and
 * 2) that he died some time in.


 * We can posit as two extremes: (1) that the person was born on 31 December and died on 1 January, 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 ; and (2) that they were born on 1 January  and died on 31 December , 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.


 * Therefore, the template
 * renders his death year and age as:


 * 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 July (July)
 * Therefore, the template
 * displays their birth year and age as: July undefined

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 Persondata template as it can interfere with data extraction.
