Template:Years or months ago/doc

Template:Years or months ago displays the number of years (or months if less than 1 year) between a specified year/month date and the current year/month. It will also work correctly when only the year is given. Optionally, a second year/month date can be specified to be used instead of the current year/month.

This was designed as a supporting template for Template:Start date and age, to be used when the specified date does not include the day of the month. The formatting of the output was designed to be similar to Template:Time ago.

Usage
For years or months before or after current date:

For years or months between two dates:
