__NOTOC__  Usage The templates  and  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  ; 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 examples on this page use the current date as      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 ; and that the present date is   .  If the person was born after    then she will be  years old on    as she has not had her 55th birthday yet. On the other hand, if she was born exactly on or before   , then she will be 55 years old.   Therefore, the template  displays her birth year and age as:   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 . Therefore: If it is presently January , then this year the person has not had her birthday yet. Therefore, the template  displays her birth year and age as:  (age 54). If it is presently June , 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:  (age 54–55). If it is presently December , then this year the person has already had her birthday. Therefore, the template displays her birth year and age as:  (age 55).  {{Death year and age}} Let us assume: that the person in question was born some time in ; and 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 he would have been 49 years old at the time of his death as he did not achieve his 50th birthday on 31 December ; and (2) that he was born on 1 January  and died on 31 December , 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 .   Therefore, the template  renders his death year and age as:   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  () Therefore, the template  displays his death year and age as:   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  and .  Note: Do not use this template inside the Wikipedia:Persondata template as it can interfere with data extraction.
