Template documentationThis template may be used to display a person's or entity's lifespan in years, and optionally their age, also in years. Additional options handle ambiguous dates, or affect presentation; error messaging is available for some usage errors.

Syntax and presentation
For basic use, only the birth and death dates (in years) are required. Years must be entered with all digits (1 to 4 depending on century).
Depending on the parameters used, default presentation and formatting elements including static text, white space and additional punctuation may be displayed.
All parameter names must be in lowercase; optional parameters are ignored when they are misspelled or unrecognized. Dependent and conditional parameters are ignored if their prerequisite parameter(s) or conditions are absent.
Copy a blank version from the box above to use. Insert the "|" (pipe) character between each parameter. Delete unused parameters.
The template's output is enclosed in parentheses by default; they may be removed, or may be used to enclose the optional age component only.
See § Parameters for important details.
Parameters

- Parameters birth (or its alias b) and death (or its alias d) are required.
- Parameters label (content label, alias l) and prefix (birth/death prefixes, alias pfx) cannot be used concurrently.
- Parameters ca (circa) and or (birth and/or death is either of 2 years) cannot be used concurrently.
- Parameters birth2 (alias b2) and death2 (alias d2) depend on parameter or.
- Parameters birth2 and death2 respectively must have greater absolute value than the corresponding parameters birth and death.
- Parameter yrs (age in years) depends on parameter age-range (range of ages in years).
- Parameters or and yrs cannot be used concurrently.
