Calculating How Old Someone Will Be in a certain year

[Chris waller]

I have a list of dates (birthdays & Anniversaries) in the dd/mm/yyyy format
down a column, with the years in the format yyyy across the first row. I want
a formula that will calculate the age of the person or anniversary by using
just the year part of the date and comparing it with the year across the
first row of the spreadsheet. TIA

Do you have a year or a date? A year "in the format yyyy" is actually a
date.

If you have a year, the formula is:
=b$1-year($a2)

If you have a date, it's:
=year(b$1)-year($a2)
