Birthday: Just the year?

When editing a person on the wiki, is there a way to add just the person's birth year if the exact date is not known?

I've fallen into a wiki-editing vortex and can't update the Haruhiko Shono page. He was born in 1960.

This is also a problem with Company pages. You can only add the EXACT date on a company page, down to the day. 90% of the time this information isn't known. Only a companies webiste they might say "we were founded in July of 2002". But you can't add fuzzy dates, so you cant add it.

We could really use fuzzy dates for companies, I have run into many occasions of a company only listing the year they were founded.
