Module:Age range

Module documentation[view] [edit] [history] [purge]

Purpose

This module provides a simple way to display an automatically updating age range when only an approximate birth year is known (e.g. "1991/1992"). It is designed to be used when the exact year of birth is uncertain but falls within a known range of two consecutive years.

Usage

Invoke the module using:

{{#invoke:Age range|ageRange|<earlier year>|<later year>}}

Example:

Born 1991/1992 (age {{#invoke:Age range|ageRange|1991|1992}})

As of 2026, this would output:

Born 1991/1992 (age 33–34)

Parameters

• 1 – The earlier possible year of birth (e.g. 1991)
• 2 – The later possible year of birth (e.g. 1992)

Returns

A string in the format:

• 33 if both years produce the same age
• 33–34 if the years produce a range of ages

Examples

Wikitext	Output (as of 2026)
36	36
34–35	34–35
40–41	40–41

• Module:Age – for precise age calculation
• Template:Birth date – for exact known birthdates

Notes

• This module assumes birth has already occurred this year.
• Does not account for specific months or days.
• Use only when the birth year is narrowed to two possibilities.
